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

[Rob Davenport]

Now on my Windows 10 laptop, I'm not seeing David's original problem.  I can pin Emacs after running it from runemacs.exe and run multiple instances and they are grouped on the taskbar as desired.  i checked and the shortcut does not have an AppID, but things are working as desired. 

I added the AppID to the shortcut in my Start Menu folder, started Emacs using it, pinned it to the taskbar, and the shortcut *does* have the "GNU.Emacs" AppID and things work as desired.  

So now I'm not sure what's going on.  I've gotten it to work on Win7, Win8, and Win10.  And maybe on this Win10 laptop things have gotten messed up.  I may have to create plain VMs without Emacs every having been installed/run and then test things.   But for now, it seems it *can* be made to work on all three OS's, maybe having to set the AppID in a shortcut.

The start menu is involved because I noticed when monitoring file/registry activity during the act of pinning Emacs, I saw that windows was looking at the Emacs.lnk file that happened to be in my Start Menu.   That shortcut didn't have an AppID.  When I put GNU.Emacs in for the AppID, *then* pinning correctly created a pinned shortcut with the AppID.

I assume when pinning, Windows looks for various clues as to what AppID to give the shortcut.  It also looks in the registry for things too.  I assume it wasn't able to determine what AppID to use for me until I set it in the shortcut in my Start Menu.

Does the shortcut icon on your desktop have the AppID set?  How did you create that shortcut?
(I just tried dragging runemacs.exe with a right-click and choosing "Create Shortcut here" and that one did not have an AppID.)

I'm not sure how the one in my start menu got the app id.  I suspected I must have run addpm at some time and that added the appid, but it doesn't have code to do that.  (And running addpm used to be necessary or at least very useful - moreso than recently, so I know I've run it occasionally to set registry entries and environment variables, but I typically don't.  But I remembered it when see the Start Menu being examined during pinning and thought that using addpm might be a difference in what I do that could be causing different behavior.)

Sorry, I got lost here somewhere.  What does the Start Menu have to do with this issue?

I start Emacs from a desktop icon that invokes runemacs.exe.

I never use addpm.  Why do you use it?
