In some XBOX apps you get the error 0x406 and you don’t know what to do?
Apps and Games like ReCore freeze on startup?
Here is the solution:

Start the Powershell as admin and enter this (i skipped both lines and just did the third command):
Get-AppxPackage *windowsstore* | Remove-AppxPackage
Get-AppxPackage *xboxapp* | Remove-AppxPackage

(now Restart your computer and go again into powershell and type)

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