Automate driver selection windows 7

[Smoblikat]

Hello, im creating an image for the computers at work and Ive run into an annoying issue. This is a universal image, Wn7X64 Pro, and im trying to automagically install the drivers for the graphics card. Sounds simple, right? Well, the new 7th gen processors dont support windows 7, so I made a custom driver .inf for it to install under windows 7. That part works fine, the drivers install and I get intel HD620 graphics as an option. Then I call dpinst from my unattend file and have it install the drivers for the GPU during startup with the /lm switch enabled (since its a custom driver, its unsigned and M$ doesnt like that for some reason). All of that works great, the driver installs during first startup, and I have a completely unattended install. The issue arises when I boot into windows for the first time. The driver is technically installed, and it is available, but windows doesnt automatically select it for use. I have to right click the device in device manager, select update driver etc.. and I see the custom one right there in the list of currently installed drivers, right under "Standard VGA graphics adapter". All I do is select it an hit install, and it works perfectly. Does anyone know of a way to force windows to select that specific driver to use over the default one? I cant help but imagine this is all related to it being unsigned and therefore "worse" than the default one, so im experimenting with putting
<forceIfDriverIsNotBetter/>
in my dpinst.xml file. Ill let you guys know if that solves it, but if anyone has any ideas please oh please share them with me.

Using that switch didnt seem to help, I still see both the HD620 and standard VGA graphics adapter options in the driver selection screen.

I posted this issue on another forum too, but here is an image of what im dealing with.

Did you try the Intel driver?

That driver doesnt support windows 7 on 7th generation processors. Im basing my custom driver off of that one, but since I have to modify it to make it work with W7, it wont happily install.

Hi Smoblikat,

That screenshot tells me that Windows WILL NOT automatically install it
Within any setup a digital signature is required by default.

Your going to have DIgital enforcement set to OFF on your sysprep
bcdedit /set testsigning off

NOTE

reset it after install, via GPO

Would I be able to re-enable testsigning by putting it into my setupcomplete.cmd? Or is GPO recommended for a specific reason.

If you pause at 5:20, youll see the exact problem im having. I made a working driver for windows 7, in no way do I need any help getting the driver created or loaded. It still prompts me to see if I want to use the selected driver, im going to try and see if enabling testmode will allow it to automatically select the sustom driver to use, if that doesnt work, then this whole thing might not be possible.

Hi Smoblikat,

Sysprep not really my forte'.

just know about the driver enforcement rules.

I cannot see a reason not to reset it within the sysprep. Kari
I wonder what the guru says.

The issue is driver signing. When it's not signed, I think there's no way to make Windows to automatically pick it over a signed one and stick to it.

Theoretically, you might get lucky with a script which runs when Windows is first booted to desktop, installs the driver, and deletes itself when done. However, although this kind of scripts are easy to do, I have to admit I can't see how it could be done for this purpose, installing an unsigned driver.
