How to find powershell version
From Svendsen Tech Powershell Wiki
There are several ways to find which version of PowerShell you're running. I demonstrate the ones seemingly most relevant here. If you've looked at the directory structure and found "v1.0" - don't be fooled - it can still be Powershell v2 or later. From what I've read, Microsoft originally had planned to use different directories, but later changed their mind - probably for backwards compatibility reasons if I am to venture a guess.
There's a list of all the different PowerShell executable file system locations here in this article.

Displaying PowerShell Version With PowerShell v2 and v3
- Start PowerShell. If you don't know how, click here.
- With PowerShell v2 and v3, you can enter $PSVersionTable at the prompt:
PS C:\> $PSVersionTable
Name Value
---- -----
CLRVersion 2.0.50727.5446
BuildVersion 6.1.7601.17514
PSVersion 2.0
WSManStackVersion 2.0
PSCompatibleVersions {1.0, 2.0}
SerializationVersion 1.1.0.1
PSRemotingProtocolVersion 2.1
Displaying PowerShell Version With PowerShell v1
With PowerShell version 1, you can inspect the variable $host and the property Version to see which version of PowerShell is running. PowerShell version 1 doesn't have the $PSVersionTable variable mentioned above. The $host variable is in PowerShell v2 as well.
- Start PowerShell. If you don't know how, click here.
Currently this is the output from PowerShell v2 (I actually don't have any computer still running v1 around):
PS C:\> $host.Version Major Minor Build Revision ----- ----- ----- -------- 2 0 -1 -1
Using Get-Host
You can also use the cmdlet Get-Host:
PS C:\> Get-Host Name : ConsoleHost Version : 2.0 InstanceId : a3a9b37c-61a4-478d-bcf6-b3e0f1b93f26 UI : System.Management.Automation.Internal.Host.InternalHostUserInterface CurrentCulture : nb-NO CurrentUICulture : en-US PrivateData : Microsoft.PowerShell.ConsoleHost+ConsoleColorProxy IsRunspacePushed : False Runspace : System.Management.Automation.Runspaces.LocalRunspace
Beyond Basics
Yet another way, that returns the same as "$host.Version" in my PowerShell v2, is looking at the default runspace:
PS C:\> [System.Management.Automation.Runspaces.Runspace]::DefaultRunspace.Version Major Minor Build Revision ----- ----- ----- -------- 2 0 -1 -1
