You need to be an admin to create anything under the Policies key !

The above setting for example hides drive c: and drive X: from certain user groups. I only want this to apply to certain groups. Works fine if a local admin, but won't work as standard user because standard users on windows 7 cannot create subkeys under the policies key. Hence the question.
