Windows runs in more places than it probably should. And the OS is just fine on other platforms. Windows on ARM works quite well. As I understand it, it worked just fine on Itanium. NT launched with support for PowerPC. I'm sure RISC-V support will be there pretty quickly. NT was designed for this sort of portability. Most user software is not ready for the transition. Microsoft doesn't impose the same kind of control over its application ecosystem as Apple does. This prevents Microsoft from being able to make architectural shifts like Apple has. Arguably, this more open and flexible ecosystem (and bending over backward compatibility) has been one of the driving factors in Windows's popularity over MacOS. I have no strong opinion about which is a better business strategy.
