What is the main purpose of this 8-K filing?

The primary purpose of this 8-K filing is for Microsoft Corporation to test and demonstrate the use of XBRL (Extensible Business Reporting Language) for financial reporting. It provides XBRL-formatted data related to their financial information from the Q3 2005 10-Q.

Should I use the financial information in this filing for investment decisions?

No, absolutely not. The filing explicitly states that the XBRL-formatted financial information is unaudited and is for testing purposes only. Investors should continue to rely on the official, officially filed versions of Microsoft's financial statements.

What does it mean that the XBRL data is not 'filed'?

This means that under SEC rules (specifically Rule 402 of Regulation S-T), the XBRL data submitted in this 8-K is not considered officially filed with the SEC. Consequently, it is not subject to the liability provisions of Section 18 of the Securities Exchange Act of 1934, which typically applies to misstatements in filed documents.

Which parts of the Q3 2005 10-Q are included in the XBRL exhibit?

The XBRL exhibit (Exhibit 100) contains information from Part I (Items 1(a)-(e) and Items 2-4) and Part II (Items 1 and 2) of Microsoft's Form 10-Q for the quarter ended September 30, 2005.
