My Windows 10 modern UI will not open

In Windows 10, My modern UI opens but nothing will open when I click on the panels?

Have you tried restarting the computer? Also, make sure you have all the latest updates by going to settings - updates & security

(If the start menu is unresponsive, you can access settings through Action Center - click on the Notification icon in the systray, right next to the clock - bottom right hand corner. Then "all settings")
