windows xp automatically remove temporary profiles on logoff

Question

I am partly managing a school which uses temporary local profiles. (NOT server-saved profiles). The computers are automatically getting restored regularly, but inbetween alot of temporary profiles gather on the computers, sometimes even completely filling up the hard drives, which turns to a real problem then.

How can I automatically delete the profile when a user logs out?

Edit:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\DeleteRoamingCache does only remove those "server-saved" roaming profiles.
Also, deleting the profiles just on startup using delprof or such is a sub-optimal solution which I would rather not like to use. It should be removed just when logging out.

Answer 1

You can make them Mandatory profiles. This should erase them after they log off.
