Vista - Can't remove items from DEP Program Exception List

Has anyone else had this problem. I have added numerous programs to the DEP
exception list to make them work and they all worked fine. The problem is,
now that i have uninstalled a lot of these programs they don't need to be on
the DEP list anymore but it won't let me remove them. I click remove and the
program disappears and then i click apply and leave the menu but even after a
restart the items just reappear. Any ideas?

Solved the problem. Don't know why but it won't let me remove programs from
the DEP exception list after i have uninstalled them. I just had to reinstall
every program in the list and then remove them from the list and uninstall
them all again. Note to others just in case you have the same problem, remove
programs from the DEP exception list before uninstalling them, you'll save
yourself a lot of time.
