Q:

Device manager vs wmi core count

A VM Windows 2008 R2 server was just setup with 12 cores and 12 GB ram.  When I look at Task Manager only 8 cores show.  When I look at WMI only 8 cores show.  Looking in Device Manger 12 processors show.  Can someone explain the difference between the core count in Device manager vs. WMI?
We have three machines with this config and they all show this way.  In addition Computer Properties only says 4 processors; which matches with the 8 cores reported in WMI (4 * 2).  
Oh and there are 12 cores allocated to this VM in the VMWare configuration
Is it that the Windows 2008 R2 license/version only allows up to 4 CPU?  Is there a way I can check?

A:

The operating system is Windows 2008 R2 Standard which only supports 4 processors.  
So even though there are 6 processors installed, 12 cores, only 4 processors, 8 cores are usable.  
I will ask our vitalization team if there is a processor they can emulate which contains 4 cores per processor.  Not sure if that is possible.
