Yes, Emacs probably uses that binary. You should see a message to
that effect in *Messages*. How does it know? it looks along your PATH
to find the executable it needs.

You should be able to find a Windows port of gzip on the GnuWin32
site:
http://gnuwin32.sourceforge.net/packages/gzip.htm
AFAIK, that's what I'm using; never bothered to port a newer version
because that one does a good-enough job for my needs. (But of someone
points out why newer versions are so much better, I might be tempted
to provide their binaries.)
I'm quite sure there's a 64-bit port of gzip available from the MSYS2
site, but you'll have to find it yourself, or maybe someone else here
could post a URL.
