My crystal ball says you are both looking at the wrong measure of
memory.  Emacs 24 and before _reserved_ 1.6GB of memory, but didn't
commit more than it actually needed.  So it was never a memory hog.

Emacs 25 changed the way it allocates memory on Windows, so it no
longer needs to reserve anything.
