Unless you are running some service (like sshd), no Cygwin program starts
with Windows boot.  Unless you took steps to enable such a service, you
won't have one running.  By default, no Cygwin program starts with boot
or login.  You have to start Cygwin's shell through the BAT file or run
some program explicitly from cmd.exe.  Entries in the registry are benign
and ignored by everything but Cygwin.  If you're curious, run cygcheck -s
-r -v to see Cygwin's setup, including registry entries and environment
variables.
