                                  THE COMPANY

  Microsoft Corporation was founded as a partnership in 1975 and incorporated
in 1981. Microsoft develops, manufactures, licenses, sells, and supports a wide
range of software products, including:

  .  operating system software (for example, Microsoft Windows 98, Windows
     2000, and Windows CE) designed for personal computers, servers, handheld
     personal computers and other information devices;

  .  server applications software (for example, Microsoft Exchange Server and
     Microsoft SQL Server) designed for client/server environments;

  .  business and consumer applications software (for example, Microsoft
     Word; Microsoft Excel and Microsoft Outlook);

  .  software development tools; and

  .  Internet and intranet software and technologies.

  Microsoft's efforts also include:

  .  development of entertainment and information software programs;

  .  development of the MSN(TM) network of Internet products and services;

  .  alliances with companies involved with the creation and delivery of
     digital information;

  .  sales of personal computer devices such as the Microsoft Mouse and the
     Microsoft Natural Keyboard;

  .  publication of software-related books; and

  .  research and development of advanced technologies for future software
     products.

  Microsoft's business strategy is to develop a broad line of software products
for business and personal use, and to distribute these products through diverse
channels, including distributors, resellers, system integrators, retail stores,
and preinstalled on new computer hardware.

  Microsoft is organized as a Washington corporation with its principal
executive offices located at One Microsoft Way, Redmond, Washington 98052-6399.

                                 RISK FACTORS

  An investment in our common stock involves a high degree of risk. You should
consider the following factors carefully before deciding to purchase shares of
our common stock. Additional risks not presently known to us or that we
currently deem immaterial may also impair our business operations.

If we fail to develop or improve our existing products to meet or adapt to the
changing needs and standards of our industry in the face of intense
competition, sales of our products will decline and our business will suffer.

  We compete in the personal computer, or PC, software market, providing
software for personal and business computing. Rapid change, uncertainty due to
new and emerging technologies, and fierce competition characterize the PC
software industry. Our future growth may depend upon our ability to enhance
existing products, develop and introduce new products, satisfy customer
requirements and achieve market acceptance. This process is challenging since
the pace of change continues to accelerate, including "open source" software,
new computing devices, new microprocessor architectures, the Internet, and
Web-based computing models. If we do not successfully identify new product
opportunities and develop and bring new products to market in a timely and
cost-efficient manner, our business growth will suffer and demand for our
products will decrease.

  If we do not keep pace with products of our competitors and satisfy the
changing requirements of our customers, we may not achieve market acceptance
and we may be unable to attract new customers. We may also lose existing
customers, to whom we seek to sell additional software products. Further, the
PC software industry is inherently complex and we cannot accurately estimate
the life cycles of our products. New products and product enhancements can
require long development and testing periods, which require us to hire and
retain increasingly scarce, technically competent personnel. Significant
delays in new product releases or significant problems in creating new
products could damage our business.

  In our efforts to maintain and increase our market share, we continue to
expand our efforts to provide and support mission-critical systems to large
enterprises. In addition, we are developing a new generation of products and
key services for our customers that will use the Internet, rather than the
desktop, as the infrastructure. These products will combine Internet-hosted
platform services with the power of Windows-based PCs, servers and non-PC
devices. We cannot assure you that future revenues from these initiatives will
duplicate our historical revenue growth rates.

  The competition in the PC software industry is intense and may have multiple
effects. For example, competing companies and systems may gain market share,
which could have the effect of directly or indirectly reducing our existing
market share. In addition, competitors, working with new technology, may
arrive at a technology that creates a new market altogether and renders our
product offerings obsolete. We expect that the overall number of competitors
providing niche products that compete with ours will increase due to the
market's attractive growth. While we work closely with computer manufacturers
and developers, other companies promote their platforms and technologies
against our products and existing industry standards. These operating systems,
platforms, and products may gain popularity with customers, computer
manufacturers, and developers, reducing our future revenues. For example, we
are engaged in intense competition with Linus and Unix operating systems
companies for many business installations. This increased level of competition
may result in price reductions, lower-than-expected gross margins or our
inability to maintain our market share, any of which may result in a loss of
revenues and cause our business to suffer.

If the use of PCs for personal and business use does not continue to grow, we
will experience reduced product sales and lower revenue growth.

  Our revenue growth relies upon continued growth in the use of PCs for
personal and business use and the continued acceptance of the Windows
operating system and our applications software. Inexpensive PCs and specialty
devices create less demand for our software than traditional PCs because fewer
software products are

                                       4




typically included in the product by the manufacturer, users typically buy
fewer add-on software products, and prices for software have to be kept
relatively low to match the low cost of the devices. New PCs sold to users who
are replacing older PCs also generates less revenue for us because the buyers
may load previously purchased software onto their new machines, rather than
purchasing new software from us. As the percentage of households and
businesses with computers increases, these replacement sales will become a
larger part of total PC sales.

Prices of our products could decrease, which would reduce our net income.

  The competitive factors described above may require us to lower product
prices to meet competition. Since our cost of revenue is already very low,
price reductions would reduce our net income.

Developing and localizing software is expensive, and the investment in product
development often involves a long payback cycle.

  Our continued success depends in part on our continued ability to create
faster and better software products than our competitors. We plan to continue
significant investments in software research and development. We are also
making significant investments in online products and services such as MSN,
CarPoint, and HomeAdvisor, where we have the opportunity to establish
leadership in new businesses. We anticipate these investments in research and
development will increase over historical spending levels without
corresponding growth in revenues in the near future. We cannot assure you that
significant revenue from these product opportunities will be achieved for a
number of years, if at all.

Our international operations subject us to risks associated with rapid and
unexpected legal, political, economic, social, regulatory and other changes
outside of the U.S. that are not in our control.

  Much of our operations are conducted outside of the United States, and a
large percentage of sales, costs of manufacturing, and marketing is transacted
in local currencies. This exposes us to risks associated with converting
foreign currency into U.S. dollars. As a global concern, we face exposure to
adverse movements in foreign currency exchange rates. These exposures may have
an impact on our financial results. Further, future international and domestic
product prices may decrease from historical levels, depending on competitive
market and cost factors. European and Asian software prices vary by country
and are generally higher than in the U.S. to cover localization costs and
higher costs of distribution. Increased global license agreements, European
monetary unification, or other factors could erode such price uplifts in the
future. Any of these factors could result in a loss of revenues and slower
revenue growth.

  Negative changes in the following factors, among others, could also have an
impact on our business and results of operations:

  . unexpected changes in regulatory requirements for software;

  . social, political, labor or economic conditions in a specific country or
    region;

  . difficulties in staffing and managing foreign operations;

  . potential adverse tax consequences; and

  . trade protection laws, policies and measures and other regulatory
    requirements affecting trade and investment.

Our intellectual property rights may be difficult to protect.

  We diligently defend our intellectual property rights, but unlicensed
copying of software represents a loss of revenue. While this adversely affects
U.S. revenue, revenue loss is even more significant outside of the U.S.,
particularly in countries where laws are less protective of intellectual
property rights. Throughout the world, we actively educate consumers on the
benefits of licensing genuine products and educate lawmakers on the advantages
of a business climate where intellectual property rights are protected.
However, continued efforts may not affect revenue positively.

                                       5




We cannot predict the outcome or impact of recent antitrust claims by the U.S.
and several states, as well as a number of private antitrust litigation
claims.

  We are a party to numerous antitrust claims filed by the Antitrust Division
of the U.S. Department of Justice and a group of several state attorneys
general alleging violations of the Sherman Act. The Findings of Fact and
Conclusions of Law entered after the consolidated trial on the matters stated
that we had violated sections of the Sherman Act. A final Order was entered on
June 7, 2000 ordering, among other things, the breakup of Microsoft into two
companies: one which would conduct a business based on our operating systems
and another which would develop, market and sell our application products and
pursue all of our other activities. In addition the Order, if not stayed or
modified, would impose severe business conduct restrictions. We filed an
appeal on the final judgment and a motion to stay or suspend the conduct
restriction pending appeal on June 13, 2000 and intend to vigorously pursue
such actions. Although we expect to obtain relief from some or all of the
provisions in the Order we can not predict when or to what extent such relief
will be obtained. The failure to obtain sufficient relief through a stay
and/or the appeal, and the time it takes to resolve this dispute, could have a
material adverse effect on the value of Microsoft's common stock and/or the
stock of the two resulting companies if the divestiture is finally approved.
For more information concerning this litigation, particularly the current
status of the litigation which is changing very rapidly, you are encouraged to
review our other SEC filings, which are incorporated below under "Where You
Can Find More Information" and copies of orders, motions, briefs and other
court filings and press releases which are available at
www.microsoft.com/presspass/trial.

We may not be able to maintain our present revenue growth rate or operating
margins.

  Our revenue growth rate in 2000 may not approach the level attained in prior
years. Operating expenses are expected to increase from historical levels.
Because of the fixed nature of a significant portion of such expenses, coupled
with the possibility of slower revenue growth, operating margins may decrease
from historical levels.

                                USE OF PROCEEDS

  All net proceeds from the sale of the common shares covered by this
prospectus will go to the selling shareholders who offer and sell their
shares. We will not receive any proceeds from the sale of the common shares by
the selling shareholders.

                 SELLING SHAREHOLDERS AND PLAN OF DISTRIBUTION

  All of the common shares registered for sale under this prospectus will be
owned prior to the offer and sale of such shares by holders of put warrants
that have been issued by us to the "selling shareholders".

  All of the shares offered by the selling shareholders were acquired in the
settlement of put warrants that we issue from time to time. Generally, under
the terms of the agreements relating to the put warrants, if the selling
shareholder exercises the warrant and we elect to net-share settle the
warrant, we will issue shares of common stock of Microsoft to the selling
shareholder having a value equal to the product of the number of shares
subject to the warrant times the difference between the exercise price of the
warrant and the closing value of the Microsoft common shares on the expiration
date of the warrant (the "settlement value"). If the Microsoft common shares
received by the institutional investor are sold within 10 business days and
the net proceeds are less than the settlement value, we are obligated to pay
the difference in either cash or additional common shares which may also be
sold pursuant to this registration statement; conversely, if the net proceeds
are more than the settlement value, we will receive the difference in a cash
refund (the "make-whole" amount). The shares held by the selling shareholders
do not exceed one percent (1%) of Microsoft's outstanding capitalization. In
the past three years, Microsoft may have had commercial or investment banking
relationships with the selling shareholders; however we do not consider these
relationships to be material.

  We are registering the common shares covered by this prospectus for the
selling shareholders. As used in this prospectus, "selling shareholders"
includes the pledgees, donees, transferees or others who may later hold the
selling shareholders' interests. We will pay the costs and fees of registering
the common shares, but the selling shareholders will pay any brokerage
commissions, discounts or other expenses relating to the sale of the common
shares.

  The selling shareholders may sell the common shares in the over-the-counter
market or otherwise, at market prices prevailing at the time of sale, at
prices related to the prevailing market prices, or at negotiated prices. In
addition, the selling shareholders may sell some or all of their common shares
through:

  .  a block trade in which a broker-dealer or other person may resell a
     portion of the block, as principal or agent, in order to facilitate the
     transaction;

  .  purchases by a broker-dealer or other person, as principal, and resale
     by the broker-dealer for its account; or

  .  ordinary brokerage transactions and transactions in which a broker
     solicits purchasers.

  When selling the common shares, the selling shareholders may enter into
hedging transactions. For example, the selling shareholders may:

  .  enter into transactions involving short sales of the common shares by
     broker-dealers;

  .  sell common shares short themselves and deliver the shares registered
     hereby to settle such short sales or to close out stock loans incurred
     in connection with their short positions;

  .  enter into option or other types of transactions that require the
     selling shareholder to deliver common shares to a broker-dealer or other
     person, who will then resell or transfer the common shares under this
     prospectus; or

                                       7


  .  loan or pledge the common shares to a broker-dealer or other person, who
     may sell the loaned shares or, in the event of default, sell the pledged
     shares.

  The selling shareholders may negotiate and pay broker-dealers or other
persons commissions, discounts or concessions for their services. Broker-
dealers or other persons engaged by the selling shareholders may allow other
broker-dealers or other persons to participate in resales. However, the
selling shareholders and any broker-dealers or such other persons involved in
the sale or resale of the common shares may qualify as "underwriters" within
the meaning of the Section 2(a)(11) of the Securities Act of 1933 (the "1933
Act"). In addition, the broker-dealers' or their affiliates' commissions,
discounts or concession may qualify as underwriters' compensation under the
1933 Act. If the selling shareholders qualify as "underwriters," they will be
subject to the prospectus delivery requirements of Section 5(b)(2) of the 1933
Act.

  In addition to selling their common shares under this prospectus, the
selling shareholders may:

  .  agree to indemnify any broker-dealer or agent against certain
     liabilities related to the selling of the common shares, including
     liabilities arising under the 1933 Act;

  .  transfer their common shares in other ways not involving market makers
     or established trading markets, including directly by gift,
     distribution, or other transfer; or

  .  sell their common shares under Rule 144 of the 1933 Act rather than
     under this prospectus, if the transaction meets the requirements of Rule
     144.

  We have agreed to indemnify the selling shareholders against liabilities
arising in connection with this offering, including liabilities under the 1933
Act, or to contribute to payments that the selling shareholders may be
required to make in that respect.

  Additional information related to the selling shareholders and the plan of
distribution may be provided in one or more supplemental prospectuses.

                                 LEGAL MATTERS

  For purposes of this offering, Preston Gates & Ellis LLP, Seattle,
Washington, is giving its opinion on the validity of the common shares. As of
the date of this prospectus, attorneys in Preston Gates & Ellis LLP who have
worked on substantive matters for Microsoft own fewer than 1,000,000 common
shares.

Item 15. Indemnification of Directors and Officers.

  Article XII of the Restated Articles of Incorporation of Microsoft
authorizes Microsoft to indemnify any present or former director or officer to
the fullest extent not prohibited by the WBCA, public policy or other
applicable law. Chapter 23B.8.510 and .570 of the WBCA 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 Microsoft are entitled to indemnification by
each of the Selling Shareholders against any cause of action, loss, claim,
damage, or liability to the extent it arises out of or is based upon the
failure of any 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 Microsoft by such Selling
Shareholder or such underwriter.

  In addition, Microsoft maintains directors' and officers' liability
insurance under which Microsoft's directors and officers are insured against
loss (as defined in the policy) as a result of claims brought against them for
their wrongful acts in such capacities.

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 prospectus required by section 10(a)(3) of the 1933
  Act;

    (ii) 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. Notwithstanding the foregoing, any increase or
  decrease in volume of securities offered (if the total dollar value of
  securities

                                     II-1


  offered would not exceed that which was registered) and any deviation from
  the low or high end of the estimated maximum offering range may be
  reflected in the form of prospectus filed with the Commission pursuant to
  Rule 424(b) if, in the aggregate, the changes in volume and price represent
  no more than a 20% change in the maximum aggregate offering price set forth
  in the "Calculation of Registration Fee" table in the effective
  registration statement;

    (iii) 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)(i) and (1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by Microsoft 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 1933 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.

  (4) For purposes of determining any liability under the 1933 Act, each
filing of the registrant's annual report pursuant to Section 13(a) or Section
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 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.

  (5) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 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 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 Act
and will be governed by the final adjudication of such issue.

requirements for filing on Form S-3 and has duly caused this amendment no. 1
to its registration statement to be signed on its behalf by the undersigned,
thereunto duly authorized, in the City of Redmond, State of Washington on June
19, 2000.
