firefox sometimes does use a silly amount, but ive got 2Gbs of ram on my pc and it doesnt slow down at all so i dont give a shit how much it uses, id rather have a browser that uses more ram if it means its better than I.E

Well i can tell you know 85 processes is very high, when i had vista i had about 45-50, and on xp now im running 36.

Half of them are not showing because you needed to click "show all", but already i can see one or two things you can remove like itunes.

What you can do is when your bored or have time google each one and it will tell you what it is and if you can remove it, takes time but if your pc runs better its worth it
