How to show Taskbar icons when on tablet mode
By default, Windows 10 hides your Taskbar icons when on Tablet mode.
You will need to unset or turn off the "Hide app icons on the taskbar in tablet mode" option on the settings menu.
To do this:
1) Click Start -> Settings -> System
2) On the left panel, select Tablet mode. You can also search "tablet mode" in the Windows search box
3) Turn off the "Hide app icons on the taskbar in tablet mode" by moving the bar to the left.
You should now see your taskbar icons when on tablet mode.
