Win10 1607 LTSB not finding drivers

[lukebarone]

I created an image based on the LTSB 1607 Windows 10. I can deploy it fine to the first of a fleet of new machines - Dell Latitude 5590’s.

I have the fog.drivers script running after imaging, and the C:\Drivers folder is populated, so I know FOG is copying the drivers.

However, Windows is not looking in that folder during the first boot up, and installing the drivers it needs.

unattend.xml (the part that mentions the Driver path):

...
    <settings pass="offlineServicing">
        <component name="Microsoft-Windows-PnpCustomizationsNonWinPE" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
            <DriverPaths>
                <PathAndCredentials wcm:action="add" wcm:keyValue="1">
                    <Path>C:\Drivers</Path>
                </PathAndCredentials>
            </DriverPaths>
        </component>
    </settings>
...

The tree of files created (trimmed):

C:\
  Drivers\
    x64\
      audio\
      chipset\
...
      storage\
      video\

fog.drivers Script:

#!/bin/bash
ceol=`tput el`;
manu=`dmidecode -s system-manufacturer`;
case $manu in
    [Ll][Ee][Nn][Oo][Vv][Oo])
        machine=$(dmidecode -s system-version)
        ;;
    *[Dd][Ee][Ll][Ll]*)
        machine=$(dmidecode -s system-product-name) #pruduct is typo, just realized sorry :(
        ;;

#this next bit adds driver location on pc to devicepath in registry (so sysprep uses it to reference)
# remember to make devicepath= match the path you've used locally
#also do not remove %SystemRoot%\inf
#and to add more locations just use ; in between each location

$devpath

EOFREG
echo -e "\b\b\b\b\b\b\b\b\b\b\b${ceol}Done"; # this just removes "In Progress and replaces it with done :-)"

What can I do to get my new images to detect the drivers, and automatically install them correctly?

That’s interesting, I would have though 1607 still worked. If you look at this post: https://forums.fogproject.org/topic/11126/using-fog-postinstall-scripts-for-windows-driver-injection-2017-ed/4 You will see that 1703 no longer works with the unattend.xml settings so you need to add the following to the setupcomplete.cmd file.

pnputil.exe /add-driver "C:\Drivers\*.inf" /subdirs /install
pnputil.exe /add-driver "C:\Drivers\*.inf" /subdirs /install

Calling the pnputil command twice should be sufficient to find all of the hardware. I don’t know why MS moved away from the unattend.xml file pointing to the drivers. I’m sure there was a good reason.

@george1421 OK, I’m re-capturing my image, and then I’ll deploy it. I added the commands for PNPUTIL before turning on the Fog Service, as I know it took quite a while to run after I logged in. I’ll report back once I know whether or not this works.

This worked! Thanks!

I’m disappointed Microsoft’s method doesn’t work anymore, it was super helpful when we were testing Windows 10 at my previous site…
