Cheers, you're a lifesaver. Those PowerShell commands solved it for me as well. I however did NOT have to delete the old cert. Take care, Giovanni

Hi Benzini00 I managed to get it working without errors: Machine startup script: New-Item -ItemType Directory -Force -Path C:\Support Get-ChildItem "C:\Program Files\WindowsApps" | Where-Object {$_.name -like "Microsoft.UI.Xaml*"} | Select Name | Export-CSV -Path C:\Support\MicrosoftApps.csv -NoTypeInformation User Logon script: $items = Import-CSV C:\Support\MicrosoftApps.csv foreach ($item in $items) { $foldername = $item.Name Write-Host $item.Name Add-AppxPackage -DisableDevelopmentMode -Register "C:\Program Files\WindowsApps\$foldername\AppxManifest.xml" } What error are you getting?
