Good grief, I've been trying to troubleshoot for a long time now why only 2 cores show up in my task manager (active), yet in the device manager I see all 4. I have 2 physical processors, 2 cores each (Opterons baby).
Legit, just bought version of Home Premium.
I was under the impression that "as advertised" this product would support multiprocessing !!!
To my great disappointment, only one physical cpu is supported, unlimited cores !!

I wan't to sue Microsoft. What can I do, I don't want to be forced to upgrade to Windows Professional now that I just bought Home Premium !!!
