I upgraded to windows 11 by accidentally pressing spacebar on startup

I always hibernate to avoid waiting an hour for startup.
I'm sorry but wtf, I've been a Windows user all my life, often on old, shitty PCs, but startup never took more than a couple minutes at worst. Sounds like something is really wrong with your PC O.o
