Injecting Windows 10 1709 1803 1809 Updates into a WIM

Update 29/11/2018: This process has been tested and is working with Windows 10 1809! Your local computer must be running the same OS version as the image you are trying to DISM.

The following guide outlines how to inject Windows Updates into a WIM file using DISM. This process can help ensure newly built machines are patched before being handed out to end users. In addition this can also speed up the process of building Windows 10 as the Windows Update process during your task sequence will be relatively shortened.

• Create a WIM file directory

Md C:\wim

• Copy your original WIM to c:\wim
• Create a Mount directory

md C:\mount

• Create a temp directory

md C:\temp

•     Create a update directory

md C:\msu

• Find what index the Windows 10 Enterprise SKU is within the WIM File:

Dism /Get-ImageInfo /imagefile:C:\wim\install.wim

• Mount the WIM file using the required Index number, I am using Index 3 Windows 10 Enterprise:

Dism /Mount-Image /ImageFile:"C:\wim\install.wim" /Index:3 /MountDir:C:\mount

You will notice the mount directory has all the extracted windows files/folders

• Download the latest Windows 10 update package from Microsoft’s website and place it in the update folder C:\msu. I will be downloading the 4088776 update https://support.microsoft.com/en-us/help/4043454
• Run the below code to inject your update

Dism /Add-Package /Image:C:\mount /PackagePath:C:\MSU\windows10.0-kb4088776-x64_55756340f1e2c2090f94de6d256eafd75e1cee9c.msu /LogPath:AddPackage.log

• Lock in the Updates so they are restored during a recovery:

DISM /Cleanup-Image /Image:"C:\mount" /StartComponentCleanup /ResetBase /ScratchDir:C:\Temp

If you see the command prompt does not progress to 100%, press enter. It sometimes does not refresh although it has completed, very annoying.

• Unmount the image and commit the changes:

Dism /Unmount-Image /MountDir:"C:\mount" /Commit

• Now upload your WIM to SCCM or MDT, deploy and test.
