I had occasion to employ Toshiba to remove some malware from a Toshiba Satellite laptop. Some time later I needed to uninstall an Ap and discovered there was need for a Supervisor password. I am assuming the tech set that up (why?) as I had installed considerable Aps earlier without needing a password. I logged on to the Toshiba Tech chat, explained the situation and was told "So Sorry" with no help in resetting. How can I reset the Administrator password to none required?
