On Windows, Emacs by default uses a Lisp implementation of (the
most relevant parts of) ls, since Windows doesn't come with ls. Most
likely, Emacs's `ls-lisp' and your ls binary simply map Windows's
permissions to Unix-like permissions differently.

If that ls binary is on your PATH, you may be able to have Emacs use it
rather than `ls-lisp':

(with-eval-after-load 'ls-lisp
  (setq ls-lisp-use-insert-directory-program t))

That's what I do on Windows, using ls from Cygwin. There are a potential
issues from mixing a native Windows Emacs binary with Cygwin binaries,
but it's worked well enough for me.

There's also a Cygwin build of Emacs that uses a native Windows GUI.
I've been meaning to try it and that may be an option for you too.
