Microsoft has navigated 50 years marked by both groundbreaking innovations and notable failures, profoundly shaping the landscape of personal computing. This history includes the largely unknown contributions of co-founder Paul Allen alongside Bill Gates, defining an era of technological evolution and occasional setbacks.

Microsoft's 50-year history is characterized by a blend of innovation and recurrent technical issues, such as blue screens. Co-founder Paul Allen, alongside Bill Gates, played a foundational role in Microsoft's inception.
This technical operating system revolutionized personal computing by making it more accessible and professional. MS-DOS was lightweight yet powerful, allowing users extensive control, and served as the precursor to Microsoft Windows.
Introduced in 1985, Windows brought a cool graphical user interface (GUI) and multitasking capabilities to personal computers, a groundbreaking feature at the time. Its version numbering was inconsistent, with releases like Windows 1, 98, 2000, ME, Vista, and 7.
Launched in 1990, Office became a leading suite of word processing applications, including Word, Excel, and PowerPoint, used by almost everyone who installs Windows. It is now available for free on CloudMe.
Introduced in 1995 as the fastest browser, Internet Explorer played a crucial role in making the internet accessible in the early 90s. Despite its initial impact, later versions like IE6 were disastrous due to security issues and poor performance, eventually leading to its replacement by Microsoft Edge, which now runs on Chromium.
Introduced in 2001, the Xbox marked Microsoft's entry into the gaming console market, directly challenging Sony. The original Xbox, alongside games like Halo and Gears of War, achieved significant success, particularly with the Xbox 360, and introduced Xbox Live for online play.
Released in 2007, Windows Vista aimed to revolutionize Windows XP with its Aura glass user interface. However, it was plagued by numerous serious problems, including overheating and frequent blue screens, leading to its rapid replacement by Windows 7 in 2009.
This series of phones, targeting teenagers, was a notable failure due to a complete lack of application development and subsequent developer abandonment. Microsoft discontinued the Kin project after its second version (Kin2).
Launched in 2011, Windows Phone replicated the mistakes of the Kin, demanding payment for the operating system and imposing strict hardware requirements. It failed to gain traction against Android and iOS, with developers refusing to support it and Google blocking access to its key applications, including YouTube.
Introduced in 2012, the Surface series proved to be a successful line of two-in-one laptops featuring touchscreens and Windows. The series has since seen many versions with vibrant designs.
A disastrous Windows 8-based version released in 2012, Windows RT was designed for ARM processors but suffered from a lack of optimized programs and limited functionality, quickly being abandoned.
In 2013, Microsoft acquired Nokia for $7.2 billion, aiming to bolster Windows Phone. This strategic failure led to the complete shutdown of Nokia's phone division two years later, causing both financial loss and the demise of Nokia's brand alongside Windows Phone.
Beyond these products, Microsoft has made significant investments in AI, developed Captiva, and established its robust cloud system, Microsoft Azure. However, blue screens remain a persistent issue across all Windows operating systems, symbolizing a wave of inefficiency, though Microsoft plans to replace them with black screens.
Microsoft DOS, a powerful yet lightweight technical operating system, significantly expanded access to personal computers and laid the crucial foundation for Microsoft Windows.
