The 64-bit versions of Microsoft Windows Server 2003 and of Microsoft Windows XP use the Microsoft Windows-32-on-Windows-64 (WOW64) subsystem to run 32-bit programs without modifications.

The WOW64 subsystem creates a 32-bit environment on the x64-based versions of Windows Server 2003 and of Windows XP Professional x64 Edition. Some 32-bit programs may run slower on these operating systems than they would on 32-bit versions of Windows Server 2003 and of Windows XP. For example, a 32-bit program might run slower on Windows XP Professional x64 Edition than it would on Microsoft Windows XP Professional. Alternatively, some 32-bit programs that require lots of memory may exhibit increased performance on the x64-based versions of Windows Server 2003 and of Windows XP Professional x64 Edition. This performance increase occurs because the x64-based versions of Windows Server 2003 and of Windows XP Professional x64 Edition support more physical memory than the 32-bit versions of Windows Server 2003 and of Windows XP Professional.
