German computer magazine C’T is reporting a procedure that will let you change Windows XP Home Edition to Windows XP Professional just by changing two bytes in an installation file (implying, at least to us, that it can only be done on a fresh install, not an existing one). There’s no information online, though, so if anyone has the magazine and would like to give us a more detailed breakdown, we’d have 1000 dankes for you.
