<p>If you are a student with a edu address, you can order a retail or download copy of Windows 7 Home Premium or Professional. You can also choose between an upgrade or full version. Imo, the best option is to order a retail box of Professional from Microsoft directly. More info here:</p>
<p>Windows</a> 7 Home Premium Upgrade $30 for College Students - SlickDeals.net Forums</p>
<p>Some engineering majors (I know ME/EECS/CS get it for sure) and all business majors get Windows 7 Pro and other software for free. 
</p>
<p>The rest (engineering majors) get at least Windows Vista/XP for free.</p>
<p>Just go to MSDNAA, look up UC Berkeley/your major and email the Program Administrator for a login info and download away.</p>
<p>why do we need to order by Wednesday? I have been told we have until January to order</p>
<p>It’s free if you enroll in a CS course for a semester.</p>
<p>I am not completely sure, but I believe this is a pre-order promotion, meaning that you need to order before it gets released. I would also like to mention that free versions offered above are not boxed copies, so if you want a boxed copy this is the cheapest you will see it.</p>
