How can I hide a user from the Welcome Screen in Windows XP?
To hide a user's account from the welcome screen in Windows XP:
Open Registry Editor.
In Registry Editor, navigate to the following registry key:
Create the following entry:
(Where Username is the username of the user you want to hide from the Welcome Screen).
Assign a value of 0.
Close Registry Editor.
This will prevent the user from showing up on the welcome screen. You will need to press CTRL-ALT-DEL twice at the logon screen to get the old W2K logon style box to be able to logon to the account you've hidden. Adding a username and setting the value to 1 will cause that user, such as Administrator, to show up on the Welcome screen as well.
