PowerTip: Determine PowerShell Version

Doctor Scripto

Summary: Easily determine the version of Windows PowerShell that is installed.

Hey, Scripting Guy! Question How can I determine what version of Windows PowerShell is installed on my computer?

Hey, Scripting Guy! Answer Use the $psversiontable automatic variable, which is available in Windows PowerShell 2.0 and Windows PowerShell 3.0. 
          (If nothing comes back, you are running Windows PowerShell 1.0.)

PS C:> $PSVersionTable


Name                           Value

—-                           —–

PSVersion                      3.0

WSManStackVersion              3.0


CLRVersion                     4.0.30319.18046

BuildVersion                   6.2.9200.16434

PSCompatibleVersions           {1.0, 2.0, 3.0}
