+.SYNOPSIS
+  Returns the package identities and display names of all installed packaged apps (AppX)
+.DESCRIPTION
+  Get-AppxPackage returns a list of all installed packaged apps, along with their "Name",
+  "PackageFullName", and "PackageFamilyName" properties. None of these are human-consumable. For
+  example, what is "58027.265370AB8DB33_fjemmk5ta3a5g"? This script reveals the display name of all
+  installed packaged apps.
+.NOTES
+  DEPRECATED
+
+  This script depends on Get-AppxPackage and its Appx module. As such, it won't work in PowerShell
+  6 and later.
+
+  Instead of this script, consider using WinGet.exe.
