How do I uninstall Powershell? It's causing computer games to minimize and programs to hang every minute, making work extremely frustrating and difficult. (I do video game art) How do I get rid of it permanently? I don't want it on my computer at all. It's a useless program. I can't find it in the list of updates or installed programs, but it's there. Please help me guys! This stupid Powershell is just as bad as a virus! I'm fixing to find everything with the word "Powershell" in it and deleting it manually.
