MS Confirms 64-Bit Windows for April

At the Intel Developer Forum Tuesday, Windows head Jim Allchin confirmed that Microsoft plans to deliver final versions of Windows for 64-bit processors in April. The x64 edition of Windows XP is slated for release early next month, with Windows Server 2003 adding support for 64-bit processors by the end of April.
Intel is expected to release its consumer 64-bit processors around that timeframe, including the company's Celeron 64. AMD, meanwhile, has had its 64-bit Opteron and AMD64 chips available since last year. Microsoft has been beta testing Windows for the next generation processors since 2003, and recently issued a second release candidate.
