Microsoft does have to support their OS on a far wider variety of hardware. Same with Android from Google. Apple has the advantage that they only have to write code that works on their exact special hardware and basically nothing else, which is also dumb because they don't let you even run a macOS VM to compile programs for macOS. Apple just expects everyone to bow to them. That being said, Microsoft is awful and lazy as hell. Each version of Windows makes slight improvements but adds another layer of GUI cruft and complexity by adding new features to replace old features which they don't actually replace, and everyone who works there definitely eats crayons as you said.
