Wondering if anyone has found a variable that Group Policy will accept that can be used as an entry in the Approve Locations to display only the Drives under My Computer and nothing else? I have turned on "Restricted Browsing" but any variable I try for Local drives or My Computer does not work. As a test I have placed just a network drive in the Approve locations and this is displaying but as expected nothing else.

We are trying to restrict users to only the mapped drives they may have and nothing else. Any help would be greatly appreciated.
