There’s been quite a bit of misinformation on the internet about the Core Duo, and now, the Duo 2 CPUs regarding Windows XP Home.
Observe. Windows XP Home SP2, 2002 release.
Note the two CPU graphs.
This is standard Windows XP Home SP2, I have done nothing to enable this.
Note the processor affinity, with the two seperate defined CPUs.
I hope this has cleared up this bit of misinformation – you don’t need XP Pro, unless, well, you need XP Pro.
