It depends on what version of Windows you have on your computer (the version of Powershell).
On my windows 8.1 computer, I can get the version of powershell by running this code in powershell:
--------------
PS C:\Users\Jayaram> Get-host

CurrentUICulture : en-US
PrivateData : Microsoft.PowerShell.Host.ISE.ISEOptions
