Apps are granted access to some devices by default. For Windows Store apps, this includes access to print and scanner devices. To access other types of devices, you must specify them using a DeviceCapability element. Some device capabilities must be added to the package manifest manually. For more info, see How to specify device capabilities in a package manifest.
For more info about capability declarations, see App capability declarations.
Some device capabilities require child elements. This table lists device capabilities by name or GUID and specifies if any child elements are required.
