I just got my dreamspark windows 8 64bit pro key, and I have a couple of questions. 1. Can I use that key to upgrade from windows 7? I'm too lazy to do a backup of everything and do a fresh install 2. How many license, ie.. computers can I install this key on? I want to at least install it on my desktop and laptop, then make a back up of the licenses to reinstall if needed. 3. How can I make a custom windows 8 dvd with that key and activation file, so that I can just pop in the dvd and it install and then activates on it's own? No matter how many reformat I have to do to both of my machines? I saw the guide for the AIO with the WMC but I don't have WMC so how do I do it with just the 64bit pro?
