Do you really need that?  The Windows Explorer can unzip files just
fine, and a browser or Emacs itself can be used to fetch files.

It's best not to go there at all.  Changing PATH from within Emacs is
asking for trouble, because the system outside Emacs doesn't know
about that, and changing PATH system-wide requires going to system
properties and making changes there (which sometimes might mean
privileges normal users don't have).  Try avoiding that, is my advice.
