Windows 7 upgrade install question

[Grimley]

Right, I'm about to do a new build & install win 7 Upgrade.

Now in the past I could install a full version of XP onto a PC using a XP upgrade disc onto a formatted HD, all it would do is ask me for the win98 disc before going ahead with the install.

Now I still have win XP OEM, XP upgrade retail & Vista OEM discs.

My question is, could I do what I did with a win 7 upgrade disc that I used to be able to do with the XP upgrade discs using any of the discs I still own?

Thanks.

Yeah you can, follow this:

In the article above it mentions it being illegal, however if you read this article : http://www.infoworld.com/d/windows/microsoft-confirms-windows-7-clean-install-trick-legal-191

they explain that you must stop using the Windows version you would have originally upgraded from.
