The System Tray icons are not opening. Clicking Start, Cortana, Network, Battery, and Action Center icons , nothing happens.
It’s a known issue in Build 10130 that sometimes causes the icons in the system tray to not launch the flyout that they are supposed to. Sometimes if you try for several times it starts working automatically.
If you still face the problem then try the following:
From the Start menu, search for task manager.
Select Task Manager from the results.
Tap or click the Processes tab.
Under Background processes, select System Settings Broker, and then tap or click End Task.
