You can purchase a legal copy of Windows 7 from Microsoft for $29.99 if you have almost any .edu email address. The site they set up for it is www.win741.com You can only purchase one copy per approved email address. So if you have a university email address because you are a student or have a child who is taking any college classes, this is a pretty good deal. At least it looks like it. lol. I don't have enough free hard drive space on either of my desktops, so I haven't bought it. The sale ends January 3.
