If I download Vista from their website (Windows Market Place), can I burn it...

...install it on a different PC? My desktop has a virus, and I need to re-install Windows. I was going to purchase Vista from their website...but I want to make sure I can do that first. I'd be downloading it on a different computer and burning it. Is this possible?I live in a small town, and the stores only carry the upgrade version. I'd use that, but I have a "borrowed" copy on my computer from a friend, and I want to ensure that it installs properly, so I'm going all out for the full version.Again, I just want to know if I can burn Vista onto a disc to use on a different computer. I'd only be installing it once, and I'm well aware that you have to activate, etc. I'm not trying to do anything illegal, I just want a running desktop.Thank you.
