I have mentioned PowerShell Community Extensions many times over the last few years. I have found them a very useful set of utilities to extend the basic PowerShell install. With PowerShell v2 there was an irritation that a few of the cmdlets
overrode the PowerShell v2 cmdlets of the same name.
That has been fixed with the PSCX v2 beta that is available from http://pscx.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=39405. It is module based so use it on PowerShell 2. It is a simple zip file, so download it, unblock it and unzip it to your module path.
It loads using import-module and looks to be full of goodies. The PSCX guys have done a good job with this. Time to give it a whirl and see how it works.
