I may have corrupted Windows Update..
Since my computer told me to update, I went to PC settings and ran the update. Then I started Minecraft and within 3 minutes of launching it, Minecraft crashed and along with it Windows Update. I thought that I had extra temporary files, so I ran CCleaner, which deleted temporary files. It ended up deleting Minecraft.exe, but kept the folder for some reason. Of course I reinstalled it and ran Windows Update again, which then kept saying "Update could not install." :/
Can't do much else right now.. Except for look for a possible fix online xD
So.. Alphabutt, get over here xD
