Quick question to ask the SUPER brains of msfn. if i remove the Windows XP serial # from the winnt.sif then each time i would install Windows XP it would ask me for a valid serial correct? the reason why i am asking this is bec., a friend of mine is offering to pay me to make a Unattended Windows XP for him. I told him sure, only if he has a valid serial no, that isn't pirated. I don't trust him to say the least. going back to my question by removing the serial from the winnt.sif then each time the unattended xp is loaded it would ask for a serial.
