Emacs can save and restore the frame geometry if you use the
desktop.el package to resume your sessions.  This is in the manual.

We have that as an optional feature, see above.

Emacs on MS-Windows emulates X resources by storing them in the
Registry.  This is also described in the user manual, which see.  So
you can have this feature even without desktop.el, if you want.

P.S.  One thing I learned about Emacs a long time ago is that for any
issue that might worry you, it is likely that someone already solved
it in Emacs.  So the first thing I do when U bump into such annoyances
is to search the manual and the built-in documentation for similar
features.  Usually, I find a solution that is ready to be used; I
stopped being amazed by that long time ago.
