Windows XP for 64bit Itanium based systems

Released on March 2003, this version of Windows XP saw maybe the shortest lifecycle of a Microsoft operating system ever. In June 2005, Microsoft abandoned support for this version of windows, which was prior marketed via OEMs for Itanium based Workstations.

With HP cancelling the last line of Itanium Workstations, XP IA64 was canceled.
