I recently had my computer repaired at Best Buy and it returned working well but a new "Administrator" account was added even though I already gave them the password and such for my own administrator account. This account is seriously bothering me. I cannot get rid of it for the life of me. I repeatedly attempt to remove the account but when I go into Add/Remove account and manage the account, the only option missing is "Delete the Account". Why is this and how can I make it an option?!?!
