Windows Server 2003 is available in both 32-bit and 64-bit versions, but Microsoft doesn’t plan to conserve the 32-bit/64-bit split approach for very much longer, if a report by APC Magazine is to be believed. The magazine says the next version of the server variant of Windows, which Microsoft recently dubbed Windows Server 2008, will be 64-bit only. “All future operating systems for server hardware from Microsoft beyond Windows Server 2008 will be 64-bit,” APC Magazine quotes Microsoft senior Windows product manager Alex Heaton as saying.
On the desktop, things are less definite for Microsoft. Vista is available in both 32-bit and 64-bit flavors, and Heaton points out that there is a “growing community of drivers for 64-bit Windows Vista.” However, he adds, “we have not decided when Windows Client will follow Windows Server and become 64-bit only.” The VP of Development for Microsoft’s Windows Core Operating System Division stated back in February that the next client version of Windows is scheduled to come out by the end of 2009.
