While trying to log in to my BBC Store account on my wife's PC, somehow I ended up replacing my wife's name as User at login (the only account and therefore admin) with my own name and Hotmail address. The named Documents folder has also changed to my name. I have no idea how this happened though it has something to do with me logging into Hotmail on her computer. But how do I rectify this and return the computer to her User name alone. My wife's PC runs on Windows 10 Home.
