I have with me my Acer laptop and it works quite well. I recently formatted it, and now in search for windows 7 for it. I want to upgrade it with windows 7 because I had windows xp in it before. I have heard that windows 7 are much better than windows xp. I will be very glad if you will tell me how I can easily get windows 7 for my laptop, as if I donât want to pay money for it. Any help will be appreciated.
