MetroApps Module by Tome Tanasovski 6 months ago

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
