Item 7.01.     Regulation FD Disclosure

On July 17, 2006, Microsoft Corporation (“the Company”) issued a press release announcing that effective the first quarter of fiscal year 2007, it will report its businesses under five operating segments, reflecting completion of the previously announced changes in the Company’s organizational structure, and how the Company will manage its business beginning in fiscal year 2007. Each of the five segments will be organized under one of the three operating divisions announced earlier in fiscal year 2006:

• Microsoft Platforms and Services Division

• Microsoft Business Division

• Microsoft Entertainment and Devices Division

We are filing this Current Report on Form 8-K to provide the press release and certain other information to help investors better understand these changes.

The five operating segments are described below. The first three of these will compose the Microsoft Platforms and Services Division.

Client will include the former Client segment.

Server and Tools will include the former Server and Tools segment, excluding the Exchange Server business and certain client access licenses (CALs) related to products residing in the Microsoft Business Division.

Online Services Group will include the former MSN segment and Windows Live.

Microsoft Business Division will include the former Information Worker and Microsoft Business Solutions segments, as well as the Exchange Server business and certain CALs, formerly reported in the Server and Tools segment.

Microsoft Entertainment and Devices Division will include the former Home and Entertainment and Mobile and Embedded Devices segments.

To assist readers of the Company’s financial statements in analyzing these reporting changes and making comparisons of the Company’s financial information, we are voluntarily furnishing a summary of historical financial information previously disclosed in the Management’s Discussion and Analysis Section of our periodic reports, revised to reflect the new operating segment structure, which is attached hereto as Exhibit 99.1. This exhibit includes Segment Product Revenue/Operating Income (Loss), as previously reported and preliminary Segment Product Revenue/Operating Income (Loss) tables for the four quarters and fiscal year of fiscal 2005, and the first three quarters of fiscal year 2006, based on the new operating segment structure. The preliminary information in Exhibit 99.1 represents management’s calculations as of the date of this filing, and may change as final organizational changes may continue to take place in early fiscal year 2007.

In our annual report on Form 10-K for fiscal year 2006, the Company will report segment information using the seven operating segments that were in place for that period. The Company expects to include in its fiscal year 2006 Form 10-K a final analysis of both fiscal years 2005 and 2006 on a quarterly basis based on the new operating segment structure.

Microsoft Announces Changes to Financial Reporting Structure

Financial reporting change further aligns Microsoft along divisional structure

REDMOND, Wash. — July 17, 2006 — Microsoft Corporation today announced upcoming changes in its financial reporting structure reflecting completion of previously announced organizational changes. Beginning in fiscal year 2007, the company will report its financial performance based on five operating segments: Client, Server and Tools, Online Services Group, Microsoft Business Division, and Microsoft Entertainment and Devices Division.

Today’s news further aligns the company around three operating divisions – Microsoft Platforms and Services Division, Microsoft Business Division, and Microsoft Entertainment and Devices Division – previously created to achieve greater agility in managing future growth and execute on Microsoft’s software-based services strategy.

The Microsoft Platforms and Services Division includes the operating segments of Client, Server and Tools, and the Online Services Group. The Online Services Group includes MSN^® as well as Windows Live™. The company will continue to report results for each of these three segments, which is consistent with the way they are managed and reported within Microsoft.

The Microsoft Business Division includes the Information Worker and Microsoft Business Solutions businesses. These businesses have been merged and the financial results for these two businesses will be presented as one operating segment.

The Microsoft Entertainment and Devices Division includes the Home and Entertainment and Mobile and Embedded Devices businesses. These businesses have been merged and the financial results for these two businesses will be presented as one operating segment.

The company also previously announced the formation of the Unified Communications Group within the Microsoft Business Division, which includes the Exchange Server business. Financial results in fiscal year 2007 for the Exchange Server business, as well as certain client access licenses related to products residing in the Microsoft Business Division, will be included as part of the results in the Microsoft Business Division segment. Previously, the financial results for these products and licenses had been included in the Server and Tools segment.

The company will announce financial results for its fiscal fourth quarter on July 20, 2006 for the seven business segments under which the company operated in fiscal year 2006, and will provide fiscal year 2007 guidance under the new operating segment structure.

Financial Information

Financial segment information for the four quarters and the year for fiscal year 2005 and the first three quarters of fiscal year 2006, as if reported under the new operating segment structure, will be available in our 8-K filing on the company’s Web site at www.microsoft.com/MSFT.

Webcast Details

To assist investors in understanding the financial statement impacts of these changes and to answer questions regarding this announcement, Microsoft will hold an audio webcast

at 2:30 p.m. PDT (5:30 p.m. EDT) today with Chris Liddell, chief financial officer, and Frank Brod, corporate vice president and chief accounting officer. Earnings will be announced after market close on July 20, 2006 and discussion of fiscal fourth quarter results and fiscal year 2007 guidance will be deferred until that time.

The session may be accessed at http://www.microsoft.com/msft. The webcast will be available for replay through the close of business on July 17, 2007.
