Other start_type values:

0x00000002: A service started automatically by the service control manager during system startup. For more information, see Automatically Starting Services.

0x00000000: A device driver started by the system loader. This value is valid only for driver services.

0x00000003: A service started by the service control manager when a process calls the win32_start_service() function.

0x00000004: A service that cannot be started. Attempts to start the service result in the error code 

0x00000001: A device driver started by the IoInitSystem function. This value is valid only for driver services.

I can confirm that 0x00000003 works as expected (service is created, but must be started manually).
