Disabling the Welcome Screen
On computers running Windows XP Professional that are not members of a domain, the default is for users to see a Welcome screen that includes the names of all users with accounts on the computer. The user’s password prompt is revealed when the user clicks his or her name. Because the names of all user accounts are made visible on this Welcome screen, this behavior is less secure than using the Ctrl+Alt+Del user interface.
To disable the Welcome screen and require CTRL+ALT+DEL to be used for logons
1.
In Control Panel, click User Accounts.
2.
Click Change the way users log on or off.
3.
Clear the Use the Welcome screen check box. This also disables the Use Fast User Switching option.
Users will now log on using the Ctrl+Alt+Del user interface.
