Most of the original x86_32 patents have now expired, that was sufficient to let Microsoft build the emulation layer for WoA.
It might be more feasible now, except in the last ~5-10 years there's been a push to make many PC apps x86_64 only (e.g. Ubuntu dropping i386 support), so the benefit isn't quite as wide any more.

- mappu 7y agoPresumably so, or Microsoft would have extended the WoA compatibility to x86_64 as well.
