Why are you doing these things?  Are you following somebody's "guide"? 
Please tell them that they are spreading useless information if that is
the case.  ntsec is the default.  binmode is the default and is
irrelevant for files anyway.  So "" is the same as "ntsec binmode", and
you should not need to set CYGWIN at all in general unless there is a
*specific* reason that calls for it.

rsync only tries to set the owner when it thinks it has the privilege to
do so -- on most POSIX systems this means being the superuser, uid=0. 
This check in rsync is less than useful on Cygwin where privileges work
differently.  Thankfully they provide an override in the form of the
--super switch.
