There are number of versions in PowerShell before. The first version of PowerShell is created using .NET Framework and it was only for windows computers. The latest version of PowerShell, PowerShell Core is made by .NET Core 2.x and it currently working with Windows OS, Mac OS and Linux Platforms.

If you are intereted in PowerShell 6 or any other version which comes after the version 6, you have to install the PowerShell Core. In Windows there are two main methods to use powershell. You can use Windows PowerShell and Windows PowerShell ISE as PowerShell. When it comes to windows servers, servers which include a GUI - Graphical User Interface we're calling them as DESKTOP editions. For the servers which do not include GUIs, we calling them as CORE editions.

If you are using a core edition of windows, when you logged in you will display a command prompt. To start script, just type shellscript in the command prompt and press enter. Then it will automatically go to script. But if you want to out from the shellscript, just type the "exit".  To open the shellscript in a desktop edition, just click the windows button in left lower corner and type "shellscript" or "shellscript ISE" for your need.

Assume that you want to check the version of ShellScript to continue your work. Just open the ShellScript window and type $PSVersionTable  and press Enter. Then there will be list of values in here like, PSVersion, PSEdition, PSCompatibleVersions, BuildVersion, CLRVersion, WSManStackVersion, PSRemotingProtocolVersion, SerializationVersion. Just pickup the value of PSVersion value as the current version of your ShellScript.

If you want to run the ShellScript with administrative privilages, just click on the windows button in left corner and type shellscript, then the shellscript will get display. Then right-click it and select "run as administrator". Then it will open with administrative privilages.
