Have you looked at PowerShell 3 yet?

PowerShell, the nifty .NET based object-oriented command prompt for Windows has matured during the years that the technology has been available. PowerShell is also a technology that is in active development, and the next version is already in horizon.

In the new PowerShell version, we are going to see an improved ISE (Integrated Scripting Environment), new commands and of course, a bit more power. The first CTP version has already been available since around September, but just a couple of days ago, Microsoft posted the CTP2 version for everyone to download.
