SYMPTOMS
The performance of Windows XP may slow down as additional users log on to the computer.



CAUSE
This issue can occur if the Fast User Switching feature is enabled and users remain logged on and leave programs running.



WORKAROUND
To work around this behavior, free some resources in Windows XP. To do this, use any of the following methods (use the first method if you can):
 * Log off users individually:
 * Log on with administrator permissions.
 * Press CTRL+ALT+DELETE to start Windows Task Manager.
 * In Windows Task Manager, click the Users.
 * Click a user, and then click Logoff.
 * Restart the computer. Note that this logs off all users.
 * End processes that are being used by other users. Note that this method may cause unexpected problems.
 * Log on with administrator permissions.
 * Press CTRL+ALT+DELETE to start Windows Task Manager.
 * Click a process, and then click End Process.



STATUS
This behavior is by design.
