The most striking, in-your-face, and noticeable part of Windows 8 is its new Metro user interface, and in particular, its Start screen. The Start screen is a replacement for the Start menu that has been a feature of Windows for the last 16 years. The Start screen is touch-friendly, fullscreen, and filled with live, active tiles. It couldn't look much more different from the Start menu. Microsoft is well aware of this, and has begun tweaking the Start screen in response to user feedback.
