I have a Dell laptop with Microsoft Windows Vista as the operating system on it and I am a student. I want to get Windows 7 with the student discount for $29.99. Is there any difference at all between the full priced Windows 7 for like $200 or the student discount Windows 7 for $29.99? I just want to make sure that the huge discount doesn’t cost me later down the road with something else and that it is worth it.
