right I'm running vista on my computer but i need to have xp on there as well is there anyway i can put vista on my account and xp on the guest account ??
assassin's creed wont play on my computer and i assume it is down to the version of vista i have.
if you dont need full access to your PC hardware eg 3D graphics go with vitrualising, VMware workstation my preference but microsoft virtual pc will do, otherwise go the dual boot route.
