Already turned the computer on and off, didn't fix it.
So I fixed the icons by rebuilding the windows icon cache.
But now this happened, see those two little white lines on the bottom left? That's the windows 10 start menu icon. The task bar randomly shoved itself down there for some reason, and no auto hide is off and it's never been on. This is not exactly the experience I was expecting when I downloaded this. Is this in beta or something?
Turned the task bar green.
