This video is showing you how to hide or show tiles on your homepage of your HP TouchSmart. You can look at all your available tiles on your homepage by tapping on the "personalize" button. The tiles that are dimmed means that it is hidden, and the tiles that are bright mean that it is showing. To hide a tile, just tap on it and it will go dim. To make a hidden tile shown, just touch it and it will turn bright. When you are finished choosing which tiles to show and which tiles to hide, click "ok". Now your changes have been made.
