User Accounts and Fast User Switching

NOTE: Fast User Switching is the default user screen for both Home and Professional editions, but is disabled in Windows XP Professional when the computer is a member of a computer domain.

Microsoft Windows XP includes a new feature that provides multiuser access to a single computer. Fast User Switching, which is available in both the Home and Professional editions, allows users to access the computer with their specific settings, including the desktop and various applications, without requiring the previous user to log off. New users log on and switch from the original user’s session to their own. New users can run their desktop and applications without interfering with the original user. When the original user returns, that user can switch back to the desktop and applications with the original settings. All of this is accomplished without the delay of each individual user logging off the computer.

During setup, the computer administrator creates all the accounts that will be used on the computer. (For information on types of accounts and adding new accounts, see “How to Add Users.”) When the computer starts, the main user Welcome screen appears with all of the user names. From this screen you select an account and log in to that session.

How to Use Fast User Switching

To access Fast User Switching, perform the following steps:

1Click the Start button and click Log Off.

2When the Log Off Windows screen appears, click either Switch User or Log Off.
