Also, you could (and probably should) use a group policy to disable locking
the workstation at all.
If the machines are standalone, run gpedit.msc - it's under User
Configuration/Administrative Templates/System/Logon/Logoff - there are ways to
copy the settings from one computer to another, if you look it up) If they
are in an Active Directory, you should set it up from the server end.
For a classroom setting, you should probably be locking down a lot of things
in there (desktop wallpaper, IE settings, etc etc etc).
Just make sure you read up some on how to use group policies and what the
settings do - if you do it wrong, you can end up locking out the administrator
from doing things, too.
|I am not aware of a means to change which button is the default. However,

|(you did not say if these workstation are part of a workgroup or a domain),
|right click the task bar. From Taskbar and Start Menu Properties, go to the
|Advanced tab. In Start Menu Settings at the bottom of the Advanced Page,
|Display Logoff is the third item down. Check that check box, then choose

|And, of course, tell everyone to choose log off from the Start Menu.
