PART II

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3. Incorporation of Documents by Reference.

The following documents filed by Microsoft with the Securities and Exchange Commission (the “Commission”) are hereby incorporated by reference in this registration statement:

(a) Microsoft’s Annual Report on Form 10-K for the fiscal year ended June 30, 2025, filed on July 30, 2025, which contains Microsoft’s audited financial statements for the latest fiscal year for which such statements have been filed; and

(b) All other reports of Microsoft filed with the Commission, pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) since the end of the fiscal year covered by Microsoft’s Annual Report referred to in (a) above.

All documents filed by Microsoft pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act, after the date hereof (excluding any documents or portions of such documents that are furnished under Item 2.02 or Item 7.01 of a current report on Form 8-K and any exhibits included with such Items), and prior to the filing of a post-effective amendment that indicates that all the securities offered hereby have been sold or that deregisters the securities offered hereby then remaining unsold, shall also be deemed to be incorporated by reference into this registration statement and to be a part hereof from the date of filing of such documents.

Any statement contained in this registration statement or in a document incorporated or deemed to be incorporated by reference in this registration statement will be deemed to be modified or superseded to the extent that a statement contained herein or in any other subsequently filed document which also is or is deemed to be incorporated by reference in this registration statement modifies or supersedes that statement. Any statement so modified or superseded will not be deemed, except as so modified or superseded, to constitute a part of this registration statement.

Item 4. Description of Securities.

The securities being registered pursuant to the Microsoft Corporation Deferred Compensation Plan (the “Plan”) represent obligations (“Obligations”) of the Registrant to pay deferred compensation in the future in accordance with the terms of the Plan, which is filed as Exhibit 99.1 to this registration statement. Eligible employees of the Registrant are entitled to defer receipt of certain compensation into the Plan.

The Obligations are general unsecured obligations of the Registrant subject to the claims of its general creditors. The Plan is considered unfunded for tax purposes.

The amount of compensation to be deferred by each participating eligible employee (individually, a “Participant” and collectively, the “Participants”) is determined in accordance with the Plan based on elections by each Participant.

Under the Plan, amounts credited to a Participant’s account are credited with deemed investment returns equal to the experience of certain investment funds offered under the Plan and selected by the Participant. The Obligations are generally payable upon a date or dates selected by the Participant under the Plan, subject to exceptions for in-service withdrawals for an Unforeseeable Emergency (as defined in the Plan) or certain terminations of employment. The Obligations generally are payable in cash in the form of a lump-sum distribution or in installments, at the election of the Participant.

A Participant may designate one or more beneficiaries to receive any portion of the Obligations payable in the event of death. Participants or beneficiaries generally may not anticipate, alienate, sell, transfer, assign or otherwise dispose of any right or interest in the plan in which they are participating. The Registrant reserves the right to amend or terminate the Plan.

Item 5. Interests of Named Experts and Counsel.

None.

Item 6. Indemnification of Directors and Officers.

Sections 23B.08.510 and 23B.08.570 of the Washington Business Corporation Act (“WBCA”) authorize Washington corporations to indemnify their officers and directors under certain circumstances against expenses and liabilities incurred in legal proceedings involving them as a result of their service as an officer or director. Section 23B.08.560 of the WBCA authorizes a corporation by provision in its articles of incorporation to indemnify or agree to indemnify a director made a party to a proceeding, or obligate itself to advance or reimburse expenses incurred in a proceeding, without regard to the limitations imposed by Sections 23B.08.510 through .550 of the WBCA; provided, however, that no such indemnity shall be made for or on account of (a) acts or omissions of the director finally adjudged to be intentional misconduct or a knowing violation of law, (b) conduct of the director finally adjudged to be in violation of Section 23B.08.310 of the WBCA (relating to unlawful distributions) or (c) any transaction with respect to which it was finally adjudged that the director personally received a benefit in money, property, or services to which the director is not legally entitled.

Microsoft’s Amended and Restated Articles of Incorporation require indemnification of Microsoft’s officers and directors and advancement of expenses to the fullest extent not prohibited by applicable law. Microsoft’s Amended and Restated Articles of Incorporation provide for procedures for those seeking indemnification and/or advancement of expenses. In addition, as authorized by Section 23B.08.320 of the WBCA, Microsoft’s Amended and Restated Articles of Incorporation contain a provision eliminating the personal liability of directors to Microsoft or its shareholders for monetary damages for conduct as a director, except for (a) omissions involving intentional misconduct by the director or a knowing violation of law by the director, (b) conduct violating Section 23B.08.310 of the WBCA or (c) any transaction from which the director will personally receive a benefit in money, property or services to which the director is not legally entitled.

Microsoft has established an indemnification trust (“2025 Directors’ Trust”) to fund Microsoft’s obligations to indemnify and/or advance expenses to directors arising from their board service in the event Microsoft does not or is financially unable to provide the indemnification and/or advancement. As required by the 2025 Directors’ Trust agreement, Microsoft has funded a minimum balance of principal assets of no less than $50 million in the trust. Microsoft also has an indemnification trust (“2025 Officers’ Trust”) that funds Microsoft’s indemnification obligations to certain past and present officers arising from their activities as such. As required by the 2025 Officers’ Trust agreement, Microsoft has funded a minimum balance of principal assets of no less than $50 million in the trust. The 2025 Directors’ Trust and 2025 Officers’ Trust are successors to certain trusts originally established in 1993, and amended from time to time, to fund Microsoft’s indemnification obligations to directors and officers.

Item 7. Exemption from Registration Claimed.

Not applicable.

Item 9. Undertakings.

A. The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(a) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended (the “Securities Act”);

(b) To reflect in the prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement; and

(c) To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement; provided, however, that paragraphs (1)(a) and (1)(b) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this registration statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

B. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

C. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that, in the opinion of the Commission, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Exhibit 5.1

December 30, 2025

Microsoft Corporation

One Microsoft Way

Redmond, Washington 98052-6399

Ladies and Gentlemen:

We have acted as counsel for Microsoft Corporation, a Washington corporation (“Microsoft”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of Microsoft’s Registration Statement on Form S-8 (the “Registration Statement”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration of an aggregate of $1,200,000,000 in deferred compensation obligations that may be offered pursuant to the Microsoft Corporation Deferred Compensation Plan (the “Plan”).

As your legal counsel, we have reviewed the actions proposed to be taken by you in connection with the deferred compensation obligations that may be offered pursuant to the terms of the Plan.

In connection with this opinion, we have examined and relied upon originals or copies, certified or otherwise identified to our satisfaction, of (i) the Amended and Restated Articles of Incorporation of Microsoft Corporation, (ii) the Bylaws of Microsoft Corporation, (iii) the Registration Statement, (iv) the Plan, and (v) such corporate records, agreements, documents and other instruments, and such certificates or comparable documents of public officials and of officers and representatives of Microsoft, and have made such inquiries of such officers and representatives, as we have deemed relevant and necessary or appropriate as a basis for the opinion set forth below.

In our examination, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as facsimile, electronic, certified or photostatic copies, and the authenticity of the originals of such copies. In making our examination of documents executed or to be executed, we have assumed that the parties thereto, other than Microsoft, had or will have the power, corporate or other, to enter into and perform all obligations thereunder and have also assumed the due authorization by all requisite action, corporate or other, and the execution and delivery by such parties of such documents and the validity and binding effect thereof on such parties. As to any facts material to the opinions expressed herein that we did not independently establish or verify, we have relied upon statements and representations of officers and other representatives of Microsoft and others and of public officials.

December 30, 2025

Page 2

The opinion expressed herein is limited to the corporate laws of the State of Washington and the federal laws of the United States of America, and we express no opinion as to the effect on the matters covered by this letter of the laws of any other jurisdictions. For purposes of the opinion set forth below, we have assumed that the Plan has been established and is intended to be maintained as a “top hat” plan under the Employee Retirement Income Security Act of 1974, as amended, which is a plan that is unfunded and maintained by an employer primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees.

Based on the foregoing and subject to the limitations, qualifications and assumptions set forth herein, we are of the opinion that the deferred compensation obligations offered pursuant to the terms of the Plan will be valid and binding obligations of Microsoft, enforceable against Microsoft in accordance with their terms and the terms of the Plan, except that such enforceability (i) may be limited by bankruptcy, insolvency, reorganization or other similar laws effecting creditors’ rights generally, and (ii) subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). In addition, the manner in which any particular issue relating to the foregoing opinions would be treated in any actual court case would depend in part on facts and circumstances particular to the case and would also depend on how the court involved chose to exercise the wide discretionary authority generally available to it.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement. In giving such consent, we do not hereby admit that we are included in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder.

Very truly yours,

/s/ Orrick, Herrington & Sutcliffe LLP
