On a MacIntosh computer you can set up the account preferences so when the 
computer starts up it will automatically sign into a specific account when 
multiple user accounts have been set up.

Is this possible to do on a PC running Windows XP?

For example:

the accounts on my computer are:
Mom
Dad
Tom
Sue
Guest

On a windows restart it will reboot & then wait for me to "select" which 
account I want to go into.

(When I am troubleshooting especially) I want the computer to reboot & then 
automatically go into the Mom account - because it has the administrative 
privileges.

TIA for any help.
