With Windows 8.1 out of the way, Microsoft has now begun work on Windows 8.2. According to sources close to the development Windows 8.2, dubbed Threshold, Microsoft will bring Windows, Windows Phone and Xbox One closer together -- to the threshold, if you will, of being a fully unified OS. Furthermore, again according to insider sources, Windows 8.2 will introduce a "traditional desktop" SKU that is optimized for mouse-and-keyboard Desktop users and resurrects the original Start menu.
