As fun as it is to flip through apps on the Windows 8 Start screen, you’ll eventually have to use the traditional desktop to run popular applications such as Microsoft Word. However, transitioning between the desktop and Start screen can become tiresome. That’s why you’ll want to pin your favorite apps to the Start screen. Thankfully, it’s simple: just right-click on any app in the desktop, and at the top of the dialog (just below Open) you can click "Pin to Start."
You can also organize your pinned apps into groups. To do so, drag their tiles into an empty space on the Start screen, then zoom out by either pinching your figures together on the screen (if your laptop has a touch screen) or click on the Zoom button at the bottom right corner of the display. Right-click on the group. A menu bar will appear at the bottom, with an option for Name Group. Click on this icon and then give the group a name.
