I'm not sure if this is the right forum but I can't seem to find any other place for this question. Someone had my computer for over a year while I was away from home and I'm trying to figure out how to wipe out my computer while keeping the OS. I looked up on Google and it said it wasn't possible but I feel like there must be a way. I just want a clean start with nothing from previous users.If anyone could tell me how to clear my pc without deleting my OS that would be great.
