How to maximize Emacs on Windows at startup?

Question

This is driving me crazy: I simply want Emacs to maximize to whatever screen resolution I have at startup. Ideally I like a cross-platform (Windows & Linux) solution tha

Answer 1

If you really want to run Emacs full screen without window chrome (title bar and max/min/close button), then try the mode below. This worked for me with Emacs 23.3.1 on XP SP3.

Answer 2

The following snippet from emacswiki worked fine from me: (add to your startup config file)

(defun jbr-init ()
"Called from term-setup-hook after the default
terminal setup is
done or directly from startup if term-setup-hook not
used.  The value
0xF030 is the command for maximizing a window."
  (interactive)
  (w32-send-sys-command #xf030)
  (ecb-redraw-layout)
  (calendar)
  )
(setq term-setup-hook 'jbr-init)
(setq window-setup-hook 'jbr-init)

Answer 3

This works reliably on Emacs 24.5.1 (i686-pc-mingw32):

(add-to-list 'initial-frame-alist '(fullscreen . maximized))
