Roku Controls With PowerShell

This is a GUI I created that will interact with any Roku boxes that may be on your network.  Not only that, I was able to figure out how to convert some c# to PowerShell to send out SSDP broadcasts for network device discovery.  This enables the GUI to discover any Roku boxes without having to know the IP address off hand.  It is not complete, but works well.

Powershell WSUS Client Front End

This is a script that I wrote which uses the WSUS APIs in windows (COM) and presents the user with a GUI to select and install updates.  I was very happy to learn how to use a listview .NET control in this exercise.
