This module provides two functions:
Get-MetroApp - This cmdlet reads the registry for the keys that have the launcher id and the entry point (interesting for xaml apps, but not so much for html5 apps)
Start-MetroApp - This cmdlet uses one of the ids returned by Get-metroapp to launch an app in the win8 metro interface
Apologies for the lack of get-help documentation, but I'll be doing a blog post about this shortly:

Original C# code modified slightly from here - also the registry info is on this page too:

// load the necessary components by communicating with a designer-specified service on
