Which version of PowerShell am I running?

To find out which version of PowerShell you're running, use:


If the variable doesn't exist, you can assume it's version 1.0.

(From https://stackoverflow.com/questions/1825585/determine-installed-powershell-version).

Use Get-Module to report installed modules and versions:

Get-Module -ListAvailable

(Without -ListAvailable, Get-Module lists only modules that have been imported into the current session).
