If you need to download an MSIX/APPX package from the Microsoft Store, you don’t technically have any alternative rather than the actual Store. But I’ve stumbled upon a PowerShell script designed by Mattias which is easy to use and so far it works great.
First, navigate to the GitHub repository and download the Download-AppxFromStore.ps1 script. Once you downloaded the script, it’s time to search for the desired package from the store.
To do this, go to the start page of the Microsoft Store in your desired browser and search for the desired application. In my case, I went ahead and searched for Python 3.8.
As you can see, it is without the #activetab=pivot:overviewtab
powershell.exe -executionpolicy bypass -file “D:\Download-AppxFromStore.ps1” -StoreURL https://www.microsoft.com/en-us/p/python-38/9mssztt1n39l
Replace “D:\Download-AppxFromStore.ps1” with the actual location where you stored the ps1 script and replace the store url with the one desired.
