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