so can you please explain exactly how to change a vlk xp sp3 clean install to a genuine oem xp pro WITHOUT USING the 911medic tool ? so far I installed windows vlk.. found the string in the bios that say "genuine c&c", downloaded the oembios files and the 2 dlls from microsoft service pack 3, put them in the right places using a linux live cd, set the attribute of oembios.cat to "system" going in safe mode, but the system now says that it is not sure it is authenticathed and I cannot login any more.. I guess I'm forgetting some thing.. maybe to change the cdkey with an slp one ? and what is the slp key for genuine c&c brand ? and how to change the key on an already installed windows ? please help
