Nope. Because the goal was to make it as seamless as possible to port software to those platforms, ideally by just recompiling with a different flag. The offerings would be DOA without dev buy-in which wouldn’t happen if there was too much friction in porting.
It's not like they haven't tried it - Windows RT and Windows 10S have largely flopped. You could say this is because of the other changes trying to put the MS store as a required middle man, but both boil down to users rejecting Windows when it doesn't run all their existing software
