This PowerShell workshop will show you the steps to re-register a specific app in Windows 10 to fix all issues with it, without reinstalling app from Store.

If you want to reset apps in Windows 10, click here.

Many times, it happens that a particular app doesn’t responds and we need to fix it. Users having this type of issues have only one thing in mind to fix this problem, and that is to reinstall the app. Now for some cases, reinstall helps and fixes user issues with the app. But there exists some others scenarios as well, in which user continue to facing problems with the app even after re-installation. For such cases, you should re-register the app particularly to sort the hitch.

We have already seen the steps to re-register all Modern Apps at once in Windows 8.1. While in Windows 10, the cmdlets are quite different due to existence of Universal Apps. Generally, it is recommended to reinstall all apps at once, which is not relevant to follow if all other apps are working fine and you’ve problems with a single app. Here, in this article, we’re going you to share the cmdlets embedded in a step-by-step approach, so that you can easily re-register an app that is not working for you.

How To Re-register A Specific App In Windows 10

1. In the search box on taskbar, type windows powershell and right click on Windows PowerShell from results, select Run as administrator.

3. Previous step cmdlet will populate a list of all apps installed on your Windows 10 along with their technical details. For each app, there is a PackageFullName, which you’ve to note down for the app you wish to re-register. It will be required in successive step here.

In this example, we’re showing the procedure of re-registering Xbox app. Hence for that, the package name in our case is Microsoft.XboxApp_7.7.29027.0_x86__8wekyb3d8bbwe.

4. Now we’re in the final step, where we will run the re-install cmdlet. Here is what you have to type and press Enter key:

Add-AppxPackage -register "C:\Program Files\WindowsApps\<PackageFullName>\appxmanifest.xml" -DisableDevelopmentMode

*Substitute, C: with your system root drive and <PackageFullName> with the app’s full package name which we noted down in previous step.

For example, to re-register Xbox app installed on C: drive, I’ll use this cmdlet:

Add-AppxPackage -register "C:\Program Files\WindowsApps\Microsoft.XboxApp_7.7.29027.0_x86__8wekyb3d8bbwe\appxmanifest.xml" -DisableDevelopmentMode

  • Not only it didnt work but it f***** up the Windows Store too which was the only one working. Before I tried this, the apps would start and then close by themselves, now they dont even start

  • Kapil Arya

    ^^ You may try creating new user account and all apps will be back on it.

  • Thank you very much for this article. Worked first time for me re-register the Calculator app.

  • Thank you! This fixed my Twinui class not registered error I was getting when I tried to open pictures after upgrating to Windows 10 Anniversary Edition.
    I used the following command to fix my system:
    Add-AppxPackage -Register ‘C:\Program Files\WindowsApps\Microsoft.Windows.Photos_16.722.10060.0_x64__8wekyb3d8bbwe\AppxManifest.xml’ -DisableDevelopmentMode

  • Kapil Arya

    ^^ Glad it helped 😎

  • I tried many unsuccessful approaches to solving a “class not registered” error with mp3 and WAV files which occured after a recent Windows 10 upgrade. In the end I used the cmdlet to re-register all installed apps at once. As a result MP3 and WAV files now open in Groove. Previously they opened in Windows Media. Why has this default changed?

  • Kapil Arya

    ^^ Since you re-registered all apps, hence default association got a reset :)

  • Kapil, Step 5 was all that I needed – you’re a star. you’ve saved me a lot of work and heartache. Many Thanks

  • Kapil Arya

    ^^ Awesome 😎

  • It would be nice if the example provided for how to repair calculator app used the calculator app instead of the xbox app.
    Also, get-appxpackage returns only four apps for me. None of these has calculator in the name. Yet, when I type calculator in the search, there’s the icon. When you click it, nothing happens. When I type “calc”, I get a different icon. Clicking that one gives the error “You’ll need a new app to open this calculator.”
    To make a long story short, how do I re-register an app which Get-appxpackage doesn’t list?

  • I not only tried to re register photo app which never worked individually, but tried to re register all apps and now none of the apps work. Help!
