How to prevent a Metro App from running using Applocker

In Windows 8 the Applocker feature has been extended to support management of metro style apps. Enterprise administrators can define a Packaged app Rule to allow or deny the installation and/or use of a particular metro style app. When opening the Group Policy editor under Computer Configuration / Windows Settings / Security Settings / Application Control Settings / Applocker there is a new node called Packaged app Rules.
