I recently bought a new computer (left the old one in my car by mistake, and the outdoor heat caused the plastic casing to expand) and moved all my old files over to the new one. Somehow, it ended up sticking a bunch of my files (Desktop, Documents, etc.) in my OneDrive (which was setup without any confirmation that I’d like to use it). I had to create a brand new profile that wasn’t linked to a Microsoft account on my brand new computer and move everything over just to fix the issue.
