I am developing app with windows 8 metro style. This app has some more feature if it running in desktop pc compared to Tablet. But my problem is how to detect app is running
@Mahantesh: If it's specifically between Desktop PC & Tablet (excluding laptop), then you can check the "battery properties" such as AC/Battery Supply, Battery remaining etc. which as far as I know are available only for computers running on battery power & certainly Desktop doesn't do that.
In simpler terms, the battery notification is not available for my Desktop PC whereas it's there for my laptop.
