Windows 7 on HP Proliant Server

Hi,

My Server specs: 4 CPUs (Physical) with each CPU has 2 cores. (total 8 cores)
32GB RAM

I managed to install Windows 7 Ultimate on it but it detects only 2 Physical CPUs (4 cores).

Is there anyway (I really doubt it but just want to get it confirmed) that We can make Windows 7 support 4 Physical CPUs?

Unfortunately, Windows 8 (Pro) too seems to be supporting only 2 Physical cores!

Thanks!!

Don't think so. Will WHS not work?
