Limiting Control Panel access with group policy

You can manage your users' access to the Control Panel through group policy. You can allow/restrict all, or you can pick and choose individual items for user access. The policy to set is found under User Configuration->Administrative Templates->Control Panel in your group policy object.

If you do want to pick and choose individual control panel items, Microsoft has assembled a quick reference list to all the included .cpl files. You can find that list in KB 149648
