History

Windows began in 1985 as a graphical shell on top of MS-DOS and became the dominant desktop operating system with Windows 95. Windows XP (2001) moved home users onto the more robust NT kernel that every version still uses. Since Windows 10, Microsoft ships yearly feature updates rather than big new versions every few years. Each update is supported for 24 months on Home and Pro editions and 36 months on Enterprise and Education. Windows 10 reached end of support in October 2025, with paid Extended Security Updates available after that.
