Repair Windows 10 Start menu apps

Bring up the ‘Start’ menu by Right clicking on the ‘Windows Start Button’.

Click on ‘Windows PowerShell (Admin)’.

You will get a prompt asking ‘Do you want to allow this app to make changes to your device?’, Click ‘Yes’.

Next copy and paste the following text into the PowerShell window.

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

When the script is done running, close the PowerShell window by typing exit and press Enter.

Restart your computer.
