A cat walking on my keyboard a couple of days ago opened Copilot and now the fucking thing starts up every time I turn on my computer. 
Can you uninstall it from the start menu? Alternatively I found this thread with some other solutions
According to someone in that thread, it just comes back after updates when they uninstall, so I'm not going to waste the effort. Did find the start-up apps list and disabled it from auto-start-up. (Apparently, I have two Copilots. The base default one and the 365 one. The second was the one that was starting.)
ugh
