Wsus report with powershell

Last Tuesday, someone in our department asked us if it is possible to get a report via email that displays information about failed computers.

By default Windows 2008 R2 does not provide WSUS cmdlets, so we need to load WSUS assemblies from .NET, here is a URL with the method and properties http://msdn.microsoft.com/en-us/library/microsoft.updateservices.administration(v=vs.85).aspx
