Winrt Storage For Default Photo App!?

Win10 Pro 64 (original install not an upgrade) photo app taken over by WinRT Storage API. Tried powershell listed here: https://answers.microsoft.com/en-us...-default/20a4da8a-f240-448b-9bb9-1b063d5fada8 and reg fix listed here https://www.techradar.com/how-to/how-to-restore-and-use-windows-photo-viewer-in-windows-10 , neither restored the photo viewer app as a choice. Help appreciated!

 

Here are registry entries on the same PC for a different user where the photo app works:

 

This PowerShell script resolved the problem:
Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
