Increasing the number of visible CPU cores in a Windows 7 VM

I recently had to upgrade a Windows 7 VM from two cpu's to 4. After I added them and turned the VM back on, it only showed two cpu’s in task manager even though it showed 4 cpu’s in device manager. The following link shows how to edit the configuration parameters for the VM so it will show 4 cores in task manager. I had to set 'cpuid.coresPerSocket' to '2' for all 4 cpus to show up.
