In this blog post I show how to find out the Version of PowerShell on the localhost and on remote computers.

The release number of the PowerShell version can be found in many ways: Registry, Skripts … and of course in PowerShell itself.

Checking version of PowerShell (localhost)

Open Windows PowerShell with administrative privileges. Run Get-Host with Select-Object.

Get-Host | Select-Object Version

Simplified:

(Get-Host).Version

More simplified:

$host.version

$PSVersionTable.PSVersion

User-friendly:

$host.version | Out-GridView

User-friendly 2:

Write-Host (get-host).Version.Major (Get-Host).Version.Minor -Separator .

How to get PowerShell Version on Remote Hosts (Domain Environment)

Single Computer

Invoke-Command -Computername client001 -Scriptblock {$PSVersionTable.psversion}

Client001 is running 5.1.

Multiple Computers

First, get a list of computer names by running Get-ADComputer. Then use that list to get the powershell version of all computers.

$adcomputer=(Get-ADComputer -Filter *).Name

Invoke-Command -ComputerName $adcomputer -Scriptblock {$PSVersionTable.psversion} -ErrorAction SilentlyContinue

Cool. That looks good. All computers are up-to-date.

Non-Domain Computers

If the computers do not share the same domain, then you have to configure them as Trusted Hosts. For more information see my article PowerShell Remoting: How to connect to Remote Hosts in a Domain- and in a Non-Domain Environment (Trusted Hosts).
