Ever work on windows 8 or 8.1 and find the modern apps won’t start?

Yesterday I tried opening my modern apps and all I’d get is a black screen then bomb back to the start screen.

Piss me off, I wanted to use the music app to drown out the background noise around the office.  So I dug into it and found this handy PowerShell script.

((Get-ChildItem “HKLM:SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore\InboxApplications”) | Get-ItemProperty).Path | Add-AppxPackage -Register -DisableDevelopmentMode

I ran that and I was back in business. Or back into Xbox Music. I found this script on this article:
