The primary issues that I faced with Windows (Win10 nearly a decade ago) are
very slow updates
constant 100% disk usage after boot
high background process usage
[Rare] messing with my dual partition setup
The final error which caused me to format my PC -> After logging in, the desktop froze, no icons showing up, no task manager.
If I had never used Linux, these wouldn't even seem like problem; just normal Windows shenanigans. But after using Linux, I can never go back. I don't know how much worse/better Win11 is now but can't be bothered to try.
