The last time Microsoft made an ARM version of interactive/desktop Windows (Windows RT for the Surface/Surface 2), it didn't support legacy Win32 apps (native or x86 emulated). It was a huge flop; Win32 apps are still the overriding reason why anyone runs Windows.

And now that Intel has gotten its act together with low-power SoCs, I don't see desktop Windows coming back to ARM any time soon.

(yes, there is Windows 10 for ARM but only for IoT platforms, it doesn't support graphical apps)

The Windows RT Surface was a big flop for a lot of reasons. Telling developers it had an iPad store model when the x86 version didn't was probably a bigger problem.
