What is Windows PowerShell?

It is built on the Microsoft .NET Framework and provides fully automated system administration tasks to IT professionals to help them increase productivity. In other words, Windows PowerShell is an integrated version of the VBScript and windows command prompt cmd.exe that is a user-friendly language that helps in controlling and automating administration task system.

The objective of PowerShell is to provide command-line tools (called cmdlets or ‘scripts’ in simpler language) to automate repetitive tasks. There are as many as 129 cmdlets for performing common system administration tasks like managing services, processes, event logs, certificates, the registry, and using Windows Management Instrumentation (WMI).
