One of my favorite features in PowerShell v2.0 is the ability to add help scripts and functions. The help system with cmdlets is terrific.

There have been some changes since PowerShell CTP3 so if you want the absolute latest PowerShell bits you’ll need Windows 7. Here’s what you can look forward to.
