If you changed a users name in Control Panel/User Accounts, this only
changes the name of the account. The name on the files that belong to that
account cannot be changed.
I tried to fix this problem by creating the user name I wanted and deleting
the other one but now the system is asking me to validate my copy of windows
and using the one listed does not work.
