Ladies and Gentlemen:

I am Deputy General Counsel and Corporate Secretary of Microsoft Corporation, a Washington corporation (the “Company”). I have acted in such capacity in connection with the Registration Statement on Form S-3 (the “Registration Statement”) filed by the Company with the Securities and Exchange Commission under the Securities Act of 1933, as amended, relating to the issuance by the Company from time to time of senior unsecured debt securities (the “Securities”). The Securities will be issued under supplemental indentures (the “Supplemental Indentures”) between the Company and the trustee named therein (each, a “Trustee”), to the indenture, dated as of May 18, 2009 (the “Base Indenture” and, as amended and supplemented by the Supplemental Indentures, the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee.

I, or the attorneys under my supervision, have examined the Registration Statement and the Base Indenture. In addition, I, or the attorneys under my supervision, have examined, and relied as to matters of fact upon, originals, or duplicates or certified or conformed copies, of such records, agreements, documents and other instruments and such certificates or comparable documents of public officials and of officers and representatives of the Company and have made such other investigations as I have deemed relevant and necessary in connection with the opinion hereinafter set forth.

In rendering the opinion set forth below, I have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to me as originals, the conformity to original documents of all documents submitted to me as duplicates or certified or conformed copies and the authenticity of the originals of such latter documents. I also have assumed that the Indenture will be the valid and legally binding obligation of the applicable Trustees.

Based upon the foregoing, and subject to the qualifications, assumptions and limitations stated herein, I am of the opinion that the Securities have been duly authorized and, when executed and delivered in accordance with the Indenture, will be duly executed and delivered by the Company in accordance with the law of the State of Washington.

The opinion set forth above is subject to (i) the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally, (ii) general equitable principles (whether considered in a proceeding in equity or at law) and (iii) an implied covenant of good faith and fair dealing.

I do not express any opinion herein concerning any law other than the law of the State of Washington.

In rendering its opinion, Simpson Thacher & Bartlett LLP may rely upon this opinion as to matters of the law of the State of Washington addressed herein as if this opinion were addressed directly to them.

I hereby consent to the filing of this opinion letter as Exhibit 5.2 to the Registration Statement and to the use of my name under the caption “Validity of the Securities” in the prospectus included in the Registration Statement.
