Run gpedit.msc to open the Group Policy Editor and navigate to the following setting:
User Configuration > Administrative Templates
Here you will see Policy settings for Control Panel, Desktop, Network, Shared Folders, Start Menu, System and more. If you receive this message when you open any elements, you may have to check the settings here and find out if any of them have been Configured. For instance, if you receive this message when you try to open the Command Prompt or Registry, you will have to disable the Prevent access to the command prompt and Prevent access to registry editing toolssettings respectively.
