Please help if possible, running Windows 7 Professional, changed the Username under "Add new users to your computer" and now am getting an error message "No mapping between account names & security IDs was done"
I have not put any password into the system, just changed the user name from joint names to a single name.
Scared to reboot as I don't think I'll be able to log on again.
