Just to clarify, I am talking about UX, not just UI. I use Windows 7 (classic style) at work and it's doable.
- Loads of things in the start menu that I don't need and cannot uninstall (like XBox games).
- Unwanted monitoring which needs to be explicitly turned off.
- Forcing Edge down my throat at every opportunity.
- Automatic updates still restart computer without warning.
- Unwanted wi-fi communication even in sleep causing huge battery drain.
- Ugly appearance.
I am sure there are other things that bothered me but I already forgot. They really lost their marbles.
