What is PowerShell?

PowerShell commands are called cmdlets, which allow computer management with the command line. The tools in PowerShell allow access to data warehouses such as Registry and Certificate Store as easily as accessing file systems.

In addition, PowerShell has a rich display parser and a fully developed scripting language. Simply put, you can complete all tasks like working with the user interface and more.
