Windows XP was succeeded by Windows Vista. The most recent version of Windows is Windows 10 which was released on July 29, 2015. April 8, 2014, was the last day Microsoft issued security and non-security updates to Windows XP.

In 2004 and 2005, as a result of investigations into market abuses, Microsoft was separately ordered by the EU and the Korean Fair Trade Commission to make available editions of Windows XP in those areas that did not include certain bundled features like Windows Media Player and Windows Messenger. In the EU, this resulted in Windows XP Edition N. In South Korea, this resulted in both Windows XP K and Windows XP KN.
