Remove any services you might have installed ("cygrunsrv -R ssh") and
remove all entries from the mount table ("umount -a") and that should
pretty much do it, assuming of course you removed the main installation
directory as well.

Personally, though, if I were you and trying to fix ssh I'd worry just
about ssh.  Remove the service and any created files (pid, log,
$HOME/.ssh, etc.) and then re-reun ssh-{host,user}-config.  Removing
everything and reinstalling "pristine" is one of those things that
everyone likes to do but it always seemed to me like the equivalent of
crushing the entire car and melting it down to raw scrap steel to fix
the scratch in the side of the door.  But, I will admit, it does work in
a lot of cases (due to e.g. permission errors on the original install.)
