setup.exe does not, currently, start (or even install) any daemons. Any
daemon setup is usually done by the corresponding *-config script. Unless
someone writes a postinstall script that will install a daemon (unlikely,
and should be considered a packaging bug), you should explicitly add any
daemons before they are started.

The Windows equivalent of "daemons" is "services". Does that help?

Unless you've added some services, there will be no remote users logged in
via Cygwin programs.

It should be.

It would help more if you described the exact stumbling blocks and things
you didn't find in the docs and had to search for, or even provided
patches to the appropriate parts of the documentation.
