                                   PROSPECTUS

                             MICROSOFT CORPORATION
                         57,120  Shares of Common Stock
                         Par Value of $.00005 Per Share     

                               ----------------

         This Prospectus relates to up to 57,120 shares of common stock (the
"Shares") of Microsoft Corporation (the "Company") which may be offered from
time to time by the selling shareholders named herein (the "Selling
Shareholders").  The Company will not receive any of the proceeds from the sale
of the Shares.  The Company will bear the costs relating to the registration of
the Shares estimated to be approximately $6,000.

         The Shares are registered as a result of a merger (the "Merger") of
Microsoft Corporation, a Washington corporation ("Microsoft") and One Tree
Software, Inc., a North Carolina corporation ("One Tree").  In an agreement
related to the Merger, each Selling Shareholder entered into an escrow
agreement and an investment agreement with Microsoft (the collectively
"Agreements").  The Agreements limit the amount of shares the Selling
Shareholder may sell during the first two years after the Merger is
consummated.

        The Company has been advised by each Selling Shareholder that, subject
to the terms of the Agreements, he expects to offer his shares through brokers
and dealers to be selected by him from time to time.  The Shares may be offered
for sale through the Nasdaq Stock Market, in the over-the-counter market, in
one or more private transactions, or a combination of such methods of sale, at
prices and on terms then prevailing, at prices related to such prices, or at
negotiated prices.  Subject to the terms of the Agreements, each Selling
Shareholder may pledge all or a portion of the Shares owned by him or her as
collateral in loan transactions.  Upon default by such a Selling Shareholder
the pledgee in such loan transaction would have the same rights of sale as the
Selling Shareholder under this Prospectus.  Subject to the terms of the
Agreements, each Selling Shareholder may also transfer Shares owned by him by
gift and upon any such transfer the donee would have the same rights of sale as
such Selling Shareholder under this Prospectus.  Each Selling Shareholder and
any brokers and dealers through whom sales of the Shares are made may be deemed
to be "underwriters" within the meaning of the Securities Act of 1933, as
amended, and the commissions or discounts and other compensation paid to such
persons may be regarded as underwriters' compensation.

   
         The Shares are traded on the Nasdaq Stock Market.  The average of the
high and low prices of the Shares as reported on the Nasdaq Stock Market on
February 15, 1995 was $60.50 per share.
    

 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
            EXCHANGE COMMISSION NOR HAS THE COMMISSION PASSED UPON
    THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS.  ANY REPRESENTATION TO THE
                        CONTRARY IS A CRIMINAL OFFENSE.

                               ----------------

   
               The date of this Prospectus is February 17, 1995.
    

All of the securities to be registered hereby are to be offered for the account
                             of security holders.

              DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION
                         FOR SECURITIES ACT LIABILITIES

         Article  XII of the Company's Restated Articles of Incorporation
authorizes the Company to indemnify any present or former director, officer,
employee, or agent of the Company, or a person serving in a similar post in
another organization at the request of the Company, against expenses,
judgments, fines, and amounts paid in settlement incurred by him in connection
with any threatened, pending, or completed action, suit, or proceeding, whether
civil, criminal, administrative, or investigative, to the fullest extent not
prohibited by the Washington Business Corporation Act, public policy or other
applicable law.  Chapter 23B.08.510 and .570 of the Washington Business
Corporation Act authorizes a corporation to indemnify its directors, officers,
employees, or agents in terms sufficiently broad to permit such indemnification
under certain circumstances for liabilities (including provisions permitting
advances for expenses incurred) arising under the 1933 Act.

         Insofar as indemnification for liabilities arising under the 1933 Act
may be permitted to directors, officers, or persons controlling the registrant
pursuant to the foregoing provisions, the Registrant has been informed that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the 1933 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 1933 Act and will be governed by the
final adjudication of such issue.

                                                                          =========
                                                                  

Item 15.         Indemnification of Directors and Officers.

         Article  XII of the Restated Articles of Incorporation of the Company
authorizes the Company to indemnify any present or former director or officer
to the fullest extent not prohibited by the Washington Business Corporation
Act, public policy or other applicable law.  Chapter 23B.8.510 and .570 of the
Washington Business Corporation Act authorizes a corporation to indemnify its
directors, officers, employees, or agents in terms sufficiently broad to permit
such indemnification under certain circumstances for liabilities (including
provisions permitting advances for expenses incurred) arising under the 1933
Act.

         The directors and officers of the Company are entitled to
indemnification by the Selling Shareholder against any cause of action, loss,
claim, damage, or liability to the extent it arises out of or is based upon the
failure of the Selling Shareholder (or his donees, legatees, or pledgees) and
each underwriter to comply with the Prospectus delivery requirements under the
federal securities laws or any applicable state securities laws or upon any
untrue statement or alleged untrue statement or omission or alleged omission
made in this Registration Statement and the Prospectus contained herein, as the
same shall be amended or supplemented, made in reliance upon or in conformity
with written information furnished to the Company by such Selling Shareholder
(or his donees, legatees, and pledgees) or such underwriter.

Item 16.         List of Exhibits.

         The Exhibits to this registration statement are listed in the Index to
Exhibits on page  II-4.

Item 17.         Undertakings.

         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:

                 (i)      To include any material information with respect to
         the plan of distribution not previously disclosed in the registration
         statement or any material change to such information in the
         registration statement;





                                      II-1

         (2)     That, for the purpose of determining any liability under the
Securities Act of 1933, 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.

         (4)     For purposes of determining any liability under the Securities
Act of 1933, each filing of the registrant's annual report pursuant to Section
13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by
reference in the 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.
