I have just upgraded from Windows 8.1 to Windows 10. It worked fine for a week and now my Start Icon will not work.
I have tried this option with no success:

  1. Press Windows Key + R on your keyboard.
  2. Key in PowerShell and hit Enter.
  3. Right click on the PowerShell icon on the taskbar and select Run as Administrator.
  4. Now paste the following command in the Administrator: Windows PowerShell window and press Enter key:Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
  5. NOW for the important part ! Locate to : C:/Users/name/AppData/Local/ and delete the TileDataLayer folder.

    When I try this I get the following error when I run Powershell as administrator.
