Let's say I'm a complete computer noob and know nothing beyond very simple steps in the Windows OS. Let's say I had a laptop running Windows Vista, which at its very best only can run FFXI with up to 20 FPS. Now let's say I wanted to "upgrade" from Vista to XP, to see if FFXI could run better without the system resource hog that is Vista.
Where do I start? Talk to me as if I know nothing.
