There's not much to emulate but it's still there, I've spotted plenty of stuff labeled Windows-on-Windows or WOW64 digging around Win7 installs. While it may not be doing CPU emulation (IIRC they just use the 64-bit registers like 32 and remap calls) but it is emulating nonetheless.

If memory serves, WOW64 translates system calls and allows 32-bit apps/APIs to interoperate with 64-bit apps/APIs.

Which is still a pretty good trick, at least when it works.
