Chapter 4 has been released for PowerShell and WMI. It is available through the Manning Early Access Program (MEAP) at http://www.manning.com/siddaway2/
The first 4 chapters cover:
- Solving Administrative Challenges
- Using PowerShell

Chapters 5 and 6 covering System Configuration Information and Disk Systems respectively are in the pipeline. I’m currently working on chapter 7 on the registry. Chapters 5 onwards include lots of lovely scripts.
