We don't know what we are looking for; only the end user does.  Even
Windows allows to rename executable files, so there's nothing magic in
the name gswin64c.exe, the actual program can be called anything and
can have any valid executable extension.  Please leave the user the
freedom of starting Ghostscript via a batch file, if they so wish.
