Windows PowerShell is an extensible command-line shell and associated scripting language from Microsoft. Windows PowerShell integrates with the Microsoft .NET Framework and provides an environment for execution of cmdlets, which are specialized .NET classes implementing a particular operation, scripts, which are composition of cmdlets along with imperative logic, executables, which are standalone applications, or by instantiating regular .NET classes. These work by accessing data in different data stores, like the filesystem or registry.
