In Windows 7 and 8.1, we had the following solution: Start Emacs
with runemacs.exe, pin it, close it, bring up the Properties for the
pinned icon, and change the target from emacs.exe to runemacs.exe.
That works as one would hope: either starting an instance of Emacs
or activating any existing instance.|
My habit for starting Emacs or activating an existing instance is to
use Windows-digit or (equivalently) clicking the pinned taskbar
icon. With Windows 10, it does not work. When I start Emacs with
the taskbar icon, it adds a new icon to the taskbar for the running
instance. If I use the pinned icon again, it starts yet another
instance. Windows-digit becomes useless because I don't know the
digit corresponding to the running instance of Emacs.
Could someone please point me to a solution for Windows 10? (If
there is not one, I guess I will resort to AHC.)
