32-Bit or 64-bit OS ??

By , 10 Aug 2011
 

WOW64 is the x86 emulator that allows 32-bit Windows-based applications to run seamlessly on 64-bit Windows. WOW64 is provided with the Operating System and does not have to be explicitly enabled. A 32-bit application can detect whether it is running under WOW64 by calling the IsWow64Process[^] function. The application can obtain additional information about the processor by using the GetNativeSystemInfo[^] function.

WOW64 is NOT an x86 emulator; there is no need for such emulation: the 64-bit Intel or AMD chip includes one or more 32-bit as well as 64-bit CPUs, there is no need to emulate the 32-bit instruction set, registers, or programmer's model. What WOW64 does is emulate a 32-bit version of Windows, as if an actual 32-bit Windows XP/Vista/7 were present.

I guess this should be a comment, since both functions are already mentioned in the original tip.
