I do not insist that the desktop icon should invoke emacsclientw
instead of runemacs.

On Windows, I suppose user launches App by choosing icon from Start
Menu.  After a while, spending minutes outside of the App, user wants
to switch back to the App.  The easiest way is choosing the same icon
from Start Menu again (without worrying if App is already running).
This works in Emacs on Mac.

Q: How do I launch and switch to Emacs by choosing the same icon in
   Start Menu?

The paragraph answers the question and shows recipe.  Since Q and A
about Windows, I thought it is good to have in FAQ.

> emacsclientw.exe "" --alternate-editor runemacs.exe

It took me a while to find out solution (that is just giving empty
argument).  If I am the one who had such a question, this is not
frequent, and I agree this should go to nowhere.
