So, whenever I fuck up and accidentally hit a mystery key combo, Windows 8.1 decides that I was trying to Switch Between Apps and this motherfucker shows up on the side of my screen when I alt-tab from its useless app screen back to what I was actually doing. He's not helping, he's not wanted, and I can find no way to dismiss him other than restarting, because I'm on a desktop and I can't actually begin with my finger outside of my screen, you festering fuckwad. Does anyone know how to dismiss this demon from my life for all time? Or just how to get it to go away temporarily. Or anything, really. Please. My crops are dying.
