Go to http://www.win741.com/. Click on the Buy link which is the first picture in the second row. It will take you to a page filled with more details regarding purchasing Windows 7. This deal ends January 3, 2010 at 12:00 am CST. So you have a little bit of time to scrape together the money to purchase it.
Now this is for Windows 7 Home Premium or Windows 7 Professional. You can only purchase one copy per student. You can Also get the 32bit version or 64bit version. I recommend going 64bit.
You will need an .edu email address or you can upload a digitial scan of one of the following items:
- Student ID card
- Class list
- Proof of course payment.
