I have Windows 7 Evaluation Copy build 7100 currently installed. I upgraded from Windows Vista Home Premium to this Windows 7. What I’m asking is that when Windows 7 is officially released on October 22, can I upgrade from this version to the retail version without having to reformat? Meaning I won’t lose everything on my hard drive?

I want to avoid using the £50 adapter and see if I connect the Xbox 360 to Xbox Live by using a computer or by other means. Please leave detailed answer and very specific details how to complete this action IF POSSIBLE.

I am about to purchase my first laptop, a Gateway NV5214u. Its my first PC aside from an old, almost unusable desktop. Ive grown up a Mac user and I am going into my sophomore year of high school. I really dont know much about these operating systems. I get a free upgrade to Windows 7 but to me (someone who is not too PC savvy) what are the major and/or noticeable differences between Windows Vista and Windows 7?
