Don't slipstream XP sp3 on Windows Vista!
 

So I build a new Windows XP ISO with SP3 integrated, this is a Volume License editions (VOL) which only accepts Volume License Keys (VLK). When I want to install it on a clean machine, I noticed that setup prompts for a product key and it does not allow me to continue, which should be a new feature in XP sp3. OK so I fill in the VLK but it does not accept it, I try another one from a customer of mine, does not work either.
