Windows 8 Find your applications

The Win+X menu is useful, but no substitute for the old Start menu as it doesn't provide access to your applications. To find this, hold down the Windows key and press Q or either right-click an empty part of the Start screen or swipe your finger up from the bottom of the screen and select 'All Apps' to reveal a scrolling list of all your installed applications. Browse the various tiles to find what you need and click the relevant app to launch it.
