Why windows task bar custom task list doesn`t work without pin on windows 10?

The minimal working example with QML JumpList (same behaviour if using QWinJumpList in c++).

import QtQuick 2.3
import QtQuick.Window 2.2
import QtWinExtras 1.0

Window {
    visible: true

    JumpList {
        JumpListCategory {
            visible: true
            title: "Test"

            JumpListLink {
                title: "Test Link"
                executablePath: "http://google.com"
            }
        }
    }
}

After launch appliction you may press right mouse button on the application in windows task bar and look at something like:

custom menu in application task bar

If press to Test Link menu item the default browser with http://google.com url should be opened because of under the hood it uses shell execute. This work well in windows 7, 8, 8.1.

In windows 10 this doesn`t work while you do not pin application to task bar by hands. After this done the link is working.

Why this so and how it can be fixed?

UPDATE 1: This strange behaviour was tested with Qt 5.5, 5.5.1, 5.6 and master branch on Windows 10 - dev, first released home version, final home, pro. And results is same - not working. Also, for example, chrome uses custom list (the site section) and it works well without pinning.

UPDATE 2: Here is my qt bug QTBUG-49486 about this and related to it QTBUG-48751. But the problem is right now the Qt devs do not know how to fix this problem too.

Solution

  • It was fixed in windows 10 major update from 12.11.2015
