Powershell is one of the most popular command-line tools in the world. Aside from being used by most system administrators, it is also installed by default on Windows devices and is extremely powerful making it the go-to tool to quickly get anything done from small tasks to large automated processes.
What is PowerShell
Officially, Windows PowerShell started in 2006, when it became the new name for what Microsoft up to then had called "Monad". From the start, it was positioned as part of Microsoft's management technology offerings, finally allowing Windows users and admins to use a command-line interpreter (CLI) that isn't limited to basic commands and a basic scripting language.
In 2016, PowerShell went open-source and also cross-platform and now resides primarily on the GitHub page. Over the years Powershell has developed itself into an automation and configuration tool/framework that is optimized for dealing with structured data (e.g. JSON, CSV, XML, etc.), REST APIs, and object models. Additionally, it includes a command-line shell, an associated scripting language, and a framework for processing cmdlets.
Powershell Lifecycle
Microsoft PowerShell follows Microsoft's modern lifecycle policy. Microsoft uses this policy for most products that are services and supported continuously and the products are supported if they meet the following conditions:
- Customers must stay current as per the servicing and system requirements published for the product or service.
- Customers must be licensed to use the product or service.
- Microsoft must currently offer support for the product or service.
The wording of this policy is very vague, so it's best just to look at the PowerShell lifecycle page.

Find Outdated PowerShell Installations
Most devices will likely be running the default pre-installed Powershell version 5.1. However, Windows doesn't list this as installed software, and it is also still supported as it is provided with Windows. If you are running PowerShell 7, you can use the report below to get a complete color-coded overview of your PowerShell installations along with the end-of-life date so you're always prepared for when support is stopped.
