If we're speaking strictly in regards to UI, then this is not a problem unique to Windows. I mean, would you not agree that Ubuntu's implementation of Unity changed the GUI a considerable amount compared to previous versions?
The difference is that in the world of GNU/Linux, a different desktop
environment or window manager is usually just a single package manager
command away. You're being free to choose. Microsoft will force their UIs on
you, and there's nothing you can do about it (except not updating, which is a
workaround, not a solution).
