Chairman’s Letter

Dear Shareholder,

Vanguard Windsor Fund returned about 16% for the fiscal year ended October 31, 2010, modestly outperforming its benchmark index, the Russell 1000 Value Index, and the average return for multi-capitalization value funds.

The Windsor Fund’s result reflects the U.S. stock market’s bumpy ride during the period. The fund posted strong double-digit gains in the first six months as the stock market continued its path to recovery, but then dipped into negative territory in the second half as a skittish global stock market slid in late spring and continued into the summer. A powerful rally late in the fiscal year and earlier gains lifted the fund’s results for the 12 months.

For the fiscal year, the Windsor Fund’s consumer discretionary, industrial, and health care holdings contributed most to its result. Financials, the fund’s largest holding by sector, posted the weakest return.

If you own shares of the Windsor Fund in a taxable account, you may wish to review the fund’s after-tax returns presented later in this report.

Also, please note that on October 6 Vanguard broadened the availability of our lower-cost Admiral Shares. We reduced the Admiral minimums on most of our actively managed funds to $50,000 from $100,000, as part of our ongoing efforts to lower the cost of investing for our clients.

Stock market performance was better than it felt
Global stock prices rallied at the start of the period, but struggled through the spring and summer, weighed down by Europe’s sovereign debt crisis and the slow pace of economic recovery in the United States. In the fiscal year’s final months, the mood turned. Stock prices climbed on continued strength in corporate earnings. In the United States, stocks also seemed to get a boost from the Federal Reserve Board’s hints that it would try to stimulate the economy with a second round of U.S. Treasury bond purchases. (In early November, the Fed announced that it would buy as much as $600 billion in Treasuries.)

For the 12 months, the broad U.S. stock market returned about 19%, a performance that was better than it felt in a year of ups and downs. Small-capitalization stocks did even better. International stocks returned about 13% on the strength of a powerful rally in emerging markets and solid single-digit gains in developed markets in Europe and the Pacific region.

Despite shrinking yields, bonds attracted investor dollars
Although fixed income yields have fallen to generational lows, investors continued to bid up bond prices. The broad U.S. bond market produced a 12-month return of about 8% as the yield of the 10-year U.S. Treasury note fell from 3.39% at the start of the period to 2.61% at the close.

Tax-exempt municipal bonds also rallied. Bond prices and yields move in opposite directions, of course, so abundant returns built on rising prices could mean leaner pickings in the years ahead.

The yields of money market securities hovered near 0%, consistent with the Federal Reserve Board’s target for short-term rates.

Consumer discretionary and industrials boost performance
The Windsor Fund’s two advisors—Wellington Management Company and Alliance Bernstein—focus on out-of-favor stocks with strong fundamentals and potential for long-term growth. This investment strategy gives the fund leeway to hold proportions of sectors and stocks that differ from those of its benchmark index.

For the fiscal year ended October 31, the fund reported positive returns in all ten stock sectors; eight sectors posted double-digit gains. The consumer discretionary, industrial, and health care sectors, made the most significant contributions to performance.

As the global economy slowly gathered momentum, the fund’s industrial stocks recorded the best results for the period with a return of roughly 40%. A combination of financial discipline and some recovery in travel helped Delta Air Lines, a standout performer with a return of about 94% for the fiscal year. Farm and construction

equipment manufacturer Deere (+72%) also benefited from increased demand from the United States and abroad.

A modest rebound in consumer confidence lifted a broad cross-section of companies in the consumer discretionary sector, including top-ten holdings Virgin Media and Comcast. Both cable companies earned double-digit gains for the fiscal period thanks in part to growth in their high-speed internet subscriptions.

In health care, managed care companies performed well for the fiscal year. Holdings including CIGNA and UnitedHealth benefited from membership gains and strong revenue growth.

Financials, the fund’s largest sector weighting, was the biggest restraint on the fund’s performance. Some of the fund’s investment and commercial banks produced dismal returns as the companies continued to grapple with the regulatory and financial aftershocks of the markets’ recent downturn. Among the poor performers included TD Ameritrade (–11%) and Wells Fargo (–5%).

Relative to its benchmark, the fund benefited from the advisors’ choices in industrials and energy. In industrials, both the fund and the benchmark held a similar weighting for the period, yet the fund outperformed the benchmark by more than 10 percentage points because of

superior stock selection. Compared with its index, the fund also benefited from its caution about several big energy companies, including Exxon Mobil, which declined for the year.

Advisors’ strategy and talent keep long-term record strong
For the decade ended October 31, 2010, the Windsor Fund posted an average annual return of 3.28% for Investor Shares, ahead of the annualized returns of its benchmark index (+2.64%) and its peer group (+2.44%) for the period.

Despite two severe market downturns—the collapse of the tech bubble earlier in the decade and the recent financial crisis—the fund has managed to outpace its comparative standards. The fund’s market-beating performance over the past ten years is a testament to the fund’s two advisors and their efforts to identify companies that are undergoing short-term challenges yet have superior prospects for long-term growth.

In addition to its expert advisors, the fund’s superior performance over the period is made possible by the fund’s low costs.

A diversified portfolio is key in up and down markets
Although the fund’s 2010 fiscal year ended on a high note, it’s impossible to predict the market’s direction down the road. Seasoned investors understand that coping with the stock market’s ups and downs is an integral part of investing. An inescapable, if unpleasant, reality of investing is that to reap the potential for higher rewards, you must learn to live with greater risks.

Our experience suggests that an effective way to cope with market uncertainty is for investors to focus on the long term and build a diversified, well-balanced portfolio. A portfolio with a mix of stock, bond, and short-term investments can help protect your assets from the markets’ worst outcomes while giving you the opportunity to participate in the best. Investing within and among asset classes can further enhance your diversification.

Vanguard Windsor Fund, with its low costs and talented advisory team, can play an important supporting role in such a balanced portfolio.

Thank you for entrusting your assets to Vanguard.

Sincerely,

F. William McNabb III

Advisors’ Report

For the fiscal year ended October 31, 2010, the Investor Shares of Vanguard Windsor Fund returned 16.31%, while the lower-cost Admiral Shares returned 16.44%. Your fund is managed by two independent advisors, a strategy that enhances the fund’s diversification by providing exposure to distinct, yet complementary, investment approaches. It is not uncommon for different advisors to have different views about individual securities or the broader investment environment.

The advisors, the percentage and amount of fund assets that each manages, and brief descriptions of their investment strategies are presented in the table below. The advisors have also prepared a discussion of the investment environment that existed during the period and of how the portfolio positioning reflects this assessment. These reports were prepared on November 16, 2010.

Wellington Management Company, llp

Portfolio Manager:

James N. Mordy, Senior Vice President and Equity Portfolio Manager Over the past year, our portfolio has held up reasonably well during a period of high market volatility. After a strong run earlier in the period, the S&P 500 peaked in April and then fell about 18% over the next ten weeks as economic momentum stalled and fears of a double dip increased. A vigorous rally then ensued on more encouraging economic data, anticipation of another round of quantitative easing, and the prospects for a change in control of Congress. We have largely maintained an overweighting to some of the more cyclical sectors of the market, which, with the exception of energy and financials, have led the market advance. At the end of the fiscal year, 77% of our portfolio was invested in these sectors (energy, materials, consumer discretionary, information technology, financials, and industrials), which together account for about 71% of the capitalization of the S&P 500 Ind ex and 64% of the Russell 1000 Value Index.

Our best-performing sector for the year was industrials, which was our worst sector last year. Delta Air Lines stock soared as corporate travel demand recovered and the major carriers showed discipline in controlling capacity. Absent a terrorist attack or a sudden spike in oil prices, we believe Delta is now in a period of strong profit recovery. We also notched strong gains in other industrials, such as Deere, Boeing, and Dover.

Despite a challenging environment in terms of high unemployment and an increase in the savings rate, consumers modestly increased spending and consumer discretionary has been the strongest sector of the market over the past 12 months. We were well-positioned as this is our largest overweighting. Highlights included Buck Holdings, which represents the stake we took in Dollar General when that retailer was privatized. Our cable and media holdings also benefited from strong fundamentals and a rebound in advertising spending.

Energy, health care, and materials also provided positive relative performance versus the S&P 500. We underperformed in the technology sector, partly because we don’t own Apple (which is more than 2% of the index’s capitalization), and partly because some of the larger-capitalization names we do own—such as Cisco and Hewlett-Packard—lagged. Another challenging sector was consumer staples, where we made a mistake with leading dairy processor Dean Foods. We underestimated the squeeze on margins from unusually promotional milk pricing by large grocers. In financials, our stocks did only slightly better than the group average. Financials was the worst-performing sector of the S&P 500 and our overweighting of it created a bit of a headwind.

8

During the year, we were net buyers (in order of significance) in the consumer staples, financial, IT, and utility sectors.

We were net sellers in the energy, industrial, consumer discretionary, materials, and health care sectors. Among our largest purchases were Anadarko Petroleum (which was attractive even allowing for significant liability as BP’s 25% partner in the Macondo well); Qualcomm (where sentiment and valuation had sunk after a couple of disappointing quarters, which we viewed as temporary given the company’s strong position in the smart phone market); and additions to our sizable Wells Fargo holding (which we don’t think is getting enough credit for its robust earnings power and lower exposure to mortgage losses compared with some of its peers among the major U.S. banks). Our sector positioning has changed only marginally over the past six months. We reduced industrials to slightly underweight from overweight, and increased our overweighting in materials. Our largest overweighted positions versus the S&P 500 Index remain in financials, consumer di scretionary, and materials. Our largest underweighted positions remain in consumer staples, IT, and telecommunication services.

We continue to see a subdued recovery. Key developments supporting the recovery include decent retail sales, stronger October auto sales, a pickup in the PMI index, a soft landing in China (versus earlier fears of a sharper slowdown), an acceleration in money supply growth,

better equity markets, and a second installment of quantitative easing by the Federal Reserve, which have helped sustain low interest rates and reduced the odds of a double-dip recession. Employment growth is a critical factor that has yet to kick in, though we did see some better numbers in the October report. Further improvement in the employment situation depends on business confidence, which might improve as a result of the midterm election. We are conscious of near-term headwinds as the GDP’s benefit from inventory restocking has largely played out, fiscal restraint seems to be the new mantra in Washington, and any failure to extend the Bush tax cuts before year end will result in higher payroll deductions in early 2011.

Corporations have been able to refinance at low rates and generate record amounts of free cash flow thanks to a historic retrenchment in capital spending. While capital spending is now increasing, we also anticipate a significant amount of merger and acquisition activity in the coming year as corporate managers consider more productive uses for their ample cash balances.

We will remain true to our time-tested value investing principles. Based on consensus analyst expectations, our stocks continue to sell at a discount to the P/E of both the S&P 500 and the Russell 1000 Value Indexes, and have slightly better earnings growth prospects over the next

five years. It is classic Windsor math to own companies at discounted valuations that have the potential of producing superior returns over the long run.

Portfolio Managers:

Joseph G. Paul, Chief Investment Officer of North American Value Equities and Co-Chief Investment Officer of U.S. Large-Cap Value Equities Gregory L. Powell, Portfolio Manager Deep uncertainty among investors has driven the stampede into safe assets over the past year. But while fears of another economic and market slump are understandable, we think investors are underestimating the cost of playing it safe—and the far greater potential for higher returns in equities. Stocks are not only extraordinarily attractive versus bonds; they are also historically cheap, even based on cyclically depressed near-term earnings outlooks.

There is also a big opportunity to add value through stock-picking. With macro worries dominating, investors are ignoring important differences in fundamentals and valuations among companies. The spike in risk aversion this spring and late summer was particularly hard on the portfolio’s performance. But this environment has also led many company stocks to be undervalued and we believe our research-driven value strategy is well-equipped to exploit the opportunities created. Indeed, the valuation spread between the cheapest and most expensive stocks remains well above the historical average, implying significant outperformance potential.

Our portfolio is strongly positioned to take advantage of the compelling value opportunity we see in free cash flows. Investors are reluctant to assign much value to excess cash, reflecting doubts that it can be deployed productively. But our research shows that the corporate cash giveback potential is as great as it has ever been and should drive strong stock gains as managements unlock this value via buybacks, dividends, and acquisitions. We expect holdings as diverse as Garmin, Sara Lee, Gap, and AstraZeneca to generate long-term free cash flows ranging from 50% to 90% of their current stock prices, yet they are trading well below the value benchmark, based on our long-term earnings forecasts.

Additions to our holdings include two leading North American nitrogen-fertilizer producers, Agrium and CF Industries. Our research indicates that the market is underestimating these two companies’ long-term earnings potential resulting from the recent surge in grain prices—which has boosted farmer income and should drive much higher demand for fertilizer—

10

and from the continued price weakness in U.S. natural gas, a major cost input for making nitrogen fertilizer. These savings give the two companies a huge advantage over global competitors, particularly in China and the Ukraine, which depend on more expensive natural gas and coal.

We also recently initiated positions in Marathon Oil and Hess. The stocks have lagged because investors are, in our view, excessively extrapolating weak recent results, which were weighed down by investments that we expect to now begin paying off.

History shows that fundamentals and low valuations drive value stocks over time. As the market’s fixation on macro concerns abates, we are confident that the portfolio can realize its latent potential.

Windsor Fund

Notes to Financial Statements

Vanguard Windsor Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Investor Shares and Admiral Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, service, and account-size criteria.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4 p.m., Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued at their fair values calculated according to procedures adopted by the board of trustees. These procedures include obtaining quotations from an independent pricing service, monitoring news to identify significant market- or security-specific events, and evaluating changes in the values of foreign market proxies (for example, ADRs, futures contracts, or exchange-traded funds), between the time the foreign markets close and the fund’s pricing time. When fair-value pricing is employed, the prices of securities used by a fund to calculate its net asset value may differ from quoted or published prices for the same securities. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

2. Foreign Currency: Securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars using exchange rates obtained from an independent third party as of the fund’s pricing time on the valuation date. Realized gains (losses) and unrealized appreciation (depreciation) on investment securities include the effects of changes in exchange rates since the securities were purchased, combined with the effects of changes in security prices. Fluctuations in the value of other assets and liabilities resulting from changes in exchange rates are recorded as unrealized foreign currency gains (losses) until the assets or liabilities are settled in cash, at which time they are recorded as realized foreign currency gains (losses).

3. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objective of maintaining full exposure to the stock market while maintaining liquidity. The fund may purchase or sell futures contracts to achieve a desired level of investment, whether to accommodate portfolio turnover or cash flows from capital share transactions. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

Futures contracts are valued at their quoted daily settlement prices. The aggregate principal amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

4. Repurchase Agreements: The fund invests in repurchase agreements. Securities pledged as collateral for repurchase agreements are held by a custodian bank until the agreements mature. Each agreement requires that the market value of the collateral be sufficient to cover payments of interest and principal; however, in the event of default or bankruptcy by the other party to the agreement, retention of the collateral may be subject to legal proceedings.

5. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for all open federal income tax years (October 31, 2007–2010), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

6. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

7. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents fees charged to borrowers plus income earned on investing cash collateral, less expenses associated with the loan.

8. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. AllianceBernstein L.P. and Wellington Management Company, LLP, each provide investment advisory services to a portion of the fund for a fee calculated at an annual percentage rate of average net assets managed by the advisor. The basic fees of each advisor are subject to quarterly adjustments based on performance for the preceding three years relative to a designated market index: for AllianceBernstein L.P., the Russell 1000 Value Index; and for Wellington Management Company, LLP, the S&P 500 Index.

The Vanguard Group manages the cash reserves of the fund on an at-cost basis.

For the year ended October 31, 2010, the aggregate investment advisory fee represented an effective annual basic rate of 0.13% of the fund’s average net assets, before a decrease of $3,830,000 (0.03%) based on performance.

C. The Vanguard Group furnishes at cost corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At October 31, 2010, the fund had contributed capital of $2,202,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 0.88% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

24

Windsor Fund

D. The fund has asked its investment advisors to direct certain security trades, subject to obtaining the best price and execution, to brokers who have agreed to rebate to the fund part of the commissions generated. Such rebates are used solely to reduce the fund’s management and administrative expenses. For the year ended October 31, 2010, these arrangements reduced the fund’s expenses by $640,000 (an annual rate of 0.01% of average net assets).

E. Various inputs may be used to determine the value of the fund’s investments. These inputs are summarized in three broad levels for financial statement purposes. The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

Level 1—Quoted prices in active markets for identical securities.
Level 2—Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).
Level 3—Significant unobservable inputs (including the fund’s own assumptions used to determine the fair value of investments).

The following table summarizes the fund’s investments as of October 31, 2010, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	11,724,058	572,113	206,299
Temporary Cash Investments	111,434	101,381	—

F. At October 31, 2010, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:

				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
S&P 500 Index	December 2010	154	45,418	2,459
E-mini S&P MidCap 400 Index	December 2010	337	27,887	1,630

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

G. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the year ended October 31, 2010, the fund realized net foreign currency losses of $71,000, which decreased distributable net income for tax purposes; accordingly, such losses have been reclassified from accumulated net realized losses to undistributed net investment income.

For tax purposes, at October 31, 2010, the fund had $49,712,000 of ordinary income available for distribution. The fund had available capital loss carryforwards totaling $4,497,216,000 to offset future net capital gains of $2,266,771,000 through October 31, 2016, and $2,230,445,000 through October 31, 2017.

At October 31, 2010, the cost of investment securities for tax purposes was $11,179,352,000. Net unrealized appreciation of investment securities for tax purposes was $1,535,933,000, consisting of unrealized gains of $2,020,947,000 on securities that had risen in value since their purchase and $485,014,000 in unrealized losses on securities that had fallen in value since their purchase.

H. During the year ended October 31, 2010, the fund purchased $6,064,824,000 of investment securities and sold $6,786,232,000 of investment securities, other than temporary cash investments.

Report of Independent Registered Public Accounting Firm

To the Trustees of Vanguard Windsor Funds and the Shareholders of Vanguard Windsor Fund:

In our opinion, the accompanying statement of net assets, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Windsor Fund (constituting a separate portfolio of Vanguard Windsor Funds, hereafter referred to as the “Fund”) at October 31, 2010, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audit s of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at October 31, 2010 by correspondence with the custodians and brokers and by agreement to the underlying ownership records of Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

Special 2010 tax information (unaudited) for Vanguard Windsor Fund 

This information for the fiscal year ended October 31, 2010, is included pursuant to provisions of the Internal Revenue Code. 

The fund distributed $202,543,000 of qualified dividend income to shareholders during the fiscal year. 

For corporate shareholders, 100% of investment income (dividend income plus short-term gains, if any) 

qualifies for the dividends-received deduction.

Your Fund’s After-Tax Returns

This table presents returns for your fund both before and after taxes. The after-tax returns are shown in two ways: (1) assuming that an investor owned the fund during the entire period and paid taxes on the fund’s distributions, and (2) assuming that an investor paid taxes on the fund’s distributions and sold all shares at the end of each period.

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect any qualified dividend income , using actual prior-year figures and estimates for 2010. (In the example, returns after the sale of fund shares may be higher than those assuming no sale. This occurs when the sale would have produced a capital loss. The calculation assumes that the investor received a tax deduction for the loss.) The table shows returns for Investor Shares only; returns for other share classes will differ. Please note that your actual after-tax returns will depend on your tax situation and may differ from those shown. Also note that if you own the fund in a tax-deferred account, such as an individual retirement account or a 401(k) plan, this information does not apply to you. Such accounts are not subject to c urrent taxes.

Finally, keep in mind that a fund’s performance—whether before or after taxes—does not guarantee future results.

Average Annual Total Returns: Windsor Fund Investor Shares
Periods Ended October 31, 2010
	One	Five	Ten
	Year	Years	Years
Returns Before Taxes	16.31%	0.55%	3.28%
Returns After Taxes on Distributions	16.04	-0.62	2.20
Returns After Taxes on Distributions and Sale of Fund Shares	10.93	0.48	2.63

About Your Fund’s Expenses

As a shareholder of the fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund’s gross income, directly reduce the investment return of the fund.

A fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period.

The accompanying table illustrates your fund’s costs in two ways:

• Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The ”Ending Account Value“ shown is derived from the fund‘s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period.

To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading ”Expenses Paid During Period.“

• Based on hypothetical 5% yearly return. This section is intended to help you compare your fund‘s costs with those of other mutual funds. It assumes that the fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case—because the return used is not the fund’s actual return—the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund’s costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

Note that the expenses shown in the table are meant to highlight and help you compare ongoing costs only and do not reflect transaction costs incurred by the fund for buying and selling securities. Further, the expenses do not include the transaction fees or the account service fee described in the prospectus. If such fees were applied to your account, your costs would be higher. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it carry a “sales load.” The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions.

You can find more information about the fund’s expenses, including annual expense ratios, in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to your fund’s current prospectus.

Six Months Ended October 31, 2010
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
Windsor Fund	4/30/2010	10/31/2010	Period
Based on Actual Fund Return
Investor Shares	$1,000.00	$984.48	$1.55
Admiral Shares	1,000.00	984.68	1.15
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,023.64	$1.58
Admiral Shares	1,000.00	1,024.05	1.17

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that period are 0.31% for Investor Shares and 0.23% for Admiral Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Glossary

30-Day SEC Yield. A fund’s 30-day SEC yield is derived using a formula specified by the U.S. Securities and Exchange Commission. Under the formula, data related to the fund’s security holdings in the previous 30 days are used to calculate the fund’s hypothetical net income for that period, which is then annualized and divided by the fund’s estimated average net assets over the calculation period. For the purposes of this calculation, a security’s income is based on its current market yield to maturity (in the case of bonds) or its projected dividend yield (for stocks). Because the SEC yield represents hypothetical annualized income, it will differ—at times significantly—from the fund’s actual experience. As a result, the fund’s income distributions may be higher or lower than implied by the SEC yield.

Beta. A measure of the magnitude of a fund’s past share-price fluctuations in relation to the ups and downs of a given market index. The index is assigned a beta of 1.00. Compared with a given index, a fund with a beta of 1.20 typically would have seen its share price rise or fall by 12% when the index rose or fell by 10%. For this report, beta is based on returns over the past 36 months for both the fund and the index. Note that a fund’s beta should be reviewed in conjunction with its R-squared (see definition). The lower the R-squared, the less correlation there is between the fund and the index, and the less reliable beta is as an indicator of volatility.

Dividend Yield. Dividend income earned by stocks, expressed as a percentage of the aggregate market value (or of net asset value, for a fund). The yield is determined by dividing the amount of the annual dividends by the aggregate value (or net asset value) at the end of the period. For a fund, the dividend yield is based solely on stock holdings and does not include any income produced by other investments.

Earnings Growth Rate. The average annual rate of growth in earnings over the past five years for the stocks now in a fund.

Equity Exposure. A measure that reflects a fund’s investments in stocks and stock futures. Any holdings in short-term reserves are excluded.

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

Foreign Holdings. The percentage of a fund represented by stocks or depositary receipts of companies based outside the United States.

Inception Date. The date on which the assets of a fund (or one of its share classes) are first invested in accordance with the fund’s investment objective. For funds with a subscription period, the inception date is the day after that period ends. Investment performance is measured from the inception date.

Median Market Cap. An indicator of the size of companies in which a fund invests; the midpoint of market capitalization (market price x shares outstanding) of a fund’s stocks, weighted by the proportion of the fund’s assets invested in each stock. Stocks representing half of the fund’s assets have market capitalizations above the median, and the rest are below it.

Price/Book Ratio. The share price of a stock divided by its net worth, or book value, per share. For a fund, the weighted average price/book ratio of the stocks it holds.

32

Price/Earnings Ratio. The ratio of a stock’s current price to its per-share earnings over the past year. For a fund, the weighted average P/E of the stocks it holds. P/E is an indicator of market expectations about corporate prospects; the higher the P/E, the greater the expectations for a company’s future growth.

R-Squared. A measure of how much of a fund’s past returns can be explained by the returns from the market in general, as measured by a given index. If a fund’s total returns were precisely synchronized with an index’s returns, its R-squared would be 1.00. If the fund’s returns bore no relationship to the index’s returns, its R-squared would be 0. For this report, R-squared is based on returns over the past 36 months for both the fund and the index.

Return on Equity. The annual average rate of return generated by a company during the past five years for each dollar of shareholder’s equity (net income divided by shareholder’s equity). For a fund, the weighted average return on equity for the companies whose stocks it holds.

Short-Term Reserves. The percentage of a fund invested in highly liquid, short-term securities that can be readily converted to cash.

Turnover Rate. An indication of the fund’s trading activity. Funds with high turnover rates incur higher transaction costs and may be more likely to distribute capital gains (which may be taxable to investors). The turnover rate excludes in-kind transactions, which have minimal impact on costs.

The People Who Govern Your Fund

The trustees of your mutual fund are there to see that the fund is operated and managed in your best interests since, as a shareholder, you are a part owner of the fund. Your fund’s trustees also serve on the board of directors of The Vanguard Group, Inc., which is owned by the Vanguard funds and provides services to them on an at-cost basis.

A majority of Vanguard’s board members are independent, meaning that they have no affiliation with Vanguard or the funds they oversee, apart from the sizable personal investments they have made as private individuals. The independent board members have distinguished backgrounds in business, academia, and public service. Each of the trustees and executive officers oversees 178 Vanguard funds.

The following table provides information for each trustee and executive officer of the fund. More information about the trustees is in the Statement of Additional Information, which can be obtained, without charge, by contacting Vanguard at 800-662-7447, or online at vanguard.com.

Chairman’s Letter

Dear Shareholder,

Vanguard Windsor II Fund turned in strong results for the fiscal year ended October 31, 2010, returning about 12%. Still, the fund fell several points behind its benchmark, the Russell 1000 Value Index, which returned almost 16%. The fund’s return was also slightly lower than the average return for large-cap value funds for the period.

The fund posted positive results in all ten market sectors, benefiting in particular from its holdings in consumer discretionary and industrials. However, poor stock selection in some areas—most notably information technology—hindered the fund’s performance relative to its index.

Please note that on October 6 Vanguard broadened the availability of our lower-cost Admiral Shares. We reduced the Admiral minimums on most of our actively managed funds to $50,000 from $100,000, as part of our ongoing efforts to lower the cost of investing for our clients.

If you hold shares in a taxable account, you may wish to review the table and discussion on after-tax returns for the fiscal year later in this report.

Stock market performance was better than it felt
Global stock prices rallied at the start of the period but struggled through the spring and summer, weighed down by Europe’s sovereign debt crisis and the slow pace of economic recovery in the United States. In the fiscal year’s final months, the mood

turned. Stock prices climbed on continued strength in corporate earnings. In the United States, stocks also seemed to get a boost from the Federal Reserve Board’s hints that it would try to stimulate the economy with a second round of U.S. Treasury bond purchases. (In early November, the Fed announced that it would buy as much as $600 billion in Treasuries.)

For the 12 months, the broad U.S. stock market returned about 19%, a performance that was stronger than it felt in a year of ups and downs. Small-capitalization stocks did even better. International stocks returned about 13% on the strength of a powerful rally in emerging markets and solid single-digit gains in developed markets in Europe and the Pacific region.

Despite shrinking yields, bonds attracted investor dollars
Although fixed income yields fell to generational lows, investors continued to bid up bond prices. The broad U.S. bond market produced a 12-month return of about 8% as the yield of the 10-year U.S. Treasury note fell from 3.39% at the start of the period to 2.61% at the close. Tax-exempt municipal bonds also rallied. Bond prices and yields move in opposite directions, of course, so abundant returns built on rising prices could mean leaner pickings in the years ahead.

The yields of money market securities hovered near 0%, consistent with the Federal Reserve Board’s target for short-term rates.

approach, which includes both fundamental and quantitative techniques, adds diversification to the portfolio. While the fund’s six advisors have individual styles, the overall focus is on stocks with below-average price/earnings ratios and above-average yields.

For the fiscal year, the fund posted positive results in all ten market sectors. The largest contributors to performance included stocks in the consumer discretionary and industrial sectors, as both benefited from a strengthening U.S. economy. Improved

Fund misses its mark despite solid returns
Vanguard Windsor II Fund invests in a broad mix of large- and mid-capitalization value stocks. The fund’s multimanager consumer confidence helped boost consumer stocks across the board, including holdings in media companies, auto manufacturers, and retailers. In industrials, equipment and machinery companies rose on high demand in emerging markets, most notably China.

The advisors’ stock selection in some other sectors hindered the fund’s performance relative to its benchmark. This effect was most notable in information technology. Nokia, which failed to keep up in the fast-paced cell phone market and saw its stock drop 12%, was among the fund’s weakest performers. Microsoft, considered to be “behind the times” in comparison with its rival Apple, was also down for the period.

The fund’s significant allocation to the tech sector also subtracted from performance relative to the index. In recent years, this sector—whose stocks don’t typically qualify as “value” holdings and therefore have little representation in the Russell 1000 Value Index—has become a large holding for the fund. During the period, tech stocks accounted for about 16% of the fund’s holdings, on average, while the sector made up only about 5% of the index.

Stock selection in health care equipment and providers detracted from returns as well. In the energy sector, the fund was hurt by its significant holdings in BP at the time of the oil spill in the Gulf. Although the fund has since trimmed its exposure to the oil giant, the stock weighed on performance relative to the index, which holds only U.S. firms and so had zero exposure to the company.

In telecommunication services, the fund had modest investments in Verizon and AT&T and largely missed out on their gains; both companies shared in the continued success of smartphones during the period.

The fund did distinguish itself in a few sectors, most notably within financials and materials. For example, the portfolio had a stake in American Express, which benefited from improved optimism about consumer spending. The fund also limited its allocation to some of the hardest-hit

companies in financials, including Citigroup, Bank of America, and Goldman Sachs. In materials, chemical and container companies helped boost returns.

Solid long-term results amid difficult times
Despite lagging its benchmark for the 12-month period, the Windsor II Fund continued to outperform over the long term. For the ten years ended October 31, Investor Shares of Vanguard Windsor II Fund had an average annual return of 3.41%, beating the fund’s benchmark index (2.64%) and its large-cap value fund peers (0.64%).

At first glance, the fund’s ten-year performance may not appear all that impressive. However, these returns reflect a decade in which the stock market endured two steep downturns, not to mention the deepest recession since the Great Depression. Over the period, the fund surpassed the broad U.S. stock market, which returned an average of 1.02% per year.

The Windsor II Fund’s solid long-term performance is a tribute to its advisors. The fund’s longest-serving advisor, Jim Barrow, has managed the fund since its 1985 inception, delivering a quarter-century of distinguished service to shareholders. Windsor II Fund’s combination of talented investment managers and low costs remains as compelling today as when it first began operations 25 years ago.

Regardless of market conditions, stay focused on the future
The ups and downs of the stock market seem all too familiar these days. While this can be nerve-wracking, it’s also a good reminder that you shouldn’t let such unpredictability unduly influence your long-term investment strategy.

Vanguard encourages you to create a plan that includes a mix of stocks, bonds, and short-term investments appropriate for your goals and risk tolerance—and to stick with that plan, regardless of market conditions.

A well-balanced portfolio can help cushion some of the market’s downward swings while allowing you to participate in its long-term potential for growth. With its low costs and broad diversification among large- and mid-cap value stocks, Vanguard’s Windsor II Fund can play an important role in such an investment plan.

Thank you for entrusting your assets to Vanguard.

Sincerely,

F. William McNabb III

Barrow, Hanley, Mewhinney & Strauss, LLC

Portfolio Manager:

James P. Barrow, Founding Partner

Investment environment: The equity market spent most of the fiscal year in a modest decline. In late August, when it looked as if there would be no double-dip recession, the market took off.

Successes: Consumer discretionary names generally did well for the period, and our “sin stocks” were strong performers.

Shortfalls: We had some bad luck with unforeseen problems with BP and Hewlett-Packard. Foreclosure difficulties and mortgage origination suits bedeviled the banks’ recovery.

For the most part, the underperforming investments seem on the mend to the point that we would add to them in the expectation of a complete fundamental recovery. Since the end of the fiscal year, it looks as if some of the holdings that suspended dividend payments will soon reinstate them.

Lazard Asset Management LLC

Portfolio Managers:

Andrew Lacey, Deputy Chairman Christopher Blake, Managing Director

Investment environment: Despite the extremely volatile year, U.S. equity markets rose overall amid signs of continuing recovery in the global economy and solid corporate earnings results. Over the past year, more cyclical sectors, such as consumer discretionary and industrials, performed well. Telecom services also gained, as the market continued to invest in smartphone adoption and looked for dividend yield. Financials was the worst-performing sector, as investors tried to gauge bank profitability and the effects of increased government regulation.

Successes: During the year, stock selection in the energy and consumer discretionary sectors added to returns. In energy, ConocoPhillips performed well. The U.S. integrated energy company shifted its focus to debt reduction, raised its dividend, and generated strong production growth. In consumer discretionary, shares of AutoZone, a leading auto parts retailer, climbed as the company reported a series of strong quarterly earnings.

Shortfalls: Stock selection in the consumer staples and technology sectors detracted from returns. In consumer staples, shares of Walgreen declined as the U.S. drug-store chain experienced headwinds to earnings growth. In technology, shares of Symantec fell because of various product execution issues. However, we believe the recurring cash flow streams for maintenance and subscriptions remain undervalued.

Sanders Capital, LLC

Portfolio Managers: Lewis A. Sanders, CFA

Chief Executive Officer and Co-Chief Investment Officer John P. Mahedy, CPA

Director of Research and Co-Chief Investment Officer

Investment environment: Excessive public and private debt is widely believed to portend an extended period of subpar economic growth. We disagree. The remediation of balance sheets in the corporate and financial sectors is nearly complete. Very low interest rates, especially for home mortgages, have also greatly improved the debt service position of households, a process that is ongoing. Thus, the preconditions for faster economic growth are gradually falling into place.

Successes: Our portfolio is positioned to benefit from these trends, with investments in the technology, energy, banking, and insurance industries. Our investments in the health care and consumer staples sectors bring balance to this pro-cyclical exposure.

Shortfalls: We anticipate that financial strength, which characterizes all of our holdings, will be a favorable attribute as well, in contrast to the superior performance of leveraged companies in the recent past.

Hotchkis and Wiley Capital Management, LLC

Portfolio Managers: George H. Davis, Jr., Chief Executive Officer Sheldon J. Lieberman, Principal

Investment environment: Recent corporate performance has been particularly resilient, largely as a result of the operating leverage created by aggressive cost-cutting during and after the recession. Profit margins and free cash flow margins are near all-time highs. Balance sheets are as pristine as they have been in recent memory. A liquidity release could take several forms, most of which should benefit common equity holders. Currently, the largest risk we see is political; the passage of counterproductive anti-business legislation is always a concern. Nevertheless, valuations and fundamentals both remain compelling for the astute value investor.

Successes: The portfolio performed strongly over the past 12 months because of positive stock selection, particularly in industrials and energy. Cummins, Tyco Electronics, and Limited Brands were the top individual contributors.

Shortfalls: Performance suffered primarily because of stock selection in electric utilities. Exelon was the biggest detractor.

9

Armstrong Shaw Associates Inc.

Portfolio Manager:

Jeffrey M. Shaw, Chairman and Chief Investment Officer

Investment environment: The past year was marked by extreme volatility as the market reacted to macro concerns about the sovereign credit crisis, unemployment, deflation, and the deficit. Still, the risk of a double dip has lessened as the Fed implements policies to fight deflation, and corporate earnings news has been better than expected. That said, the economic recovery remains weak. We continue to believe that we will see a recovery led by corporate profits, not driven by consumers. The portfolio’s overweight positions in technology, industrials, and energy and underweight positions in consumer-oriented sectors reflect this view. We have no exposure to telecom or utilities, given that we see better opportunities elsewhere.

Successes: Our best-performing sector was materials (47%), followed by consumer discretionary (32%) and industrials (23%). Agrium, a materials holding, was our top performer, up 82% on strong earnings, rising commodity prices, and BHP’s bid for Potash Corp.

Shortfalls: Consumer staples was our worst sector, down 9%. CVS fell 14% as the company engaged in a contentious public contract negotiation with Walgreens, which has since been resolved.

Vanguard Quantitative Equity Group

Portfolio Manager:

James D. Troyer, CFA, Principal

Investment environment: The investment environment remained volatile during the year. A strong first half foundered on the European debt crisis and then concerns over future U.S. growth. The Federal Reserve’s quantitative easing program kicked off a strong final two months. Broad, macro themes have been dominating investor behavior, causing rapid swings in returns. Value-oriented stocks in the index lagged growth stocks slightly, while large-capitalization names underperformed smaller-cap companies.

Successes: Our quantitative process was largely successful for the period. Our valuation, market sentiment, and management decision models had positive results.

Shortfalls: Our earnings growth and quality models lagged the market.

Windsor II Fund

Notes to Financial Statements

Vanguard Windsor II Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Investor Shares and Admiral Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, service, and account-size criteria.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4 p.m., Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued at their fair values calculated according to procedures adopted by the board of trustees. These procedures include obtaining quotations from an independent pricing service, monitoring news to identify significant market- or security-specific events, and evaluating changes in the values of foreign market proxies (for example, ADRs, futures contracts, or exchange-traded funds), between the time the foreign markets close and the fund’s pricing time. When fair-value pricing is employed, the prices of securities used by a fund to calculate its net asset value may differ from quoted or published prices for the same securities. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

2. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objective of maintaining full exposure to the stock market while maintaining liquidity. The fund may purchase or sell futures contracts to achieve a desired level of investment, whether to accommodate portfolio turnover or cash flows from capital share transactions. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

Futures contracts are valued at their quoted daily settlement prices. The aggregate principal amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Management has analyzed the fund’s tax positions taken for all open federal income tax years (October 31, 2007–2010), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

5. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market

23

Windsor II Fund

Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents fees charged to borrowers plus income earned on investing cash collateral, less expenses associated with the loan.

6. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. Barrow, Hanley, Mewhinney & Strauss, LLC; Lazard Asset Management LLC; Hotchkis and Wiley Capital Management, LLC; Armstrong Shaw Associates Inc.; and beginning in January 2010, Sanders Capital, LLC, each provide investment advisory services to a portion of the fund for a fee calculated at an annual percentage rate of average net assets managed by the advisor. The basic fee of Barrow, Hanley, Mewhinney & Strauss, LLC, is subject to quarterly adjustments based on performance for the preceding three years relative to the MSCI US Prime Market 750 Index. The basic fee of Lazard Asset Management LLC is subject to quarterly adjustments based on performance for the preceding three years relative to the S&P 500 Index. The basic fee of Hotchkis and Wiley Capital Management, LLC, is subject to quarterly adjustments based on performance for the preceding five years relative to the MSCI US Investable Market 2500 Index. The basic fee of Armstrong Shaw Associates Inc. is subject to quarterly adjustments based on performance since January 31, 2006, relative to the Russell 1000 Value Index. In accordance with the advisory contract entered into with Sanders Capital, LLC, in January 2010, beginning November 1, 2010, the investment advisory fee will be subject to quarterly adjustments based on performance since January 31, 2010, relative to the Russell 3000 Index.

The Vanguard Group provides investment advisory services to a portion of the fund on an at-cost basis; the fund paid Vanguard advisory fees of $147,000 for the year ended October 31, 2010.

For the year ended October 31, 2010, the aggregate investment advisory fee represented an effective annual basic rate of 0.15% of the fund’s average net assets, before a decrease of $4,126,000 (0.01%) based on performance.

C. The Vanguard Group furnishes at cost corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At October 31, 2010, the fund had contributed capital of $6,018,000 to Vanguard (included in Other Assets), representing 0.02% of the fund’s net assets and 2.41% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

D. The fund has asked its investment advisors to direct certain security trades, subject to obtaining the best price and execution, to brokers who have agreed to rebate to the fund part of the commissions generated. Such rebates are used solely to reduce the fund’s management and administrative expenses. For the year ended October 31, 2010, these arrangements reduced the fund’s expenses by $1,589,000 (an annual rate of 0.00% of average net assets).

E. Various inputs may be used to determine the value of the fund’s investments. These inputs are summarized in three broad levels for financial statement purposes. The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

Level 1—Quoted prices in active markets for identical securities.
Level 2—Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).
Level 3—Significant unobservable inputs (including the fund’s own assumptions used to determine the fair value of investments).

The following table summarizes the fund’s investments as of October 31, 2010, based on the inputs used to value them:

	Level 1	Level 2	Level 3
Investments	($000)	($000)	($000)
Common Stocks	33,412,327	—	—
Temporary Cash Investments	932,091	70,038	—
Futures Contracts—Assets1	147	—	—
Total	34,344,565	70,038	—
1 Represents variation margin on the last day of the reporting period.

The following table summarizes changes in investments valued based on Level 3 inputs during the year ended October 31, 2010:

	Investments in
	Common Stocks
Amount Valued Based on Level 3 Inputs	($000)
Balance as of October 31, 2009	59
Transfers out of Level 3	(59)
Balance as of October 31, 2010	—

F. At October 31, 2010, the aggregate settlement value of open futures contracts and the related unrealized appreciation (depreciation) were:

				($000)
			Aggregate
		Number of	Settlement	Unrealized
		Long (Short)	Value	Appreciation
Futures Contracts	Expiration	Contracts	Long (Short)	(Depreciation)
E-mini S&P 500 Index	December 2010	6,505	383,697	3,713
S&P 500 Index	December 2010	166	48,958	2,651

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

G. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences are primarily attributed to tax deferral of losses on wash sales and will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

For tax purposes, at October 31, 2010, the fund had $214,041,000 of ordinary income available for distribution. The fund had available capital loss carryforwards totaling $5,197,281,000 to offset future net capital gains of $3,383,640,000 through October 31, 2016, $1,639,579,000 through October 31, 2017, and $174,062,000 through October 31, 2018.

At October 31, 2010, the cost of investment securities for tax purposes was $31,484,652,000. Net unrealized appreciation of investment securities for tax purposes was $2,929,804,000, consisting of unrealized gains of $6,927,497,000 on securities that had risen in value since their purchase and $3,997,693,000 in unrealized losses on securities that had fallen in value since their purchase.

H. During the year ended October 31, 2010, the fund purchased $9,568,406,000 of investment securities and sold $10,372,065,000 of investment securities, other than temporary cash investments.

I. Capital share transactions for each class of shares were:

Report of Independent Registered Public Accounting Firm

To the Trustees of Vanguard Windsor Funds and the Shareholders of Vanguard Windsor II Fund: In our opinion, the accompanying statement of net assets and statement of assets and liabilities, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Windsor II Fund (constituting a separate portfolio of Vanguard Windsor Funds, hereafter referred to as the “Fund”) at October 31, 2010, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund&# 146;s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at October 31, 2010 by correspondence with the custodian and broker and by agreement to the underlying ownership records of Vanguard Market Liquidity Fund, provide a reasonable basis for our opinion.

Special 2010 tax information (unaudited) for Vanguard Windsor II Fund 

This information for the fiscal year ended October 31, 2010, is included pursuant to provisions of the Internal Revenue Code. 

The fund distributed $736,882,000 of qualified dividend income to shareholders during the fiscal year. 

For corporate shareholders, 97.0% of investment income (dividend income plus short-term gains, if any) 

qualifies for the dividends-received deduction.

Your Fund’s After-Tax Returns

This table presents returns for your fund both before and after taxes. The after-tax returns are shown in two ways: (1) assuming that an investor owned the fund during the entire period and paid taxes on the fund’s distributions, and (2) assuming that an investor paid taxes on the fund’s distributions and sold all shares at the end of each period.

Calculations are based on the highest individual federal income tax and capital gains tax rates in effect at the times of the distributions and the hypothetical sales. State and local taxes were not considered. After-tax returns reflect any qualified dividend income , using actual prior-year figures and estimates for 2010. (In the example, returns after the sale of fund shares may be higher than those assuming no sale. This occurs when the sale would have produced a capital loss. The calculation assumes that the investor received a tax deduction for the loss.) The table shows returns for Investor Shares only; returns for other share classes will differ. Please note that your actual after-tax returns will depend on your tax situation and may differ from those shown. Also note that if you own the fund in a tax-deferred account, such as an individual retirement account or a 401(k) plan, this information does not apply to you. Such accounts are not subject to c urrent taxes.

Finally, keep in mind that a fund’s performance—whether before or after taxes—does not guarantee future results.

Average Annual Total Returns: Windsor II Fund Investor Shares
Periods Ended October 31, 2010
	One	Five	Ten
	Year	Years	Years
Returns Before Taxes	12.05%	0.81%	3.41%
Returns After Taxes on Distributions	11.69	-0.14	2.53
Returns After Taxes on Distributions and Sale of Fund Shares	8.27	0.68	2.75

About Your Fund’s Expenses

As a shareholder of the fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund’s gross income, directly reduce the investment return of the fund.

A fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period.

The accompanying table illustrates your fund’s costs in two ways:

• Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The ”Ending Account Value“ shown is derived from the fund‘s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period.

To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading ”Expenses Paid During Period.“

• Based on hypothetical 5% yearly return. This section is intended to help you compare your fund‘s costs with those of other mutual funds. It assumes that the fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case—because the return used is not the fund’s actual return—the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund’s costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

Note that the expenses shown in the table are meant to highlight and help you compare ongoing costs only and do not reflect transaction costs incurred by the fund for buying and selling securities. Further, the expenses do not include the transaction fees or the account service fee described in the prospectus. If such fees were applied to your account, your costs would be higher. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it carry a “sales load.” The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions.

You can find more information about the fund’s expenses, including annual expense ratios, in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to your fund’s current prospectus.

Six Months Ended October 31, 2010
	Beginning	Ending	Expenses
	Account Value	Account Value	Paid During
Windsor II Fund	4/30/2010	10/31/2010	Period
Based on Actual Fund Return
Investor Shares	$1,000.00	$977.13	$1.59
Admiral Shares	1,000.00	977.48	1.45
Based on Hypothetical 5% Yearly Return
Investor Shares	$1,000.00	$1,023.59	$1.63
Admiral Shares	1,000.00	1,023.74	1.48

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that period are 0.32% for Investor Shares and 0.29% for Admiral Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Glossary

30-Day SEC Yield. A fund’s 30-day SEC yield is derived using a formula specified by the U.S. Securities and Exchange Commission. Under the formula, data related to the fund’s security holdings in the previous 30 days are used to calculate the fund’s hypothetical net income for that period, which is then annualized and divided by the fund’s estimated average net assets over the calculation period. For the purposes of this calculation, a security’s income is based on its current market yield to maturity (in the case of bonds) or its projected dividend yield (for stocks). Because the SEC yield represents hypothetical annualized income, it will differ—at times significantly—from the fund’s actual experience. As a result, the fund’s income distributions may be higher or lower than implied by the SEC yield.

Beta. A measure of the magnitude of a fund’s past share-price fluctuations in relation to the ups and downs of a given market index. The index is assigned a beta of 1.00. Compared with a given index, a fund with a beta of 1.20 typically would have seen its share price rise or fall by 12% when the index rose or fell by 10%. For this report, beta is based on returns over the past 36 months for both the fund and the index. Note that a fund’s beta should be reviewed in conjunction with its R-squared (see definition). The lower the R-squared, the less correlation there is between the fund and the index, and the less reliable beta is as an indicator of volatility.

Dividend Yield. Dividend income earned by stocks, expressed as a percentage of the aggregate market value (or of net asset value, for a fund). The yield is determined by dividing the amount of the annual dividends by the aggregate value (or net asset value) at the end of the period. For a fund, the dividend yield is based solely on stock holdings and does not include any income produced by other investments.

Earnings Growth Rate. The average annual rate of growth in earnings over the past five years for the stocks now in a fund.

Equity Exposure. A measure that reflects a fund’s investments in stocks and stock futures. Any holdings in short-term reserves are excluded.

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

Foreign Holdings. The percentage of a fund represented by stocks or depositary receipts of companies based outside the United States.

Inception Date. The date on which the assets of a fund (or one of its share classes) are first invested in accordance with the fund’s investment objective. For funds with a subscription period, the inception date is the day after that period ends. Investment performance is measured from the inception date.

Median Market Cap. An indicator of the size of companies in which a fund invests; the midpoint of market capitalization (market price x shares outstanding) of a fund’s stocks, weighted by the proportion of the fund’s assets invested in each stock. Stocks representing half of the fund’s assets have market capitalizations above the median, and the rest are below it.

Price/Book Ratio. The share price of a stock divided by its net worth, or book value, per share. For a fund, the weighted average price/book ratio of the stocks it holds.

32

Price/Earnings Ratio. The ratio of a stock’s current price to its per-share earnings over the past year. For a fund, the weighted average P/E of the stocks it holds. P/E is an indicator of market expectations about corporate prospects; the higher the P/E, the greater the expectations for a company’s future growth.

R-Squared. A measure of how much of a fund’s past returns can be explained by the returns from the market in general, as measured by a given index. If a fund’s total returns were precisely synchronized with an index’s returns, its R-squared would be 1.00. If the fund’s returns bore no relationship to the index’s returns, its R-squared would be 0. For this report, R-squared is based on returns over the past 36 months for both the fund and the index.

Return on Equity. The annual average rate of return generated by a company during the past five years for each dollar of shareholder’s equity (net income divided by shareholder’s equity). For a fund, the weighted average return on equity for the companies whose stocks it holds.

Short-Term Reserves. The percentage of a fund invested in highly liquid, short-term securities that can be readily converted to cash.

Turnover Rate. An indication of the fund’s trading activity. Funds with high turnover rates incur higher transaction costs and may be more likely to distribute capital gains (which may be taxable to investors). The turnover rate excludes in-kind transactions, which have minimal impact on costs.

The People Who Govern Your Fund

The trustees of your mutual fund are there to see that the fund is operated and managed in your best interests since, as a shareholder, you are a part owner of the fund. Your fund’s trustees also serve on the board of directors of The Vanguard Group, Inc., which is owned by the Vanguard funds and provides services to them on an at-cost basis.

A majority of Vanguard’s board members are independent, meaning that they have no affiliation with Vanguard or the funds they oversee, apart from the sizable personal investments they have made as private individuals. The independent board members have distinguished backgrounds in business, academia, and public service. Each of the trustees and executive officers oversees 178 Vanguard funds.

The following table provides information for each trustee and executive officer of the fund. More information about the trustees is in the Statement of Additional Information, which can be obtained, without charge, by contacting Vanguard at 800-662-7447, or online at vanguard.com.

the vanguard FUNDS’

CODE OF Ethics

fOR

SENIOR executive and FINANCIAL OFFICERS

I.Introduction

 The Board of Trustees of each registered investment company that is managed, sponsored, and distributed by The Vanguard Group, Inc. (“VGI”) (each a “Vanguard Fund” and collectively the “Vanguard Funds”) has adopted this code of ethics (the “Code”) as required by Section 406 of the Sarbanes-Oxley Act.  The Code applies to the individuals in positions listed on Exhibit A (the “Covered Officers”).  All Covered Officers, along with employees of The Vanguard Group, Inc., are subject to separate and distinct obligations from this Code under a Code of Ethics adopted pursuant to Rule 17j-1 under the Investment Company Act of 1940 (“17j-1 Code of Ethics”), policies to prevent the misuse of non-public information, and other internal compliance guidelines and policies that may be in effect from time to time.

This Code is designed to promote:

·Honest and ethical conduct, including the ethical handling of conflicts of interest;

·Full, fair, accurate, timely, and understandable disclosure in reports and documents that a Vanguard Fund files with, or submits to, the U.S. Securities and Exchange Commission, or in other public communications made by the Vanguard Funds or VGI;

·Compliance with applicable laws, governmental rules, and regulations;

·Prompt internal reporting to those identified in the Code of violations of the Code; and

·Accountability for adherence to the Code.

II.Actual or Apparent Conflicts of Interest

A.  Covered Officers should conduct all activities in accordance with the following principles:

1.   Shareholders’ interests come first. In the course of fulfilling their duties and responsibilities to Vanguard Fund shareholders, Covered Officers must at all times place the interests of Vanguard Fund shareholders first.  In particular, Covered Officers must avoid serving their own personal interests ahead of the interests of Vanguard Fund shareholders.

2.   Conflicts of interest must be avoided.  Covered Officers must avoid any situation involving an actual or potential conflict of interest or possible impropriety with respect to their duties and responsibilities to Vanguard Fund shareholders.

3.   Compromising situations must be avoided.  Covered Officers must not take advantage of their position of trust and responsibility.  Covered Officers must avoid any situation that might compromise or call into question their exercise of full independent judgment in the best interests of Vanguard Fund shareholders.

All activities of Covered Officers should be guided by and adhere to these fiduciary standards regardless of whether the activity is specifically described in this Code.

B.   Restricted Activities

1.   Prohibition on secondary employment.  Covered Officers are prohibited from accepting or serving in any form of secondary employment.  Secondary employment that does not create a potential conflict of interest may be approved by the General Counsel of VGI.

2.Prohibition on service as director or public official.  Unless approved by the General Counsel of VGI, Covered Officers are prohibited from serving on the board of directors of any publicly traded company or in an official capacity for any federal, state, or local government (or governmental agency or instrumentality).

3.Prohibition on misuse of Vanguard time or property.  Covered Officers are prohibited from making use of time, equipment, services, personnel or property of any Vanguard entity for any purposes other than the performance of their duties and responsibilities in connection with the Vanguard Funds or other Vanguard-related entities.

III.Disclosure and Compliance

A.   Each Covered Officer should be familiar with the disclosure requirements generally applicable to the Vanguard Funds.

B.   Each Covered Officer should not knowingly misrepresent, or cause others to misrepresent, facts about the Vanguard Funds to others, including to the Vanguard Funds’ directors and auditors, or to government regulators and self-regulatory organizations.

C.   Each Covered Officer should, to the extent appropriate within the Covered Officer’s area of responsibility, consult with other officers and employees of VGI and advisers to a Vanguard Fund with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the fund files with, or submits to, the SEC and in other public communications made by a Vanguard Fund.

D.   It is the responsibility of each Covered Officer to promote compliance with the standards and restrictions imposed by applicable laws, rules, regulations, and the 17j-1 Code of Ethics.

IV.Reporting and Accountability

A.   Each Covered Officer must:

1.Upon adoption or amendment of the Code (or thereafter as applicable, upon becoming a Covered Officer), affirm in writing that he or she has received, read, and understands the Code;

2.Affirm at least annually in writing that he or she has complied with the requirements of the Code;

3.Not retaliate against any other Covered Officer or any employee of VGI for reports of potential violations of the Code that are made in good faith; and

4.Notify the General Counsel of VGI promptly if the Covered Officer knows of any violations of this Code.

B.   The Vanguard Funds will use the following procedures in investigating and enforcing this Code:

1.The General Counsel of VGI is responsible for applying this Code to specific situations and has the authority to interpret this Code in any particular situation.  The General Counsel will report on an as-needed basis to the Board of Trustees regarding activities subject to the Code. 

2.The General Counsel will take all appropriate action to investigate any potential violations of the Code that are reported to him.

3.If, after investigation, the General Counsel believes that no material violation of the Code has occurred, the General Counsel is not required to take any further action.

4.Any matter that the General Counsel believes is a material violation of the Code will be reported to the Board of Trustees of the Vanguard Funds.

5.If the Board of Trustees of the Vanguard Funds concurs that a material violation of the Code has occurred, the Board will consider appropriate action.  Appropriate action may include reassignment, suspension, or dismissal of the applicable Covered Officer(s), or any other sanctions the Board deems appropriate.  Appropriate action may also include review of, and appropriate modifications to, applicable policies and procedures.

6.Any changes to or waiver of this Code will, to the extent required, be disclosed as provided by SEC rules.

V.Other Policies and Procedures

This Code shall be the sole code of conduct adopted by the Vanguard Funds for purposes of Section 406 of the Sarbanes-Oxley Act and the rules and forms applicable to registered investment companies thereunder. Insofar as other policies or procedures of the Vanguard Funds, VGI, or other service providers govern or purport to govern the behavior or activities of the Covered Officers, they are superseded by this Code to the extent that they overlap or conflict with the provisions of this Code.

VGI’s and the Vanguard Funds’ 17j-1 Code of Ethics, policies to prevent the misuse of non-public information, and other internal compliance guidelines and policies that may be in effect from time to time are separate requirements applying to the Covered Officers and others, and are not part of this Code.

VI.        Amendments

            This Code may not be materially amended except by the approval of a majority vote of the independent trustees of the Vanguard Funds’ Board of Trustees.  Non-material, technical, and administrative revisions of the Code do not have to be approved by the Board of Trustees.   Amendments must be in writing and communicated promptly to the Covered Officers, who shall affirm receipt of the amended Code in accordance with Section IV. A. 1. 

VII.       Confidentiality

            All reports and records prepared or maintained pursuant to this Code shall be considered confidential and shall be maintained and protected accordingly.  Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone other than the Vanguard Funds’ Board of Trustees and VGI’s General Counsel.
