This is a duplicate of bug#65138, for which we don't yet have a
solution.  Patches welcome.

This is not a bug: you need to clear the font cache to get Emacs to
react to newly-installed fonts without restarting Emacs.  Like this:

  M-: (clear-font-cache) RET

> Here is a sample setting to display emojis:
>   (set-fontset-font nil '(#x1f000 . #x1faff) "Segoe UI Emoji")

Segoe UI Emoji is not a free font, so we cannot advertise it in Emacs.
You could tell Emacs about any fonts you have that support Emoji by
using the function w32-find-non-USB-fonts, see its doc string for
details.

In addition, Emacs 29 comes pre-configured to use the Noto Emoji font
on MS-Windows for showing Emoji, but you need to install that font
first.
