Add New Apps from the Windows 8 Store App
Click Install, Buy, or Try button.
When you find a free app that you can’t live without, click the Install button. Paid apps let you click either Buy or Try (a limited trial run). If you choose to install, try, or buy an app, its tile appears on your Start screen as quickly as your Internet connection speed allows.
Newly downloaded apps appear in a group on the Start screen’s far-right edge.
