I've seen this.

I have also done this.

I haven't really understood Windows since XP died. I understand it even less since I started using Linux. All I know how to do is power cycle the machine a couple times. Which tends to fix a lot of things, not just Windows and not just PCs. If a reboot doesn't help, all I'll tell you is to ask someone more knowledgeable about Windows than I am, or reinstall the whole damn thing.
