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:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon \ SpecialAccounts \ UserList
Create the following entry:
Username: REG_DWORD
(Where Username is the username of the user you want to hide from the Welcome Screen ).
Assign a value of 0.
Close Registry Editor.
Reboot.
This will prevent the user from showing up on the welcome screen. you will need to press the CTRL-ALT-DEL twice at the logon screen to get the old W2K logon style box to be able to log on to the account you 've ve den. 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.
