Using the Dell Driver Pack

Slipstreaming the Dell Driver Pack into Windows 11 Installation Media

Dell provide a Driver Pack for Dell Business Models. This driver pack can optionally be slipstreamed into the install.wim which will result in Windows 11 having preinstalled Dell System Drivers. This is only required if your hardware is bleeding edge and Microsoft don't have basic Device Drivers included already in the Operating System (which is very rare nowadays) and only recommended if you want to save time when deploying a Windows 11 Image to a fleet of Matching Computers found for example in a school library or office.

Windows 11 ISO

You will need a Windows 11 ISO:

Mounting the ISO

Right click the ISO and select Mount to Mount it as a Virtual Drive that can be explored within Windows Explorer:

Go to the sources folder:

Look at the install.wim:

The install.wim

Copy the install.wim from the mounted ISO directly to the C:\ Drive and select Continue when prompted:

Then right click the install.wim and select properties:

Ensure that "Read Only" is unchecked:

Dell Driver Pack

If using a Dell Business Model such as an XPS, Precision, Latitude or OptiPlex, your system model likely has a driver pack. We can optionally slipstream this driver pack into the install.wim so your installation media has all the drivers required for your system incorporated within it:

We will need 7zip to extract the driver pack to a folder for the slipstream:

Extracting the Dell Driver Pack

Double click the 7zip setup and select install:

7zip will now be installed:

Right click the driver cab file and select Show More Options:

Then select 7-Zip then Extract to " ":

You can ignore the warning and select Close:

In the extracted folder you should find an x64 subfolder:

Right click it and rename it Drivers and copy it to the C:\ Drive:

Slipstreaming the Dell Driver Pack

Now right click the Windows Start Button to access the Windows Power Users Menu and select Windows Terminal (Admin):

Accept the User Account Control:

Check Index of Edition

Copy and paste the following line of code:

Dism /Get-WimInfo /WimFile:C:\install.wim

In my case I am interested in Windows 11 Pro which in the case of the Unofficial Windows 11 Insider Preview UUP Dump ISO has Index 3 (it has an Index of 6 in the Official Microsoft Windows 11 Insider Preview ISO):

Create WinTemp Folder

Next I want to create a new temporary folder which we will use to extract the install.wim to and then add the driver pack to:

mkdir C:\WinTemp

Mount Wim to WinTemp Folder

Use the following command to extract your install.wim to this temporary folder:

Dism /Mount-WIM /WimFile:C:\install.wim /index:3 /MountDir:C:\WinTemp

Note amend the command for your desired index.

The Windows setup files will now be extracted to the WinTemp folder:

Add Driver Pack to WinTemp Folder

Now we can add the driver pack using:

Dism /Image:C:\WinTemp /Add-Driver /Driver:C:\Drivers /Recurse

You will be informed that all the drivers are successfully added:

Commit Changes and Unmount

Now we can unmount the selected index of the install.wim and commit the changes which will repackage the index into the install.wim file:

Dism /Unmount-WIM /MountDir:C:\WinTemp /Commit

Remove WinTemp Folder

We can now remove our WinTemp folder (which will be empty again):

rmdir C:\WinTemp

Check Updated Details

We can then look at the updated details:

Dism /Get-WimInfo /WimFile:C:\install.wim

Use the updated install.wim in place of the install.wim found in the sources folder of the INSTALL Partition of your USB Flash Drive.
