The Application User Model ID (AUMID) is the identifier Windows uses to recognise a UWP app — and you’ll need it any time you want to launch one programmatically, pin it to the Start menu via Intune, target it in AppLocker, or surface a toast notification from the right “owner” application. The challenge is that the AUMID is rarely visible in the UI, varies between OEM-installed apps and re-published store apps, and can change after an upgrade. This post documents the three reliable ways I retrieve AUMIDs in production, plus how to use them in Intune assignments.
The AUMID is an ID which is assigned to each application installed on a device. It is used e.g. in the Kiosk multi app mode to select apps. Which possibilities exist to get this AUMID I want to explain you in this blog.
Possibility 1
Press WIN + R to open a Run dialog. Type in the following command and click OK:
shell:Appsfolder
A folder opens in which all applications are located

Press F10 and click View -> Choose details

- Select AppUserModelId and click OK

- Change the view to Details

Here we are. Here you can see the AUMID

Possibility 2
Open a Powershell and enter the following command:
get-StartApps

Possibility 3
Open the Registry Editor. Press WIN + R and type in regedit and click OK

Navigate to HKEY_CURRENT_USER\Software\Classes\ActivatableClasses\Package

Also here we can see all the AUMID.
Where AUMIDs actually matter in production
Knowing how to grab an AUMID is one thing; knowing where it shows up in real Intune work is what makes it worth memorizing.
- Toast notifications and ownership branding: custom toasts must reference an existing AUMID so Action Center attributes the message correctly.
- AppLocker and WDAC targeting: packaged-app rules match against the publisher and package family inside the AUMID, not the executable path.
- Pinned Start menu layouts via Intune: Start layout XML and the JSON pinning policy expect exact AUMIDs; one typo and the tile silently disappears.
- Per-user install tracking: AUMIDs correlate launches and crash telemetry back to the provisioned user, which matters on Cloud PC and shared devices.
- Upgrades and recovery: AUMIDs can change after feature updates or store re-provisioning, so always re-export them from a freshly imaged reference device before pushing policy.
