This is a layer of code in 64-bit versions of Windows that allows a file with a PE32 (32bit) header along with x86 instructions to run under a 64-bit address space, there by providing backward compatibility. This technology even allows 32-bit applications with x 86 native codes in them to run on an Itanium machine, because theWoW64 technology can emulate the x86 instruction set; albeit with a significant performance cost.
Basically
WOW64 = Windows On Windows64
In fact you can find a good indicator of this by looking in your WINDOWS directory where now you will not only find the misnamed SYSTEM32 directory (which holds the 64bit dll’s for the 64bit OS) but also the SYSWOW64 directory which holds 32bit versions of dll’s for the virtual 32bit OS.
