WMI is a huge subject, so therefore it is practically impossible to provide a comprehensive example program that covers anything. However, the book �Network programming in .NET� (Buy at Amazon UK) (Buy at Amazon US) covers a much wider scope of WMI, and explains how to leverage it to access the bounty of information held within this vast, yet simple object model.
