** "Pinning" Emacs to the taskbar doesn't work on Windows 10
"Doesn't work" here means that if you invoke Emacs by clicking on the
pinned icon, a separate button appears on the taskbar, instead of the
expected effect of the icon you clicked on being converted to that
button.
First, be sure to edit the Properties of the pinned icon to invoke
runemacs.exe, not emacs.exe. (The latter will cause an extra cmd
window to appear when you invoke Emacs from the pinned icon.)
But the real cause of the problem is the fact that the pinned icon
(which is really a shortcut in a special directory) lacks a unique
application-defined Application User Model ID (AppUserModelID) that
identifies the current process to the taskbar. This identifier allows
an application to group its associated processes and windows under a
single taskbar button. Emacs on Windows specifies a unique
AppUserModelID when it starts, but Windows 10, unlike previous
versions of MS-Windows, does not propagate that ID to the pinned icon.
To work around this, use some utility, such as 'win7appid', to set the
AppUserModelID of the pinned icon to the string "Gnu.Emacs". The
shortcut files corresponding to icons you pinned are stored by Windows
in the following subdirectory of your user's directory (by default
C:\Users\<UserName>\):
AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar
Look for the file 'emacs.lnk' there.
