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).

I don’t want to see the version of all domain computers, but only selective computers. How can I provide the list of target remote computers…
