When you log in to Windows 8, the first screen you see is the new ‘Start Screen’, also known as ‘Metro’. It still has the familiar ‘Desktop’ as well but we’ll come to that in a minute. Instead of Icons, the new Start screen has ‘Tiles’. You click these to open your ‘Apps’ (short for Applications). If you can’t find a particular tile, do a right mouse click in the space at there

Windows 8 has been engineered with a full set of gestures that work system wide: swipe from the right to access the Charms menu, swipe from the left to switch between running programs, swipe from the top or bottom for access to the App bar in Metro apps.

In addition, it supports a full range of multi-touch gestures for scrolling, panning, rotating, and so on.

By contrast, Windows 7 has a limited set of touch gestures, and touch support is essentially a replacement for mouse actions. In addition, the quality of the touch experience is greatly dependent on third-party hardware and drivers, which are of variable quality.

Touch targets in Windows 8 are optimized for the lower precision of a finger (roughly 16 pixels) compared to a mouse pointer, which can point to a single pixel. This optimization extends to desktop features like Windows Explorer, which has been redesigned so that it works very well with touch. If you try Windows Explorer on a touch-capable device in Windows 7 and Windows 8, you can literally feel the difference.

The system requirements for Windows 8 specify that a compatible device must support a minimum of five simultaneous touch points. Some Windows 7 devices support only a single touch point, making gestures like two-finger scroll and rotate impossible.
