Windows XP Professional x64 Edition - now available (free upgrade)

Windows XP

Windows XP x64 debuted on April 25, 2005.  There is still much work ahead before the Windows 64 bit environment becomes mainstream, but it's now a product available for x64 PCs.  Hardware vendors will need to write 64 bit APIs and applications must be reengineered to take advantage of the native architecture.  Still, this is a noteworthy advancement by Microsoft and provides a promise for the future for PCs built around AMD x64 and Intel x64 technologies.  Microsoft is also offering a free upgrade to existing XP users on the x64 PC platforms, which is good through July 2005.
