Windows 8 looks quite different from Windows 7. This is because it is designed to also work with touchscreen computers and tablets.
-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 the bottom of the screen and click All Apps.
-In Windows 8 we can use apps and programs. Apps open full screen in Metro; programs open on the Desktop just as they did in Windows 7.
-Additional apps can be downloaded from the Windows Store.
