In this article, you will learn about “Application User Model ID: How to find the AUMID of an installed UWP App”. 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. Please see How to add WhatsApp UWP on Windows 11, Unable to uninstall AppX? How to uninstall builtin programs using PowerShell in Windows 10, and How to get Windows PC specific Model information.

How to find the AUMID of an installed UWP App

AUMID stands for “Application User Model ID.” It is a unique identifier assigned to a Windows application for use in the Start menu and taskbar. The AUMID is used by the operating system to distinguish between different applications and their instances.

Keep in mind that AUMID is subject to change with updates or changes to the application, so it’s a good practice to retrieve it dynamically rather than hardcoding it in your applications or scripts

Example one: Via the GUI (Windows Explorer)

Search for run dialog box and type the following to open the Application Explorer: shell:Appsfolder

This will open the following application explorer window.

Select details on the right hand pane

Access the View menu ALT+V, and 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
