windows 8 upgrade license.

[rare]

I installed windows xp on a partition of my macbook air and recently upgraded it to windows 8 via the download upgrade. But I've hardly used it on the macbook since, is it possible to erase the install and use the same license to upgrade my windows 7 machine? Or would I need to spend another £25.

Cheers guys. I will give it a go. Seems like too much common sense in a Microsoft license agreement to actually be real

Just to confirm, works fine! Created an ISO on a DVD, booted from the DVD wiped windows 7 install deleted partition etc etc, allowed me to install windows 8 as a totally clean install all I had to do was phone up activation which was a piece of cake!

Impressive Microsoft!!
