When launching an Avalonia application via a Windows Service (configured to start automatically on boot), the system tray icon fails to initialize. However, manually restarting the service after Windows login successfully loads the tray icon.

The issue occurs because the service runs under the SYSTEM account. Windows cannot send the "TaskbarCreated" message to windows owned by the SYSTEM context. This requires explicitly allowing message reception using ChangeWindowMessageFilter.
