PowerTip: Determine PowerShell Version on Your System

Summary: Learn how to determine the version of Windows PowerShell installed on your system.

 How can I discover the version of Windows PowerShell that is installed on a particular system?  

 Use the $psversiontable built-in variable to get a display such as this:

Name                           Value

—-                           —–

PSVersion                      4.0

WSManStackVersion              3.0

SerializationVersion           1.1.0.1

CLRVersion                     4.0.30319.34014

BuildVersion                   6.3.9600.17090

PSCompatibleVersions           {1.0, 2.0, 3.0, 4.0}

PSRemotingProtocolVersion      2.2

The first line of the results tells you the current Windows PowerShell version. This variable was introduced with
Windows PowerShell 2.0. If you get nothing back, it’s Windows PowerShell 1.0.
