The Remove Disconnect option from Shut Down dialog machine setting should be configured correctly. This policy setting allows you to remove the "Disconnect" option from the Shut Down Windows dialog box in Remote Desktop Services sessions. You can use this policy setting to prevent users from using this familiar method to disconnect their client from an RD Session Host server. If you enable this policy setting, "Disconnect" does not appear as an option in the drop-down list in the Shut Down Windows dialog box. If you disable or do not configure this policy setting, "Disconnect" is not removed from the list in the Shut Down Windows dialog box. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Remote Session Environment\Remove "Disconnect" option from Shut Down dialog (2) KEY: HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\NoDisconnect
