It isn’t even just the performance and bloat issues or the AI.
As you hinted, Windows 11 made a lot of changes to the UI. I can’t think of a single change made which I liked as someone who has had to deal with Windows since before 95. Windows 11 felt like a downgrade from Windows 10.
You’ve got a lot of managers with purchasing authority who developed a ton of muscle memory on old Windows. The new UI changes have made Windows feel alien enough that you can’t use retraining costs as an excuse to keep with Windows.
Windows 11 UI is a downgrade from XP.
Windows 11 is also deeply unstable. I haven’t had this many program crashes, errors, and other bullshit since Vista and ME. Windows 10 had it’s annoying quirks but it was at least relatively stable.
I have saved myself the headaches with UI changes since the Win8 clusterfuck when installed a 3rd party taskbar/menu.
