A. Under Control Panel, User Accounts, "Change the way users log on or off," is a simple dialog box that gives you two options (if you're in a domain, you won't have the "Change the way users log on or off" option):
- Use the Welcome screen—With this option enabled, when you first boot the machine, log out, or switch users, the system displays a screen that lists the local accounts and displays user pictures (if you configured the picture option). Also new to the Welcome screen is the ability to have a user password hint.
- Use Fast User Switching—Fast user switching, which works similarly to Terminal Services sessions, lets you log on as another user without having to log off the current session first.
You can also set these two options from the registry under the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon key:
- LogonType—Set to 0 to display the security dialog box; set to 1 to display the new Welcome screen.
- AllowMultipleTSSessions—Set to 0 to prohibit fast user switching; set to 1 to allow switching.
If you're in a domain, changing either of these two registry keys has no effect.
