It works in Windows 11 too. I just tested this in 
Win11_22H2_EnglishInternational_x64v2.iso Home edition, upgraded.

"(push '(fullscreen . maximized) default-frame-alist)" is added to 
.emacs.d/early-init.el it expanded the buffer equally quickly like when 
this was added to a .emacs file (with 100 lines):

(add-hook 'emacs-startup-hook 'toggle-frame-maximized)

(setq frame-resize-pixelwise t)
(set-frame-position nil 0 0)
(set-frame-size nil (display-pixel-width) (display-pixel-height) t)


For GNU/Linux adding this to .emacs (same file size as for the Windows 
11 experiment) caused a delay:

(add-hook 'emacs-startup-hook 'toggle-frame-maximized)


So for Windows, there are two methods that can be used, but for 
GNU/Linux only one solution works (adding "(push '(fullscreen . 
maximized) default-frame-alist)" to .emacs.d/early-init.el)


With this said, the OS independent solution is to add "(push 
'(fullscreen . maximized) default-frame-alist)" to 
.emacs.d/early-init.el which can be documented in a new page, 
https://www.gnu.org/software/emacs/manual/html_node/efaq/Fullscreen-mode.htm

Eli said: "

"Fullscreen" is widely accepted terminology for what is discussed
there.  Moreover, typing "i maximized RET" and "i fullscreen RET" in
both the ELisp and the Emacs user manuals brings you to the same text,
so we already have the two equivalent terms covered, and renaming the
node is not necessary IMO."
