I have an MSDN Academic Alliance account from my university. I have downloaded from there Windows 7 x64 and I am currently using it on my desktop PC.

I recently bought a laptop, and I want to install Windows 7 x86 on it. But I have noticed that I get the same key for Windows 7 x86 and Windows 7 x64 from the site I use to get the Microsoft software (that site is

So I have this question: Can I install Windows 7 x86 on my laptop, and Windows 7 x64 on my desktop, using the same key? Or will that get me into trouble when I reinstall Windows?

I know when I did the same thing I received separate keys for x86 and x64. I guess it either differs based on school, or they must have changed it :( – Ryan Versaw Dec 24 '09 at 15:44
There is something strange going on here... I remember that I had the same key for x86 and x64, but now I went to the site and checked, and I have different keys for the different versions. Oh well. Thank you guys anyway :) – Ove Dec 24 '09 at 16:17

The key will work fine, however you should not install on more than the total number of computers you are allowed to use.

I believe that if it is for personal/research/education use, you may install it on as many computers as you wish... and keep it after you graduate - you simply are not allowed to install any more copies after you graduate and your MSDNAA expires.

In addition, while in school (and after you graduate) the install is only good for personal/academic purposes - not commercial purposes. – Ryan Versaw Dec 24 '09 at 15:44
So, after I graduate, if I want to reinstall my PC, activation will fail? – Ove Dec 24 '09 at 15:48
Technically no, but you will be braking the licensing agreement. – William Hilsum Dec 24 '09 at 15:55

As long as you're licensed, a single key isn't particularly unusual. I haven't dealt with MSDNAA in about 5 or 6 years, but my company is enrolled in MAPS and Microsoft issues us a single CD key for Win7 Pro for 32/64 bit with 10 licenses. Same deal with their other volume licensing programs I've dealt with.

i don't think MSDNAA is under volume licensing – Jonathan Dec 28 '09 at 3:16
