Microsoft Windows XP was a hugely successful version of Windows. The operating system, with its vastly improved interface and capabilities, helped fuel phenomenal growth in the PC industry in the early 2000s.

Windows XP was put into manufacturing on August 24, 2001, and released to the public on October 25, 2001.

Windows 2000 and Windows Me were the predecessors, and Windows Vista was the successor.

April 8, 2014 was the last day that Microsoft released security and non-security updates for Windows XP. Now that the operating system is no longer supported, Microsoft recommends that users upgrade to the latest version of Windows.
