I might not be sure what the "None" selection under Autologon is supposed to, but if I choose "None" (logon count is 0), it still logs on once as the (renamed) administrator account. Furthermore, it adds the following lines to winnt.sif: AutoLogon="Yes" AutoLogonCount=1 Removing these lines do not seem to have any effect. I don't want it to auto-logon, but I do want to change the name of the Administrator account. Is this possible? Or did I stumble on a bug?
