Windows 8 Learn Ribbon and the Quick Access toolbar
Windows 8′s other big interface change is the addition of the Ribbon to Internet Explorer. The icon-driven UI replaces the text-menu interface of the old version. However, it only sometimes appears by default. To summon it, you need to use the new option tabs at the top of Explorer (Home, Share, View, etc.). You also an click the tack icon at the upper right or you can use the Ctrl + F1 hotkey.
When Ribbon is not active you will see the slimmer Quick Access toolbar. It has only a few fuctions by default, but users can add more. To do this, open the Ribbon, right-click on an icon, and then click “add to Quick Access toolbar.
