How about just using Software Restriction policy to deny that setup exe from running? I think the way you’ve described to prevent an install sounds kinda screwy, to be honest.

That is by adding a ccmsetup key under hklm, but the permissions should be set that the installation gets access denied when pushing the client. I am using desktop standard to. Create that key and it works. The only problem is that it it inherits parent permissions. I can fix the permission, but once I reboot the test client it reverts back to administrators, crearor owner, system etc. I would greatly appreciate if you can help please.

You can’t have no permissions on a key. In that case, it will always fall back to some default set of permissions. What are you really trying to accomplish?

What I am trying to do, if it is possible, is to even get rid of all permissions on the key I am adding.

If you don’t—that is, if you want to break inheritance completely with the parent keys, then you choose “do not allow permissions to be replaced”. If you do, then you choose the first option and then within that, whether you want your permissions to be inherited downward or not.

This is where my dilemna is.

You can use Group Policy’s built-in registry security capability or you could use a combination of a startup script (assuming the key is under HKLM) and a utility like subinacl.exe to do it.
