Hi All, In Windows XP, When we  RightClick on My Computer and  select properties -> hardware ->driver signing . there we see a check box "make this action the system default" under administrator policy .  can we check or uncheck this box using any registry value ? If yes, what is registry value to be used ? or  By changing any registry value can we install an unsigned driver without getting "continue anyway" message ?? Please reply to me, if u have the answer for this. I need this urgently.
