Windows Management Framework 3.0 and PS Remoting

Hello, after upgrading my Windows 7 x86 clients to WMF 3.0, I can no longer PS Remote to those machines (using Invoke-Command or Enter-PSSession).  The same update, applied to Windows 7 x64, does not render the same results, these clients still work fine.  The same goes for Windows Server 2008 R2 machines.  If I uninstall the update, the functionality comes back for the x86 clients.  Has anyone else seen this behavior?

Thanks!
