Well over the past month i have been experiencing issues with my pc and im tired of them, one of them is, all my files being removed from admin so i cant use any of them even if i reinstall them, one file is minecraft i have to run it as a jar because of something that happpened and i dont even know, so i know some of you are great with computers like kukelekuuk00, so if any of you could tell me how to factory reset my pc, every time i try it with the disk it says i don't have the disk when i do. So if any of you could post a video or step by step instructions on how to do this that would be great, i'm banned so i have time to fix some things that need fixing. Its a windows 7 pc.
