when using the classic screen though it will default to the last one used. There is "the" administrator account and as many as have been made using this one or other admin accounts. You don't want to monkey with "the" administrator account however. Where you'd go to remove unwanted admin accounts is the control panel under User Accounts. As an administrator or "the" administrator you can manage other admin accounts or remove them.
Sorry couldn't get help on my other question. XP Pro SP3
If there is more than one admin. What tells Windows to open the login box, in classic mode, with what admin.?
I need to delete whatever tells windows as I have already deleted the admin account yet it still insists with opening the login box with that admin.
