When PowerShell 3.0 was released one of the little “surprises” was that the help included in the download was a short stub. If you wanted the full help available in your PowerShell session then you need to use the cmdlet Update-Help. While i’ve now gotten over the shock (I’ve adapted to just using Google) it is still important to find out what is changing in the documentation.
With that in mind I suggest you pop on down to Richard Siddaway’s blog and use the link provided to put into your RSS reader of choice. It never hurts to keep an eye on what they are up to over at MSHQ.
