I have heard disturbing stories from tech-illiterate windows users complaining about forced upgrades, reboots—even fullscreen Office365 ads. It's a pain to be "the computer guy" for windows users. They need help constantly and for silly things that has changed place or behaviour. I also do support for tech-illiterate linux users on Fedora and they never call or have trouble. It just works, even with auto-updated flatpaks enabled.
I'm not even tech illiterate (I used to work at Microsoft!) and I was thrown off by the fullscreen Office365 ads they added around 2019. The shortcut was just "all of your modifier keys" so it got activated randomly when I picked up my keyboard by the corner and it took me a bit to track that down. Think I had to fix it with a registry key. It's fucking nonsense and it's really no mystery why users don't want automatic updates.
Yeah ton's of memes out there by windows users who were forced to upgrade 5 minutes before a meeting or something. It's a real issue. It's why I leave my office laptop on all night, so they can do their stupid forced upgrades in the middle of the night like they schedule them. I have too many meeting to wait for a 30minute - 1 hour update popping up unexpectedly.
