Recently write drivers and make a installer. But it is found that there is always a "unknown signature driver" when installing. This prompt box will not occur only if you manually change the system -> hardware -> Signature Device Driver. But I don't know which position in the registration table, I collected some information online, and finally I found related articles in "Drive Development Network", which is to modify the Software // Microsoft // Driver Signing and Software // Microsoft ////miROFT //////. Non-Driver Signing // This is connected to the policy to change the value! I have been tested, I found that I still have a prompt on my machine! ! Do I want to be under the registration of the current user? As a result, it was found that there was another Software // Microsoft // Driver Signing button under Key_Current_User! ! Change the value to 0! by! ! !
The following is the installation script of InstallShield! ^ _ ^
