If you got Windows 8 / 8.1 you will recognise this screen.

 

It can be difficult to find the app you need from the Windows 8 Start screen, because tiles take up so much of the screen. There is, however, a way to turn the Start screen into a useful app launcher. On the desktop right-click the taskbar and select 'Properties', then click the 'Navigation' tab. In the Start screen section, tick the box next to 'Show the apps view automatically when I go to Start'. From now on, when you go to the Start screen you'll see a list of all your apps rather than those big tiles.
