This policy setting prevents users from running the interactive command prompt Cmd. exe. This policy setting also determines whether batch files (. cmd and . bat) can run on the computer. If you enable this policy setting and the user tries to open a command window the system displays a message explaining that a setting prevents the action. If you disable this policy setting or do not configure it users can run Cmd. exe and batch files normally. Note: Do not prevent the computer from running batch files if the computer uses logon logoff startup or shutdown batch file scripts or for users that use Remote Desktop Services.
