Microsoft Windows XP marks 25th anniversary

Microsoft's Windows XP has reached its 25th anniversary, marking a quarter-century since its production version was released on August 24, 2001. The operating system, which reached retail availability in October 2001, is widely regarded as a milestone in computing history.

Windows XP was significant for unifying Microsoft's consumer and business operating systems by migrating both to the more robust Windows NT kernel. This move replaced the older Windows 9x consumer line and bridged the gap with professional systems like Windows 2000.

Known for its iconic visual elements, such as the 'Bliss' wallpaper and distinct taskbar, the system maintained a remarkably long lifecycle. Despite the release of successors like Windows Vista and Windows 7, Microsoft continued to support Windows XP until April 8, 2014, due to its enduring popularity among users.
