Moving the entire world's manufacturing processes is not a "little thing to change". Same thing with Active Directory - millions of people work through this system, it's no small task to transition them to something else. It's not doomed as a consumer OS. People want to use the same OS at home that they do at work, it feels familiar to them and they already know how to get stuff done.
