This comprehensive guide covers essential PowerShell information, including features, system requirements, and how Microsoft’s framework extends to task automation and management.
PowerShell was developed more than 10 years ago by Microsoft to expand the power of its command line interface by coupling it with a management framework used to manage local and remote Windows, macOS, and Linux systems. By using the Component Object Model, Windows Management Instrumentation, and Common Information Model interface standards, PowerShell allows for managed elements of computing objects to be administered independently.

Executive summary
- What is PowerShell? Microsoft’s PowerShell is a management framework that combines a command-line shell and scripting language that is built upon the .NET framework for native Windows support or the .NET Core framework (which is open source), providing cross-platform support for Windows, macOS, and Linux.
- Why does PowerShell matter? PowerShell can automate management tasks and function as a dedicated scripting language for both Microsoft- and non-Microsoft-based software. PowerShell includes commands called “cmdlets” that add functionality to the core foundation while providing a means to upgrade/update cmdlets.
- Who does PowerShell affect? It can impact companies relying on Microsoft, Apple, and Linux services to empower their business functions and the IT professionals responsible for managing this infrastructure.
- When is PowerShell available? PowerShell 7.4.6 is open source and the most recent version available, supporting Windows, macOS, and Linux operating systems. On Windows systems only, both versions may exist side by side without conflict.
- How can I get PowerShell? PowerShell 5.1 (.NET) is a natively installed application that is part of all Windows client and server OSes; by default, the application can be updated directly from Microsoft’s downloads website or through Microsoft Updates. You can get the latest version, PowerShell 7.4.6, by visiting Microsoft’s GitHub website for PowerShell and downloading the version that supports your operating system; this version of PowerShell may also be downloaded and updated via the native CLI of the operating system.
