Though there are no specifics on how it’s done, several technology sites are pointing to an article in a German tech magazine that allegedly has step-by-step instructions on how to convert Windows XP Home Edition to XP Professional just by changing a couple of registry keys.

C’Ts online site is not reporting about it - guess they want to maximize print magazine sales. The article is in the c’t 12/05 on page 148. The hack requires several steps. The major change is in a registry file setupreg.hiv in the i386 folder. The article is 8 pages long.

One can reasonably expect the details on how this is done will be online in short order.
