What makes XP CD's different? Why is an OEM CD and OEM CD? How is that different from a retail version? How does Retail differ from Upgrade? I have an open question that seems to revolve around this issue. I need to "Repai" of "Upgrade" an existing XP install. But for some odd reason, my XP CD's do not show this option, though I know I have seen it before.
What is the magic that makes the CD force an upgrade install ON BOOTING from the CD? I can't simply stick the CD in and do the upgrade, because the installation of XP is damaged and will not boot.
If anyone knows how the installation CD differ in personality, do you know if I can use my current keycode with the various permutations of XP?
