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.
