Windows XP x64 Edition is a Windows XP Professional Edition written for the Systems that support the EM64T and x86-64 64-Bit Instruction Sets. There was also a version produced for IA-64 systems, namely the Intel Itanium, but that was dropped, instead focusing Windows Server 2003 for that platform.
Windows XP x64 Edition will not be available as a Retail version. Instead, it will only be available as an OEM release. There is a Technology Trade-up on offer to trade in an existing 32-Bit Windows XP Professional Edition License, for a 64-Bit Windows XP Professional x64 Edition License.
