Windows 7 missing/forgot VCPU's

I made a Windows 7 Virtual Machine (VM) with 2 CPU's and it worked fine. I then wanted to add 2 more CPU's to it for a total of 4 to test, but the VM would only show 2 CPU's. This is how I fixed it.
1.Power off the Virtual Machine (VM)
 2.Edit Settings on the VM

3.Select Options (red), General (blue), Configuration Parameters (green)

4.Click “Add Row” (black), Enter [ cpuid.coresPerSocket ] (pink), Enter [ 2 ] (yellow)

5.Click OK and power on the VM.
