I had some issues on my laptop so I did a restore to a restore point that I created earlier and everything went back to normal but a new problem developed. Now, when I try to open any modern app, it tells me "This app can't open" even store is not opening. I have done some search online and this code below seems to fix it Code: Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"} But when I run the command in PowerShell as instructed, I get this error Code: Add-AppxPackage : Deployment failed with HRESULT: 0x80073D02, The package could not be installed because resources itmodifies are currently in use. error 0x80004004: Unable to install because the following apps need to be closed Microsoft.Windows.Cortana_cw5n1h2txyewy!CortanaUI. NOTE: For additional information, look for [ActivityId] 734127fe-0ba0-0001-79a9-4173a00bd101 in the Event Log or use the command line Get-AppxLog -ActivityID 734127fe-0ba0-0001-79a9-4173a00bd101 At line:1 char:38 + ... | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.I ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (C:\Windows\Syst...ppXManifest.xml:String) [Add-AppxPackage], Exception + FullyQualifiedErrorId : DeploymentError,Microsoft.Windows.Appx.PackageManager.Commands.AddAppxPackageCommand Does anyone know what's wrong? or any other way to get the modern apps working again.
