Today Windows 10 and Windows Server 2019 ship with Windows PowerShell 5.1 as the default version. PowerShell Core 6 is a new edition of PowerShell that is cross-platform (Windows, macOS, and Linux), open-source, and built for heterogeneous environments and the hybrid cloud. PowerShell 6 today is a side by side version next to Windows PowerShell 5.1. That means on Windows you cannot just upgrade to PowerShell 6, you will need to install it, same as on Linux and macOS. This blog post just shows you how simple you can install PowerShell 6 or update PowerShell 6, if you have already installed it, on Windows 10, Windows Server 2019 or Linux.

Of course you can find great documentation out there on Microsoft Docs. However, Steve Lee (Microsoft Principal Software Engineer Manager in the PowerShell Team) shared some one-liner, which help you easily install and update PowerShell 6.

Install #PScore6 on Windows using a single command line from Windows PowerShell: iex “& { $(irm https://t.co/oXHZpO8yPJ) } -UseMSI -Preview”

You can look at the script to see what switches are available, this will use the MSI to install latest Preview.
