Microsoft WindowsEdit

Microsoft Windows is the flagship family of operating systems developed by Microsoft that powers a substantial majority of personal computers and many business servers around the world. Since its inception, Windows has evolved from a graphical shell that ran atop a DOS environment to a comprehensive platform with its own kernel, security model, development stack, and extensive ecosystem. It has shaped how people work, play, and interact with hardware, and it remains a central piece of the information technology infrastructure that underpins modern commerce and productivity.

From a pragmatic, market-driven perspective, Windows is notable for its relentless focus on compatibility, developer reach, and a broad device footprint. The platform’s success rests on a large base of software written for its APIs, a deep commitment to backward compatibility, and a large ecosystem of hardware partners and enterprise customers. Proponents argue that Windows creates an efficient engine for economic activity by lowering the costs of software development, deployment, and IT management across consumer devices, corporate desktops, and server farms. The result is a platform that supports everything from small business desktops to large data centers, and from educational labs to gaming rigs. Microsoft Windows DirectX Win32 API NTFS
