Compliance Settings & Powershell Commands

Question

I have started using Configuration Baseline's and I followed a blog on how to add an inbound firewall rules via a Configuration Item using Powershell.  The Powershell script is using the commands 'Get-NetFirewallRule'
& 'New-NetFirewallRule' which work fine for my Windows 8 clients however those commands are not available for the version of powershell in the Win 7 clients.  The post was not OS specific and such it answer how you would use this for win 7 devices?
 Maybe I'm missing something and those commands would work on a Win 7 device...?
I'm hopefully making a good assumption that all Win 7 devices would have to have Import-Module NetSecurity' run in Powershell before we are able to deploy that Configuration Baseline calling those commands?  Am I
off here?  Is there a better way to go about this?  Or would I have to make two Configuration Item's by OS.... (Win 7 and Win8)?

Does your Windows 7 machines have WMF4 installed? I mean this:

As stated here
http://technet.microsoft.com/en-us/library/jj554860.aspx, the command Get-NewFirewallRule applies to Windows 8.1,
Windows PowerShell 4.0, Windows Server 2012 R2. With WMF4, you'll install PS4 to your Windows 7 machines. After that you can try your compliance settings again.
Some info on deploying WMF4 can be found through these links:

What you basically need is two applications, one for .NET4.5 and one for WMF4. Configure .NET4.5 as dependency for WMF4 and deploy WMF4.
