Switch User” feature was introduced in Windows XP which allows one user to switch to other user without ending the current session. Its a very useful feature and also available in Windows Vista and 7. Many system administrators might want to disable this feature to restrict end-users. If the users are using Windows XP, its very easy task. You can disable “Switch User” option using “User Accounts” applet in Control Panel.
But its not that easy under Windows Vista and 7 as there is no such option available anywhere in Control Panel. So how to disable “Switch User” option in Vista and 7?
