Exhibit 19.1

General Insider Trading Policy

1. PURPOSE

To prevent the misuse of material, nonpublic information about Microsoft or other publicly traded companies obtained by virtue of your position at Microsoft.

2. SUMMARY

This policy and Federal and State securities laws prohibit a person from trading in securities of a company when that person has material, nonpublic information relating to that company.

As an employee of Microsoft, you may have access to financial, business, or other information about Microsoft, or other companies, that is both material and not available to the public. If you are in possession of material, nonpublic information about any company, including Microsoft, the securities laws and Microsoft prohibit you from trading in (or gifting) the securities of that company, and you may not disclose the information to anyone else, except as specifically authorized in the performance of your job responsibilities.

This policy also applies to:

•immediate family members who live with you or use your address as their regular address (e.g., spouse, domestic partner, minor children, college students, parents, grandparents, grandchildren, siblings and in-laws);

•trusts, if you are: (1) a trustee who has or shares investment control of the trust securities and you or a member of your immediate family (whether or not they live with you) has an economic interest in the trust securities; (2) a beneficiary who has or shares investment control; or (3) a person who has the power to revoke the trust; and

•partnerships or other entities over which you have a controlling influence.

You are responsible for assuring that individuals or entities listed above comply with this policy.

3. REQUIREMENTS

A.Do Not Trade While in Possession of Material, Nonpublic Information

As an employee of Microsoft, you may have access to financial, business and other information about Microsoft or other companies. When you possess information about Microsoft that is both material and nonpublic, the securities laws and Microsoft prohibit you from buying or selling (or gifting) Microsoft securities.

1

Similarly, when you possess material, nonpublic information about any publicly traded company that you acquired through your role at Microsoft, including but not limited to a customer or partner of Microsoft or an economically-linked company such as a competitor of Microsoft, the securities laws and Microsoft prohibit you from buying or selling securities in that company.

•Information is 'material' if there is a substantial likelihood that a reasonable investor would consider it important in deciding whether to buy or sell that company's securities.

•Information is 'nonpublic' if it has not been broadly communicated to the marketplace in a manner making it generally available to the investing public. Rumors, even if true and widely reported in the media, do not constitute public disclosure unless publicly confirmed by the company to which it relates.

Common examples of material information may include:

•Financial results

•Internal projections that significantly differ from external expectations

•Significant proposed or pending acquisitions, dispositions, mergers or joint ventures

•Changes in key executives

•Significant plans, developments or problems related to important products and services

•Changes in the terms of a significant contract with a major customer or partner, or the acquisition or loss of such a contract

•Cybersecurity risks and incidents (including vulnerabilities and breaches)

•Significant litigation or regulatory actions

•Other notable transactions, events or developments outside the ordinary course of business

Material information can be good news or bad news, and can relate to any aspect of a company's business. Either way, the law prohibits making profits and avoiding losses by using material, nonpublic information. It makes no difference whether you receive the information during the course of your job responsibilities or overhear it in the hallway or lunchroom, or anywhere at or away from your normal workplace.

B.Do Not Disclose Material, Nonpublic Information to Others

Do not disclose material, nonpublic information about Microsoft, or another publicly traded company, to anyone else. This is considered illegal 'tipping' and you could be held criminally liable under federal law even if you yourself did not make a trade.

Do not recommend or suggest that anyone else trade the securities of any company, including Microsoft, even if you do not disclose the material, nonpublic information.

C.Limited Exceptions to These Restrictions

There are a few situations where transactions in securities are not prohibited even if you have material, nonpublic information.

•Purchases of Microsoft stock through an existing purchase election under the Employee Stock Purchase Plan (ESPP). However, you may sell your ESPP shares only at a time when you do not have material, nonpublic information.

2

•Acquiring Microsoft stock through the vesting of employee Stock Awards. You may sell your Stock Award shares only at a time when you do not have material, nonpublic information.

•Exercising options, if you pay the exercise price and withholding taxes in cash. Again, you may sell your shares only at a time when you do not have material, nonpublic information.

•Trades made pursuant to a predetermined, written Rule 10b5-1 Trading Plan. For information on Trading Plans and the specific policies and procedures associated with them, please visit the Rule 10b5-1 Trading plans page.

D.Restrictions on Microsoft Officers and Other Designated Employees

Microsoft has a policy requiring certain officers of the company (corporate vice presidents and above) and other designated employees to only transact in Microsoft securities during specific times throughout the year, commonly referred to as 'trading windows'. Those officers and employees will be notified if they are subject to the Restricted Trading Window Policy.
