How to find the Windows version from the PowerShell command line

Question

How do I find which Windows version I\'m using?

I\'m using PowerShell 2.0 and tried:

PS C:\\> ver
The term \'ver\' is not recognized as the name o         


        

Answer 1

$OSVersion = [Version](Get-ItemProperty -Path "$($Env:Windir)\System32\hal.dll" -ErrorAction SilentlyContinue).VersionInfo.FileVersion.Split()[0]

On Windows 10 returns: 10.0.10586.420

You can then use the variable to access properties for granular comparison

$OSVersion.Major equals 10
$OSVersion.Minor equals 0
$OSVersion.Build equals 10586
$OSVersion.Revision equals 420

Additionally, you can compare operating system versions using the following

If ([Version]$OSVersion -ge [Version]"6.1")
   {
       #Do Something
   }
