If I’m performing a an upgrade to Windows 8, do I have to have the previous version installed, or is just having the key enough?
I have an old laptop with windows xp installed on it. It has a broken battery and I don't use it anymore. I have a new build coming up, and I'd like to have windows 8 on it. I have no idea where the original windows xp disk is that came with the laptop.
My question is: What is required to use that xp license for the windows 8 upgrade? Is there any way to upgrade to windows 8 pro, using the software upgrader or the more expensive dvd upgrade, that just allows you to plug in a valid windows xp key and upgrade? Or do those require you to run the upgrade on the existing install?
