I use windows at work, it's basically the same except for looks. I do development and have a weird setup and it didn't break after I unexpectedly updated to windows 11 by accident (nobody told me I was added to the list of people being updated). File manager is worse imo but you can still get to the old options menu, they're just buried down a layer.

The system clock no longer shows seconds when you click on it which is annoying.

It's like a modern version of the worst parts of Vista.

The UI is a clunky mess. I had to spend a week to make it about usable. Every menu is now a submenu of a new new menu, so you often have to click 3-4 times for stuff you'd have in a top-level right click menu not so long ago. Now they've been doing that for a while now, so some settings are getting quite deep at this point. The whole thing feels unresponsive and sluggish.
