How To Find Application User Model ID (AUMID) Of Installed App In Windows 11

The Application User Model ID (AUMID) is an identifier used by the Windows operating system to identify installed apps, particularly those that are UWP (Universal Windows Platform) apps. This ID is useful for developers, IT professionals, and advanced users who want to manage or automate tasks involving specific apps, such as configuring notifications, pinning apps to the Start menu, or creating custom scripts.

In this guide, we’ll show you several methods to find the AUMID of installed apps on Windows 11. Whether you’re a developer working with PowerShell scripts or just curious about how Windows manages apps, this guide will walk you through the process in easy-to-follow steps.

What is the AUMID in Windows 11?

AUMID stands for Application User Model ID, and it is a unique identifier assigned to each UWP app installed on your system. These IDs help Windows manage various functions of the app, such as launching, pinning to the taskbar, or controlling notifications. Knowing an app’s AUMID can be particularly useful for tasks like scripting automation or customizing the app’s behavior in Windows.

Why Do You Need the AUMID?

Here are a few scenarios where finding the AUMID is essential:

• Automating tasks using PowerShell: AUMID is required when automating app launches or customizing their behavior via PowerShell.
• Managing app notifications: AUMIDs are used when managing notifications for UWP apps.
• Customizing Windows layouts: When creating custom layouts or scripts, you may need AUMIDs to pin specific apps to the taskbar or Start menu.

Now, let’s explore the different methods to find the AUMID of installed apps in Windows 11.

Method 1: Use PowerShell to Find AUMID

The most straightforward way to find the AUMID of an installed app in Windows 11 is by using PowerShell. Follow the steps below:

Step 1: Open PowerShell

1. Press Win + X and choose Windows Terminal (Admin) to open PowerShell with administrator privileges.
2. Alternatively, you can search for PowerShell in the Start menu, right-click, and select Run as administrator.

Step 2: Run the PowerShell Command

Once PowerShell is open, run the following command to list all the installed apps and their associated AUMIDs:

powershellCopy codeGet-StartApps | Select-Object Name, AppID

This command will display a list of all installed UWP apps, showing their Name and AppID (which is the AUMID).

Step 3: Identify the App

Scroll through the list to find the app you’re looking for. The AppID column contains the AUMID of the app, while the Name column displays the name of the app.

For example, if you’re looking for the AUMID of the Calculator app, you’ll find something like this:

diffCopy codeName            AppID
----            -----
Calculator      Microsoft.WindowsCalculator_8wekyb3d8bbwe!App

In this case, the AUMID of the Calculator app is Microsoft.WindowsCalculator_8wekyb3d8bbwe!App.

Method 2: Find AUMID via Registry Editor

You can also find the AUMID of installed apps by searching the Windows Registry. This method is a bit more complex but can be useful for getting more detailed information about each app.

Step 1: Open the Registry Editor

1. Press Win + R to open the Run dialog box.
2. Type regedit and press Enter to launch the Registry Editor.
3. If prompted by User Account Control (UAC), click Yes to allow access.

Step 2: Navigate to the Appx Registry Key

In the Registry Editor, navigate to the following location:

mathematicaCopy codeHKEY_CURRENT_USER\Software\Classes\ActivatableClasses\Package

Here, you will see a list of installed apps, each represented by a folder with the app’s package name.

Step 3: Find the AUMID for Your App

• Look through the list of apps and find the one you’re looking for based on its package name.
• The AUMID is usually a combination of the package name followed by !App. For example, the Calculator app might have an entry like this:

Copy codeMicrosoft.WindowsCalculator_8wekyb3d8bbwe!App

Method 3: Use Shell Command to Find AUMID

You can also use the Shell command to directly find the AUMID of specific apps installed on your system.

Step 1: Open Command Prompt

1. Press Win + R to open the Run dialog.
2. Type cmd and press Enter to open the Command Prompt.

Step 2: Use the Shell Command

Once the Command Prompt is open, type the following command to list all UWP apps installed on your system:

cmdCopy codeexplorer shell:AppsFolder

This will open the AppsFolder, which contains all installed UWP apps.

Step 3: Find the AUMID

• In the AppsFolder, right-click on any app icon and select Create Shortcut.
• Windows will create a shortcut on your desktop.
• Right-click on the newly created shortcut and go to Properties.
• In the Target field, you will find the AUMID of the app.

For example, if you create a shortcut for the Weather app, you might see the following in the Target field:

Copy codeMicrosoft.BingWeather_8wekyb3d8bbwe!App

This string is the AUMID for the Weather app.

Method 4: Use the AppxPackage Command in PowerShell

Another method to find the AUMID involves using the AppxPackage command in PowerShell. This method gives detailed information about each UWP app installed on your system.

Step 1: Open PowerShell

As with the first method, open PowerShell with administrator privileges by pressing Win + X and selecting Windows Terminal (Admin).

Step 2: Run the Get-AppxPackage Command

To list all installed apps along with their package names, run the following command:

powershellCopy codeGet-AppxPackage | Select-Object Name, PackageFullName

This command will display a list of installed apps, their names, and package information. The PackageFullName is a detailed identifier that includes the AUMID.

Step 3: Find the AUMID

The PackageFullName will often contain the AUMID. For example, the entry for the Microsoft Store app may look something like this:

diffCopy codeName                                PackageFullName
----                                ---------------
Microsoft.WindowsStore               Microsoft.WindowsStore_8wekyb3d8bbwe!App

Here, Microsoft.WindowsStore_8wekyb3d8bbwe!App is the AUMID for the Microsoft Store.
