When Windows PowerShell first came out, there wasn't much documentation to help people learn this new command-line and scripting environment. That's steadily changing. In fact, Microsoft recently released the Windows PowerShell Graphical Help File, which is a .chm file that contains the set of Help files that you'd normally access through the PowerShell command window. The PowerShell Graphical Help File (PowerShell.chm) can be especially helpful to those people who want to see what PowerShell offers without having to download it. The PowerShell.chm file contains not only detailed information about each of the PowerShell cmdlets but also useful information on scripting concepts such as arrays, operators, and parameters.
You can download PowerShell.chm from the Microsoft Download Center. If you're running Windows Vista, Windows XP, or Windows Server 2003, you can download version 2.0 from the Windows PowerShell Graphical Help File (Version 2.0) download page. If you're running an earlier version of Windows, you can download version 1.1, which works on Windows NT or later, from the Windows PowerShell Graphical Help File download page. No matter what version you download, you don't need PowerShell or the Microsoft .NET Framework installed. . . .
