What is the Welcome screen?
The Welcome Screen is the screen that you use to log on to Windows. It displays all of the accounts on the computer. You can click your user name instead of having to type it, and you can easily switch to another account with Fast User Switching.
The Welcome screen
In Windows XP, the Welcome screen could be turned on or off. In this version of Windows, the Welcome Screen can't be turned off. Fast User Switching is turned on by default.
Note
Fast User Switching is not included in Windows Vista Starter.
