Hi, Stephen.  First off, <http://cygwin.com/acronyms/#PCYMTNQREAIYR>.
Thanks.  Secondly, attaching a BMP file to show the output of a text-only
program is pretty wasteful (not to mention bothersome to open).  More
below.

I believe what Dave meant was that you cannot update Cygwin using dpkg.

Eh?  I don't see this in your screen dump.  All it says is that you will
be unable to *install* the packages, only preview the available
selections.  Looks like that's exactly what you want to do as you stated
above.  I also don't see any mention of the root user.

Please let us know what the exact error message was, and why it made you
think you needed root access.

I see no error -- only an informational message that no packages can be
installed (but you didn't expect to be able to install Debian packages on
Cygwin anyway, did you?).
HTH,
