Do this; CONTROL PANEL->ACCOUNTS...take a look there and see if anything you can change there. Good luck.
When I update from 8.1 to 10, the Windows login first showed my name and then my email address below it and I was only person listed. About a week ago, the login shows the email address where my name was and the email address below it and there is a second person showing in the lower left corner. No name but my email address for it. Microsoft controls updates. Have run Malwarebytes with no problems found.
I'd like to repair and get on with using the laptop.
Thanks,
