Installing Microsoft Store Apps

Getting Started

We’re going to install “HEVC Video Extensions from Device Manufacturer” (yes, that’s the name of it) and “HEIF Image Extensions”. Both these apps are free and useful to add to a Windows deployment as they will allow newer image and video formats to be viewed.

Obtain the AppX Packages

Google both the “HEVC Video Extensions from Device Manufacturer” and “HEIF Image Extensions” and copy the URLs from the web version of the Microsoft Store.

We’re going to use a third party site to download the required files, go to and enter the URL for one of the apps.

Download the .appx and .blockmap files for the app. There is no need to download all versions or the .eappx files, just the .appx and the .blockmap files.

Repeat the process for the other app.

Installing An AppX

Run this Powershell command to install the app for all users:

Add-ProvisionedAppxPackage -Online -PackagePath "$PathToFiles\AppX-ToAdd\Name-Of-The-App.Appx" -SkipLicense

The app will now be installed for all users.

Final Thoughts

The -SkipLicense option is used because these are free apps with no license xml file. I presume (but haven’t tested yet) that for paid apps if you can obtain the appx file and extract the license file from an existing installation and then run the Add-ProvisionedAppxPackage command and specify the license file.

For MDT users who want to deploy AppX’s as part of a Task Sequence, I’d recommend putting this near the end of a Task Sequence and having the App files in a folder on the MDT server like any other application.
