Re: [h-e-w] Windows 10 Taskbar Behavior

[Rob Davenport]

Interesting.  I ran my earlier test on this Windows 7 laptop and when I pinned 
Emacs, the shortcut did *not* have any App ID.   I don't have a Windows 8 
machine (my other laptop is now Windows 10), as I would like to test it there.  
But you're saying it works correctly in Windows 8.1.   Does it work for you in 
Windows 7?   If so, then there's something different about my Windows 7 machine 
causing it to not set the app id when pinning.  And apparently it only works in 
Windows 8.1, not 7 or 10.  Odd.

Either way, I think we have two ways to set the App ID in the shortcut 
(win7appid tool and the Details tab after applying that registry change - and I 
updated emacswiki.org with that tip as well [1]).

p.s. Every time this week I go to emacswiki.org it comes up in a non-English 
mode - it's been in Russian and Swedish for me.  Anyone else seen that?  I 
tried clearing cookies and cache.  Weird.

I think it is a bug in Windows 10.  Using the app ID program after I pin Emacs 
to the taskbar in Windows 8.1, the app ID associated with the shortcut is 
already "GNU.Emacs".  However, in Windows 10, the program reports that there is 
no app ID associated with the shortcut.  So setting the ID (as it should have 
been set on pinning the program) fixes the problem.  (I also observed that the 
app ID is not case sensitive.)
