Hello. I've been looking at the Windows 8 Pro Upgrade download option (the 40$ one from MS) but I can't seem to understand a little detail about it's license and I was hoping somebody here could shed some light on the matter. I currently have a laptop running Windows 7 Ultimate activated with Daz's loader and I can buy the upgrade for it. The question is: if I buy the upgrade using this laptop will the license key allow me to use Windows 8 on another machine (if, for example, I replace my laptop) or will it be bound to the machine for which you buy it? Thank you.
