Windows PowerShell is a Windows command-line shell designed especially for system administrators. Windows PowerShell includes an interactive prompt and a scripting environment that can be used independently or in combination.
Unlike most shells, which accept and return text, Windows PowerShell is built on top of the .NET Framework common language runtime (CLR) and the .NET Framework, and accepts and returns .NET Framework objects. This fundamental change in the environment brings entirely new tools and methods to the management and configuration of Windows.
