PowerShell should raise the bar for lowest common denominator of scripting on Windows systems. I've dabbled a bit it, but I was disappointed it was so tightly coupled (possibly by necessity?) with the .NET runtime version. This makes it much more difficult to update on old systems. I had to write PowerShell in the oldest compatible version. It's almost like dealing with JavaScript implementations of all versions if IE. Other scripting langues like Python provides user-space virtual environments with forward/backward compatibility. Does PowerShell have a universally available package manager (ie. Windows Update)? I don't spend much time in the Windows world. But, the friction of using PowerShell was higher than my tolerance.
