Actually, that's not true. Cygrunsrv knows exactly which service to
start, since the service application can easily retrieve the name of the
service, the parameters, etc. svchost is just lazy, I guess...
Also, "cygrunsrv -S" will not do what you want -- it will send the message
to the service control manager to start the service (which will attempt to
execute "cygrunsrv -S" again, causing an infinite loop).

The fact that it works after boot but doesn't at boot indicates a missing
service dependency (so that the system attempts to start sshd before some
prerequisite is started, while after boot the prerequisite service is
already running). The well-known prerequisites are the Tcp/ip service and
the various firewall services. I'd try those.

Most likely that will work too, but adding the dependency will cause the
service to start correctly the first time.

Look at the "-e" option.

Look at the "-a" option.
All of the information shown by "cygrunsrv --verbose -Q" is stored in
standard ways in the service specifications. If services.msc does not
display that information, then this is a deficiency on the part of
services.msc.

Most likely yes, sorry.
