Thanks, chilifrei64 We have used scripts and NT4 policies for all kinds of registry settings earlier. Some of the registry keys I want to delete is in the HKLM and therefore I can't run them in a logon script. I did hope that when I did put the computer in the right OU it would automaticly configure itself with the registry changes I need. The back-up plan is to make a script that resides on the DC:s and let a machine policy run it.
