 # Administrative scripts
 Scripts for carrying out administrative tasks, mostly in Windows
 
+## AppX
+
+Deals with Microsoft Store app packages.
+
+1. `Inventory AppX Packages.ps1`: The `Get-AppxPackage` cmdlet in PowerShell can find all installed Microsoft Store apps, but it does not do a good job of discovering their display names. At best, it can show the technical package name. This script lists all AppX packages installed for the current user account, along with their display names. It accepts a `-Verbose` switch and its output can be piped to `Format-Table` or `Format-List`. I believe it can be expanded to work machine-wide.
+2. `(Specialized) Remove these appx packages.ps1`: This one is mostly for me, but others can find educational value in it. This script uninstalls a number of Microsoft Store apps for all users, without deleting their provisioned packages. I believe it can only run on Windows 10 version 1809 or later.

 ## Download
 
 1. `Download-Channl9VideosFromRSS.ps1` helps download entire Channel 9 sets of videos. It accepts one RSS URL for the video set and one download location.
