Use Group Policy to allow Windows logons by administrators, for remote access

We want to allow administrators (only) to use Windows logon for connections.  If I go to Options >> Security >> Windows logon and select Allowed for administrators only,

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\TeamViewer\Security_WinLogin is created with a DWORD value of 1.

I did not see other differences.  Are any other changes made when you setWindows logon to Allowed for administrators only?  We want to push the change with Group Policy.
