Prohibit Task Deletion Prevents users from deleting tasks from the Scheduled Tasks folder. This setting removes the Delete command from the Edit menu in the Scheduled Tasks folder and from the menu that appears when you right-click a task. Also, the system does not respond when users try to cut or drag a task from the Scheduled Tasks folder. Note: This setting appears in the Computer Configuration and User Configuration folders. If both settings are configured, the setting in Computer Configuration takes precedence over the setting in User Configuration. Important: This setting does not prevent administrators of a computer from using At.exe to delete tasks.
