Yuck!  I _hate_ this unportable stuff!

You can't, not without significant changes to Dired.  It currently
assumes that the association in dired-compress-file-suffixes is a file
name of a program, not a shell command.

Does it help to copy gzip.exe to gunzip.exe?

If that doesn't work (it depends on how your gzip.exe was compiled),
then perhaps crafting a gunzip.bat batch file that invokes "gzip -d %*"
will work.
