Yeah.. it didn't take me long to see my initial mistake of the 0 instead of 1. But even after that, the restriction failed to implement. I do know that it is not a problem accessing the HKCU durning boot up as a few other restrictions use the same key to issue restrictions and they have worked. Plus I have also gone into the regedit on my test machine to find that it has indeed written the value to the key. However, I never have tried a complete reboot of the system and log in to see if that might work. Think I'll give that a shot right now.
