ABSTRACT
In an operating system, a shell is a computer program that provides a user interface. The user interface translates human readable commands into the code that can be processed by the operating system. For system management, each shell accepts a set of shell-specific commands that can be entered by users. Windows PowerShell is such a user interface provided by the Windows operating system. In the early days, PowerShell was designed mainly for server administrators. It was a separate package from the Windows operating system. Recently, PowerShell has been included in the Windows operating system to make it available to all users.
