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 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

1.
Click the
Start
button and click
Log Off
.
2.
When the
Log Off Windows
screen appears, click either
Switch User
or
Log Off

When you select

, the main user screen appears. You can then select your account name
and log in. Your personal desktop appears.
What Happens When a Fast User Switch Occurs?
When a fast user switch occurs, the original user is not logged off the computer as previously happened on
other Microsoft operating systems. On Windows XP, the user's logon remains active, but is replaced by the
new user. Users can switch between login IDs as often as they want.
However, user applications active during a user switch remain active and running in the background while
the new user is working; this can result in a slower computer until the process finishes. For example, if one
user is downloading a large file from the Internet and another user logs on to the computer, the file download
continues in the background until it is complete.
While most applications continue to run in the background during a fast user switch, multimedia applications
