How does Win8 enable allocation access?

Assigning access is a setting that allows you to restrict the use of only one Windows Store app to a specific standard account. For example, you can restrict a company's customers to use only one app in order to use your computer as a kiosk.
When customers sign in with a specific account, they can only use the app. They can't switch apps or close apps with touch gestures, mouse, keyboard, or hardware buttons. They also don't see any app notifications.
To enable assigned access, you need to log in to your computer with an administrator account and a standard account on your computer that has at least one Windows Store app installed for distribution access.
