Default Behavior
The Terminal Device Driver service is a kernel mode driver. If Terminal Device Driver fails to start, the error is recorded into the Event Log. Windows Vista startup proceeds, but a message box is displayed informing you that the TermDD service has failed to start. At least one service depends on Terminal Device Driver. Therefore I do not recommend you to disable it.
Dependencies
If Terminal Device Driver is stopped, the Terminal Services fails to start and initialize.
