I have a couple year old Dell Computer that had Windows XP Home on it. I have the Registration Code but I don't have the original Reinstall disk for it. I need to do a clean reinstall of XP Home. Unfortunately, I think at one point in time XP Pro got installed on this computer. I know that it is going to have to be a Full reinstall since Microsoft won't just back down from Pro to Home. Can I: - Use a Windows XP Pro Disk and use my Home Registration Code? - Use a Windows XP Home Disk that that came with an Acer Laptop and use my Home Registration for the Dell? - Should I just break down a get version of XP Home? - Any other suggestions? Thanks.
