How to Add and Remove Apps #LOB on #W8

You can add line-of-business (LOB) Metro style apps to a Windows® image by
using Windows PowerShell® or the Deployment Image Servicing and Management
(DISM) platform. LOB applications do not have to be certified or installed
through the Windows Store, but they must be signed with a certificate that
is chained to a trusted root certificate. To install Metro style apps that are
not part of your business line, you must use the Windows Store.

The Dism.exe and Windows PowerShell commands only add, inventory, and remove
Metro style apps, you cannot use them to install traditional applications that
can only be run on the desktop.
