PowerShell 6 can be downloaded and run side-by-side with the official Windows PowerShell. If you’d like to test-drive it, head over to https://github.com/PowerShell/PowerShell/releases, and pick the release that suits your platform.
Be aware that it is a hefty 50MB download. After unpacking/installing the release, there will be a new PowerShell icon in all black, representing PowerShell 6. The name has changed as well: the executable no longer is named “powershell.exe” but instead “pwsh.exe".
