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.
