Microsoft has decided to delay three upgrades to Windows, because the company has fallen behind schedule. The 64-bit Extended System versions of Windows Server 2003 and Windows XP are moved to the first half of 2005. Also delayed to the first half of next year is the Windows Server 2003 Service Pack 1, which was planned to be available later this year.
The Windows Server 2003 and Windows XP for 64-bit Extended Systems are designed for 64-bit chips from AMD and Intel that have the ability to process in both 32-bit and 64-bit modes.
Windows Server 2003 Service Pack 1 will feature improved security, reliability and performance.
