WoW64 stands for "Windows on 64-bit Windows", and it contains all the 32-bit binary files required for compatibility, which run on top of the 64 bit
One nice thing about x64 systems is that you can use either Win32 or Win64 on the same machine without serious performance losses, unlike Itanium-based systems. And despite a few obscure differences between the Intel and AMD x64 implementations, the same x64-compatible build of Windows should run on either. You don't need one version of Windows for AMD x64 systems and another for Intel x64 systems. |
