In Vista and Windows 7, to disable showing the last used user ID at login, or to force the use of Ctrl+Alt+Del at login, use the Local Security Policy editor.
Open it from the Control Panel, or by using the command SECPOL.MSC and navigate to "Security Settings", "Local Policies", "Security Options" and find the "Interactive logon" settings in the right pane.

Now enable "Interactive logon: Do not display last user name" to disable displaying the last user name, and disable "Interactive logon: Do not require CTRL+ALT+DEL" to require the use of Ctrl+Alt+Del.
