Registry keys ineffective since Version 13?

It seems that since our update to version 13, the registry keys do nothing to change settings on import;  the main importance of this is to lock the users out of the options via a password, but this no longer happens and I have a lot of cases of this menu being wide open on my host clients;  has this been mentioned before?  I have done several registry key exports and the results are the same.

Please let me know if more details are needed.
