Microsoft Windows

Microsoft Windows is a family of proprietary graphical operating systems developed and marketed by Microsoft. First introduced in 1985 as a graphical operating system shell for MS-DOS, it has since become the dominant operating system for personal computers globally. The software is developed primarily at Microsoft's headquarters in Redmond, Washington, though development efforts involve global support teams and data centers.

Over the decades, Windows has evolved through numerous versions including Windows 95, XP, 7, 10, and 11, expanding from home computing into server markets and cloud-integrated services. The brand's origin is tied to the early personal computing revolution and the rise of Microsoft as a global technology leader. Today, Windows remains a core product of Microsoft Corporation, serving as the foundation for both consumer productivity and enterprise-level infrastructure across the world.
