TheServiceHostInfo..::..PresetDeviceID Property
   Set this Guid if you want your device to have a predefined DeviceID. If no DeviceID is
   specified, the C-DEngine will create a random DeviceID and stores it at the very first startup.
   Any subsequent system starts use this same DeviceID.
   If UseRandomDeviceID is set, the C-DEngine will not store this ID.
