In preparation for the upcoming release of Mists of Pandaria, updates to World of Warcraft will no longer support Microsoft Windows 2000. Microsoft ceased support for this version of their operating system in 2010. Players still using Windows 2000 are encouraged to upgrade prior to the release of Mists of Pandaria.
