Well recently I have purchased a computer for myself. I have windows xp operating system installed on my system. I want to know windows 7. My many friends have windows 7 operating system at their home. They say that windows 7 are far better than the windows xp. I have heard that windows 7 give full sized preview bigger button and we pin program to it on one click. Is this true? I want to know some reasons for why should I buy windows 7. So friends I want to know that windows 7 are really fast or its just a myth. What things make people buy windows 7? Kindly provide some good suggestions to me. Any suggestions regarding this would be highly appreciated.
