[Python] How to get the app name from `app_user_model_id` in Python using winsdk / WinRT?

I'm using the winsdk Python package (WinRT bindings) to access media sessions via GlobalSystemMediaTransportControlsSessionManager.

I can successfully get the list of active sessions and their source_app_user_model_id using:

from winsdk.windows.media.control import GlobalSystemMediaTransportControlsSessionManager as MediaManager

manager = await MediaManager.request_async()
for session in manager.get_sessions():
print(session.source_app_user_model_id)


For example, I get values like:

Chrome.AI6Y5TE6AH3DDYXV66D2XOWVLA
308046B0AF4A39CB


(The second is Firefox id lol)


I want to resolve these IDs to user-friendly app names (like "Google Chrome" or "Firefox").

In C++/WinRT, I found this solution using AppInfo::GetFromAppUserModelId:

from winsdk.windows.applicationmodel import AppInfo

def get_display_name(app_id):
return AppInfo.get_from_app_user_model_id(app_id)


But it throws:

OSError: [WinError -2147023728] Element not found


I assume this happens for non-UWP apps.


I also tried using the Windows.Management.Deployment.PackageManager to enumerate installed packages and get their display names:

from winsdk.windows.management.deployment import PackageManager
pm = PackageManager()
for package in pm.find_packages_for_user(""):
print(package.display_name)


However, this only returns a list of system or default apps available for new user accounts (like Microsoft Edge, Photos, etc.). It does not include apps like Chrome or Firefox.

How can I get the application display name from source_app_user_model_id using Python and winsdk / WinRT? Is there any fallback method for non-UWP apps (e.g. Firefox, Chrome)?
