If you’re having problems with metro/store apps in Windows 10, such as apps not loading or the Windows Store opening and closing immediately and have tried the various (incomplete) guides found across the internet but haven’t been able to get your Windows Store apps to actually reinstall, then these are the instructions for you.

Get-ChildItem 'C:\Program Files\WindowsApps\' -recurse | Foreach { if ($_.Name -like "App*Manif
est.xml") { "$($_.Directory)\$($_.Name)" } } | foreach { Add-AppxPackage -DisableDevelopmentMode -Register $_ }

What these instructions do is enumerate all the applications available (installed or otherwise) living under C:\Program Files\WindowsApps\ and uses their application manifest file (typically AppxManifest.xml) to reinstall the application.

Unlike other instructions, this does not require that the application be currently installed.

Make sure to run this in an elevated PowerShell prompt, though!
