Which parts in your code are specific to Windows?

All of it, see the attached file in this email.

??? These variables and functions work in any GUI environment that
Emacs supports, including GNU/Linux, any platform that runs X, macOS,
etc.  So I don't quite understand why you say this is
Windows-specific.  What did I miss?

It can only be used to "avoid the slightly distracting visual effect of Emacs starting with its default frame size and then growing to fullscreen" in Windows. But NOT in GNU/Linux.

You can use it in GNU/Linux, but it is totally useless to avoid the slightly distracting visual effect, so it serves not point. Therefore, it's Windows-specific.

Can someone else please try to explain this?
