It's WOW64, like Itanium and AMD64. The former also used an emulator, whereas the latter is hardware of course.

- my123 9y agoActually, ARM64 Windows uses double-WoW64. Two WoW64s are running at the same time - one running ARM32 code - and another x86_32.
- TazeTSchnitzel 9y agoYep! I was aware of that but didn't mention it. I wonder if WoW64 had to be modified to support having two architectures. Though they maybe planned ahead: it's "Program Files (x86)", not "Program Files (32-bit)" :)
