How do you remove the stand by and log off options from the shut down combo menu. I'd rather students shut down than leave the pc ready for the next person to log in and it also mean I can run psshutdown (if pc logged in) as this don't work with the login screen showing. Ian

You may be able to do something with scripts look at this http://support.microsoft.com/default.aspx?scid=kb;en-us;198642 and http://support.microsoft.com/default.aspx?scid=kb;en-us;322241

You don't mention your environment details, so this is just local policy but you can do the same with group policy. Start>run>mmc Cosole>Add/remove...>Group Policy This gives you settings to be applied to people on this workstation. Go to user configuration>Administrative templates>System>Logon/Logoff Enable to appropriate policies here and under "user configuration>Administrative templates>Start menu & taskbar".
