Overview

Windows PowerShell is Microsoft's task automation framework, consisting of a command-line shell and associated scripting language built on top of, and integrated with, the .NET Framework. PowerShell provides full access to COM and WMI, enabling administrators to perform administrative tasks on both local and remote Windows systems.

In PowerShell, administrative tasks are generally performed by cmdlets (pronounced command-lets), which are specialized .NET classes implementing a particular operation. Sets of cmdlets may be combined together in scripts, executables (standalone applications), or by instantiating regular .NET classes (or WMI/COM Objects). These work by accessing data in different data repositories, like the file system or registry, which are made available to PowerShell via Windows PowerShell providers.
