powershell Get-NetAdapter command not recognized

Question

I am running Windows 7 Home Premium. I installed .Net4.5.1 and Powershell 4.0 It installed successfully. I can verify that because this command returns:

PS C:\Users\Aubrey\Documents> $PSVersionTable.PSVersion

Major  Minor  Build  Revision
-----  -----  -----  --------
4      0      -1     -1  

However I cant run commands or scripts:

PS C:\Users\Aubrey\Documents> Get-NetAdapter
Get-NetAdapter : The term 'Get-NetAdapter' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if 
a path was included, verify that the path is correct and try again.

Solution

According to http://blogs.technet.com/b/heyscriptingguy/archive/2014/01/15/using-powershell-to-find-connected-network-adapters.aspx, the NetAdapter module (and therefore the Get-NetAdapter command) needs Windows 8 or better.
