Installing various versions of PowerShell
Over the years, there have been many releases of PowerShell. Initially, Windows PowerShell was built on the .NET Framework and only worked on Windows systems. With the current release, PowerShell Core uses .NET Core 2.x as its runtime. PowerShell Core supports the Windows, macOS, and Linux platforms.
