Quick Answer
If you are diving into the history of modern computing, one of the most foundational questions to ask is: When was Microsoft established? The software giant was officially founded on April 4, 1975. Childhood friends Bill Gates and Paul Allen started the company in Albuquerque, New Mexico, with a shared, revolutionary vision: to put a computer on every desk and in every home.
The Spark: The Altair 8800
The story of Microsoft's founding begins slightly before its official incorporation, sparked by a magazine article. In January 1975, Popular Electronics featured the Altair 8800, one of the world’s first microcomputers. Paul Allen saw the magazine and immediately showed it to Bill Gates, who was then a student at Harvard University.
Realizing that this new hardware would need software to be truly useful, they boldly called Micro Instrumentation and Telemetry Systems (MITS), the creators of the Altair, and claimed they had developed a BASIC interpreter for the machine. In reality, they hadn't written a single line of code for it yet. Working frantically in Harvard's computer lab, they successfully developed the software in just eight weeks. The demonstration was a massive success, and MITS agreed to distribute their software. This vital victory led to the formal creation of Microsoft in April of that same year.
Why Albuquerque, New Mexico?
Many people associate Microsoft with the Pacific Northwest, but its first home was the American Southwest. Gates and Allen chose to establish Microsoft in Albuquerque, New Mexico, simply because that was where MITS was headquartered. Being physically close to their very first hardware partner was crucial for their early software development. They remained in New Mexico until 1979, when they finally relocated the company to Bellevue, Washington, closer to their childhood home of Seattle.

Key Steps That Secured Microsoft's Early Success
The transition from a small startup to a billion-dollar company was not accidental. Gates and Allen utilized several brilliant strategies that laid the groundwork for modern software economics:
Pioneering Software Licensing: Instead of selling their software outright, Microsoft licensed it. This meant they retained the copyright and could sell the same software to multiple hardware manufacturers, creating a massive, scalable revenue stream.
The IBM Partnership (1980): When IBM needed an operating system for its first personal computer, Microsoft secured the contract. They purchased an existing system (86-DOS), adapted it into MS-DOS, and crucially, retained the right to license it to other computer brands.
Embracing Open Hardware: By allowing MS-DOS (and later Windows) to run on "IBM-compatible" clone PCs, Microsoft ensured their software became the universal standard for personal computing globally.
Frequently Asked Questions (FAQs)
Who originally came up with the name Microsoft?
Paul Allen is credited with coming up with the original name. Initially, it was hyphenated as "Micro-Soft" to reflect the combination of microcomputers and software, but they dropped the hyphen in 1976 when they formally registered the trade name.
When did Microsoft release Windows?
While the company was established in 1975, the famous Windows operating system did not debut until November 20, 1985. Windows 1.0 was essentially a graphical user interface layered over their existing MS-DOS command-line system.
Did Bill Gates drop out of college to start Microsoft?
Yes. Bill Gates officially took a leave of absence from Harvard University in 1975 to focus entirely on building Microsoft in Albuquerque. He never returned to complete his undergraduate degree.
Conclusion
Whenever tech enthusiasts ask, "When was Microsoft established?", they are looking back at the exact moment the software industry was truly born. Before April 4, 1975, computer hardware was the only thing that mattered to investors. Bill Gates and Paul Allen fundamentally shifted the technology landscape by proving that the code running inside the machine was just as valuable—if not more so—than the machine itself. From a small office in New Mexico to a sprawling campus in Redmond, Washington, Microsoft's founding principles paved the way for the digital age we live in today.
