Do you mean by "another service startup":
another service (Windows service)
-> an application (not a Windows service)
-> pg_ctl start
Then pg_ctl runs under the Windows service environment, and the popup won't appear.

I experimented it with a sample program that I showed in this thread. A program invoked by a Windows services also runs in the service.
