Most of the time we have been used to cmdlets and it’s various features but do not know about the version and hence this post might help some of you to understand in finding different versions of PowerShell and how to switch between versions (provided multiple versions are installed on your Machine). I’m using Where clause syntax to explain version switching.
Code to find version-
PS:\>Get-Host | Select-Object Version
Version
——-
2.0
PS:\>$Host.Version
Major Minor Build Revision
—– —– —– ——–
2 0 -1 -1
PS:\>$PSVersionTable.PSVersion
Major Minor Build Revision
—– —– —– ——–
3 0 -1 -1
Switch between versions -
Goto Cmd Prompt and type the below command
C:\> Powershell -version 2
PS C:\>Get-Host | select Version
#v2 syntax
PS C:\> Get-Service | Where {$_.name -like “*SQL*”}
Status Name DisplayName
—— —- ———–

Running SQLWriter SQL Server VSS Writer
PS C:\> Get-Service | where name -like “*SQL*”
Error Message -

C:\> powershell -version 3
PS C:\> Get-Host | Select Version
PS C:\> Get-Service | where {$_.name -like “*SQL*”}
