Updated November 25, 2015: One of the most popular posts I have ever published at ZDNet was this one, originally titled Seven perfectly legal ways to get Windows 7 cheap (or even free). I wrote it in late 2009, and posted a follow-up one year later If you had followed my advice, you could have saved hundreds of dollars on upgrades and special deals for students and IT pros.

But it is indeed still possible to find great deals on PCs running Windows 7, if you know where to look.
It's also possible to tweak and tune newer Windows versions so that they are functionally equivalent to Windows 7. In that spirit, I've completely reworked this post with information that reflects the current PC market. [Last updated November 25, 2015] Windows 7 is officially middle-aged. It was publicly released more than six years ago, on October 22, 2009.
