Service Packs
The RTM version of Windows XP Professional x64 Edition is based on Windows Server 2003 Service Pack 1 codebase, as seen in System Properties applet in Control Panel. Because Windows XP Professional x64 Edition comes from a different codebase than 32-bit Windows XP, its service packs are also developed separately. For the same reason, Service Pack 2 for Windows XP x64 Edition, released on the March 13, 2007, is not the same as Service Pack 2 for 32-bit versions of Windows XP. In fact, due to the earlier release date of the 32-bit version, many of the key features introduced by Service Pack 2 for 32-bit (x86) editions of Windows XP were already present in the RTM version of its 64-bit (x86-64) counterpart. Service Pack 2 is the last released service pack for Windows XP Professional x64 Edition.
