So today something weird happened when i launched my PC. At login screen i've noticed that a new account has been made called "Administrator". Wasn't certain if it was made after Win update or something, but i am sure i did not create it myself. I wanted to check out what it is, and clicked to login on that account. Account did not have password, and PC just got stuck at loading screen. After i forced computer to shut down, everytime i launch it, it tries to automatically login to that "Administrator" account, and since it has no password, computer just gets stuck again and again on loading screen. I have no idea what is going on or what i can do besides reinstalling windows, which i would really want to avoid. Is there any way to stop the autologin function?
