My C drive had too much space left over, so I moved the Users folder to my D drive and changed some settings in the registry. After restarting my computer, I signed into my work account and checked that everything looked fine. Everything was okay there. Then I tried logging into my personal account by pressing restart again, but it said: The User Profile Service failed to start. User profile cannot be loaded. It won't let me log in right now, even after a full restart. There are no backups or restore points here either. Someone could help me out?
