I am trying this fix:

Add-AppxPackage -register "C:\Program Files\WindowsApps\Microsoft.WindowsCalculator_10.1601.49020.0_x64__8wekyb3d8bbwe\appxmanifest.xml" -DisableDevelopmentMode

But I get this error

Add-AppxPackage : Deployment failed with HRESULT: 0x80073CF6, Package could not be registered. (Exception from HRESULT: 0x80073CF6) NOTE: For additional information, look for [ActivityId] e90d0759-d78a-0003-b82e-42e98ad7d101 in the Event Log or use the command line Get-AppxLog -ActivityID e90d0759-d78a-0003-b82e-42e98ad7d101 At line:1 char:1 + Add-AppxPackage -register "C:\Program Files\WindowsApps\Microsoft.Win ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : WriteError: (C:\Program File...ppxmanifest.xml:String) [Add-AppxPackage], IOException + F

ullyQualifiedErrorId : DeploymentError,Microsoft.Windows.Appx.PackageManager.Commands.AddAppxPackageCommand

It looks like windows 10 default apps is quickly becoming a huge mess and that Microsoft never provided a tool to fix it easily. Is there any other options other than refreshing my install ?

Issue seems to be occuring after each cumulative update.

  • Doesn't happen to me, so what command have you ran, to uninstall these applications in the past?

See if this command-line helps..automatically registers the latest version.

Get-AppxPackage -allusers Microsoft.WindowsCalculator | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Note that the folder name for the current version (10586.420) would be:

C:\Program Files\WindowsApps\Microsoft.WindowsCalculator_10.1605.1582.0_x64__8wekyb3d8bbwe
  • I did this and have the same error. The store doesn't work as well. Same error when trying to register it. I have the same build version.

  • I ran DISM but this did not help
