I wrote this article simply because I needed to get the AUMID of an Application needed for kiosk mode setup. Follow the steps discussed below to achieve this.
Example one: Via the GUI (Windows Explorer). Search for run dialog box and type the following to open the Application Explorer
– shell:Appsfolder
How to find the AUMID of an installed UWP App

This will open the following application explorer window.

Select details on the right hand pane

Access the View menu ALT+V, choose Choose Details
– or use the f10 key to display the view and click choose details

Check the box next to AppUserModelId and press OK

This will display the result below

Note: When you close the Application Explorer, this option is unchecked by default.
Example 2: Via PowerShell to get the AUMID of an Application.
run the PowerShell script as shown below.
$installedapps = get-AppxPackage
$aumidList = @()
foreach ($app in $installedapps)
{
foreach ($id in (Get-AppxPackageManifest $app).package.applications.application.id)
{
$aumidList += $app.packagefamilyname + "!" + $id
}
}
$aumidList
Also, you can run just the code below to get a list of all installed apps via PowerShell
get-AppxPackage
