Originally developed by Kiran Murmu and later maintained through various GitHub projects, WSAppBak allows users to extract the contents of the protected C:\Program Files\WindowsApps directory and convert them back into installable packages. This is particularly useful for:

Sideloading: Creating .appx installers to use on other Windows machines without an internet connection.
Development: Analyzing the manifest files and structure of existing Store applications. How WSAppBak Works

Locate the App: Find the specific folder of the app you wish to backup (e.g., Microsoft.WindowsCalculator_...).
Run the Script: Provide the app path and the desired output path to the WSAppBak script.
