Windows 10 can run on 64-bit ARM CPUs. The operating system's
%PROCESSOR_ARCHITECTURE% environment variable shows
ARM64 - meaning that its a 64-bit operating system running on ARM. This operating system can run 64-bit ARM applications, plus it can run 32-bit ARM applications (
ARM) and 32-bit IA-32/x86 applications (
x86) through the Windows on Windows (WOW) compatibility/emulation layer.
Windows also released a few 32-bit ARM operating systems. The recent ones I know of are:
- Windows RT (Windows 8 / Windows 8.1 on ARM)
- Windows 10 Mobile
- Windows 10 IoT Core
- (there may be others; if I am missing any, please drop a comment!)
My question is: can any of the 32-bit ARM operating systems run Intel IA-32/x86 applications through the WOW compatibility/emulation layer? If so, which? Or do all 32-bit ARM Windows operating systems lack a WOW subsystem for these x86 applications?
(I know that Windows RT does not support any x86 applications, but I am not sure about the others. I'm also not sure that my bulleted list is complete)
