Windows 10 is not a bad OS
However, what makes me loathe it are :
- forced updates/upgrades with no way of choosing what is applied
- forced, invasive telemetry
- unique advertising ID - so far you can disable its use for advertising but it will not be deleted
- forced login into MS ecosystem - it is becoming increasingly difficult to avoid it
- "I can't do that, Dave!" behavior - you are not allowed to uninstall what Microsoft doesn't want you to uninstall
All symptoms of a walled garden that's coming. I don't want that for my personal use.
For business use, I don't quite care since I'm being paid to use it.
