You mean downgrading to Vista 
There isn't really anything extra that you could, or would want to make use of.
There all as horrible as each other :headbang:
I think the Minimum required memory for Vista (to run properly) is 2GB... at least thats what i was told.
But my Dad is running it on his Machine with only 1GB.... so should be fine.
Honestly.... I would stick with XP... at least until they Iron out all the bugs.

"Yes."
