Childhood friends Bill Gates and Paul Allen sought to make a business using their skills in computer programming. In 1972, they founded Traf-O-Data, which sold a rudimentary computer to track and analyze automobile traffic data.

The January 1975 issue of Popular Electronics featured Micro Instrumentation and Telemetry Systems's (MITS) Altair 8800 microcomputer, which inspired Allen to suggest that they could program a BASIC interpreter for the device. Gates called MITS and claimed that he had a working interpreter, and MITS requested a demonstration. Allen worked on a simulator for the Altair while Gates developed the interpreter, and it worked flawlessly when they demonstrated it to MITS in March 1975 in Albuquerque, New Mexico. MITS agreed to distribute it, marketing it as Altair BASIC. Gates and Allen established Microsoft on April 4, 1975, with Gates as CEO, and Allen suggested the name "Micro-Soft", short for micro-computer software. In August 1977, the company formed an agreement with ASCII Magazine in Japan, resulting in its first international office of ASCII Microsoft. Microsoft moved its headquarters to Bellevue, Washington, in January 1979.

Microsoft entered the operating system (OS) business in 1980 with its own version of Unix, licensed from AT&T Corporation a year before, called Xenix, but it was MS-DOS that solidified the company's dominance. IBM awarded a contract to Microsoft in November 1980 to provide a version of the CP/M OS to be used in the IBM Personal Computer (IBM PC). For this deal, Microsoft purchased a CP/M clone called 86-DOS from Seattle Computer Products which it branded as MS-DOS, although IBM rebranded it to IBM PC DOS. Microsoft retained ownership of MS-DOS following the release of the IBM PC in August 1981. IBM had copyrighted the IBM PC BIOS, so other companies had to reverse engineer it for non-IBM hardware to run as IBM PC compatibles, but no such restriction applied to the operating systems. The company expanded into new markets with the release of the Microsoft Mouse in 1983, as well as with a publishing division named Microsoft Press. Paul Allen resigned from Microsoft in 1983 after developing Hodgkin's lymphoma.

Microsoft released Windows 1.0 on November 20, 1985, as a graphical extension for MS-DOS, despite having begun jointly developing OS/2 with IBM that August. …

Microsoft is ranked No. 14 in the 2022 Fortune 500 rankings of the largest United States corporations by total revenue; and it was the world's largest software maker by revenue in 2022 according to Forbes Global 2000. In 2018, Microsoft became the most valuable publicly traded company in the world, a position it has repeatedly traded with Apple in the years since. In April 2019, Microsoft became the third U.S. public company to be valued at over $1 trillion. As of 2024, Microsoft has the third-highest global brand valuation. Microsoft is one of only two U.S.-based companies that have a prime credit rating of AAA. It is a Big Tech company.

The company is run by a board of directors made up of mostly company outsiders, as is customary for publicly traded companies. Members of the board of directors as of December 2023 are Satya Nadella, Reid Hoffman, Hugh Johnston, Teri List, Sandi Peterson, Penny Pritzker, Carlos Rodriguez, Charles Scharf, John W. Stanton, John W. Thompson, Emma Walmsley and Padmasree Warrior.

Board members are elected every year at the annual shareholders' meeting using a majority vote system. There are four committees within the board that oversee more specific matters. These committees include the Audit Committee, which handles accounting issues with the company including auditing and reporting; the Compensation Committee, which approves compensation for the CEO and other employees of the company; the Governance and Nominating Committee, which handles various corporate matters including the nomination of the board; and the Regulatory and Public Policy Committee, which includes legal/antitrust matters, along with privacy, trade, digital safety, artificial intelligence, and environmental sustainability.

On March 13, 2020, Gates announced that he is leaving the board of directors of Microsoft and Berkshire Hathaway to focus more on his philanthropic efforts. According to Aaron Tilley of The Wall Street Journal this is "marking the biggest boardroom departure in the tech industry since the death of longtime rival and Apple Inc. …

[T]he Microsoft method. Understand the market, and the customers, and then go pedal to the metal, with release after release focused on what the customers need, incorporating their feedback. That puts the competition into reaction mode. And of course it helps if they also make a strategic error because they are under so much pressure.

Technical references for developers and articles for various Microsoft magazines such as Microsoft Systems Journal (MSJ) are available through the Microsoft Developer Network (MSDN). MSDN also offers subscriptions for companies and individuals, and the more expensive subscriptions usually offer access to pre-release beta versions of Microsoft software. In April 2004, Microsoft launched a community site for developers and users, titled Channel 9, that provides a wiki and an Internet forum. Another community site that provides daily videocasts and other services, On10.net, launched on March 3, 2006. Free technical support is traditionally provided through online Usenet newsgroups, and CompuServe in the past, monitored by Microsoft employees; there can be several newsgroups for a single product. Helpful people can be elected by peers or Microsoft employees for Microsoft Most Valuable Professional (MVP) status, which entitles them to a sort of special social status and possibilities for awards and other benefits.

Noted for its internal lexicon, the expression "eating your own dog food" is used to describe the policy of using pre-release and beta versions of products inside Microsoft to test them in "real-world" situations. This is usually shortened to just "dog food" and is used as a noun, verb, and adjective. Another bit of jargon, FYIFV or FYIV ("Fuck You, I'm [Fully] Vested"), is used by an employee to indicate they are financially independent and can avoid work anytime they wish.

Microsoft is an outspoken opponent of the cap on H-1B visas, which allows companies in the U.S. to employ certain foreign workers. Bill Gates claims the cap on H1B visas makes it difficult to hire employees for the company, stating "I'd certainly get rid of the H1B cap" in 2005. Critics of H1B visas argue that relaxing the limits would result in increased unemployment for U.S. …
