That'll work only if there is only one user account.
More than that you'll get the Welcome Screen with a panel of users for you to select to logon.
I suspect that your friend has D/L the .Net Framework Update which automatically creates another user thus triggering the logon screen.
Check in User Accounts and see how many users are there.
BTW, TweakUI for XP allows you to set XP to automatically boot straight into a User Account of your choice.
It's the Logon item. Click the "+" and click Aotologon and follow the instructions.
A relative using Win XP Home Edition is receiving the Login Screen requesting a User Name and Password. She doen't know how this came about and wishes to eliminate the login procedure. I am uncomfortable working with user accounts and need simple instructions to give her. I see on another forum the following but am unsure if this is a valid solution and fear locking her out of Windows:
"Try going to the Control Panel, User Accounts. Then click to change your Account, and to create password. Just clear the password box, and leave it blank and save. Think that might fix ya up if I remember right."
Comments and instructions appreciated!
