Windows PowerShell, the extensible command shell from Microsoft, which is based on object-oriented programming and the Microsoft .NET framework, provides powerful and customizable completion capabilities similar to those of traditional Unix shells.
It has since been bundled with all subsequent versions of Windows. 10 years later, PowerShell went open-source and cross-platform. It can operate both interactively (from a command-line interface) and also via saved scripts (.ps1 files).
