I am running a 4400 dual core and would like to know if I can use Home or if I should use Corporate if I have the option. I know there is a hotfix for Home XP that addresses dual core support, but how well does it work? Is Corporate any better? Also, the rest of my home computers run Home, so if I ran Corporate, would I be able to network them? I have access to both disks, but Corporate sounds like a pain in the neck for a home network.
