Hi. I have a scenario that I would like some clarification on. I have an older computer running an activated XP PRO OS. I have alot of programs and peripherials attached to it but it is slow and somewhat unstable. I've acquired another computer (no OS) that will have a blank, formatted drive that I would like to use as its replacement. Ideally, I'd like to run them side-by-side to ensure that everything transfers over to the new machine but I've only got the one OS. Can I load it onto the new machine at the same time that its running on the old one? How does MS's activation work in this scenario? Do I have to call MS to get permission? I'm not planning to use the old box once the new one is up and running. Thanks for your help.
