I am using Windows 7 64-bit for about a year now and to be honest i am not too much into it so i am confused i want to downgrade to windows xp professional but also at the same time i want to stay at Windows 7 64-bit, and suggestions on what should i do, by the way my PC Specs are the followings

-RAM : 4G DDR2
-CPU : Intel Core2duo 2~ghz
-HDD : 320 GB
-Graphic Card : Intel G45, shared 1g, dedicated 32 MB's

i like windows XP because of it's simplicity, however waiting for suggestions.
