I have windows 10 Home
Somehow I accidentally changed something so that instead of the display on my desktop showing all my shortcuts it shows my start menu icons and the start menu icon is gone from the left hand bottom of the screen I still get the desktop image though.
Also when you right click on a empty portion of the task bar instead of the usual stuff you get a box saying
(Check marked) show all app icons
Show all notification Icons (not checked)
Show Touch Button Keyboard (not checked)
