Not quite.  Judging from your cygcheck output, you use startxwin.bat.

Do you have a small testcase that would allow others to reproduce this?
Perhaps a (small) sample .zip file?

They most likely are unrelated.

I'd suspect the unzip issue has to do with the path length to the file.
You can try confirming it by creating a file in a deeply nested directory,
putting that one file in a .zip, and then trying to unzip it into some
place even deeper in the directory hierarchy.  Can't help you with the
emacs issue, as I don't use emacs.

This (and the existence of CYGWIN_ROOT in your environment) is an artifact
of using startxwin.bat.  Unless you have a default directory for the
Cygwin root, you can't use that file OOTB -- you'll have to edit it and
replace "\cygwin" with the value of your Cygwin root (in your case,
"d:\ProgramFiles\Cygwin".

Hope this helps,
