KUCHow to integrate updates into a DVD image
using KUC


1.      Locate your wim file
set sourcefile=d:\Win7DVD\sources\install.wim

2.      Create a temporary folder
md c:\offline
set tmpdir=c:\offline

3.      Mount the %1 image of the wim file
dism /mount-wim /wimfile:%sourcefile% /index:%1 /mountdir:%tmpdir%




You can use the statements above to create a mountwim.cmd commandlet. If you run, for example,


Mountwim.cmd 3

the third image of the wim file will be mounted.


After you have mounted the image you need, run KUC


KUC /DVD-image-dir:c:\offline /up-dir:c:\wu /repo-dir:c:\wu\repo


Select the options you want and finish KUC.

In the c:\wu folder first run


It’s extremely important, that you remove all old packages before you add new ones. During DVD update integration, it’s not possible to remove some kinds of “superseded” packages. That means, if you want to integrate IE9, you first have to remove all IE8 packages to have a clean DVD (Nevertheless, you can leave them on the DVD (recommended)). After adding IE9 to the DVD, it’s not possible to remove all IE8 packages from the image.

In addition, if your DVD has version 1 of a package installed and you want to install version 2, you need to remove version 1 before you add version 2. If you don’t, the removal of version 1 will fail.

KUC takes care of that. It will not offer the addition of version 2 as long as version 1 is installed.
If both version 1 and version 2 are installed, KUC will remove both of them first before version 2 is added.

Furthermore, I noticed that there are several updates that only can be removed if other updates are removed first. Most of them are windows-win32k updates.
The same principle applies during installation of updates: some packages only can be installed if other updates are installed first.
Fortunately, most of them are KB9xxxxx normal updates (non LDR), which are installed first. 


You may have to run the remover more than one time.


It’s up to you, if you just run the remove_old command again or create a new fresh one with KUC after the first run finishes (recommended).


Now that we have all old packages removed, we can start the updates process.

While running KUC, you downloaded all missing updates, which are now located in the c:\wu\repo folder.
In the next step, we populate the working folders with the updates. Just run




Before you continue with the update process, this may be a good point to decide if you want to install additional languages.
Finally, we start the update process.




After the update finishes, rerun KUC to check if there are any updates/features you missed or could only be installed if others had been installed first.
If all is satisfactory, only one thing is left to do. To save the changes to the DVD image, run


dism /unmount-wim /mountdir:%tmpdir% /commit


If something goes wrong during the process, you can run the dism command with the /discard switch (instead of /commit). This will leave your source image in its initial state.

Do not forget to re-enable your anti-virus software if you turned it off.


Useful Notes:

You cannot modify the DVD directly. You have to copy its content to the hard disk.

Do not try to add IE9 languages packs of a language that is not supported by the installed OS languages!

Dism will start the installation and result in Error: 0x800f0830: “The specified image is no longer serviceable.”

The only thing you can do is to unmount the wim with the /discard switch.
Mounting and dismounting an image is a hard disk intensive process. So exclude the c:\offline and the d:\Win7DVD\sources folders from virus scanning. You should exclude .wim files from scanning too. Disabling the virus scanner is a possibility but not necessary.
Sometimes the mounting of an image fails. Try “
dism/cleanup-wim” and / or delete the temporary folder c:\offline and recreate it.

If you have any problem with installation or removal of a package, look inside the “packages_out.txt” file of KUC. There you may find the reason.

If you want all 5(x64) or 6(x86) images inside a wim to be updated, you have to run the process for each image.

Here is an overview of the images located in the
x64 win7 DVD: 1=Home Basic, 2=Home Premium, 3=Professional, 4=Ultimate.

x86 win7 DVD: 1=Starter, 2=Home Basic, 3=Home Premium, 4=Professional, 5=Ultimate.

To identify the wim images, run dism /get-wiminfo /wimfile:%sourcefile%


After all images are updated, you will notice that the new wim file is much larger than the original one. To shrink its size, run

imagex /export /check /compress fast d:\Win7DVD\sources\install.wim * d:\Win7DVD\sources\newinstall.wim

delete d:\Win7DVD\sources\install.wim

rename d:\Win7DVD\sources\newinstall.wim d:\Win7DVD\sources\install.wim

You could use the
/compress maximum instead, but that normally takes a long time. Also, depending on the speed and the memory of the destination computer, the installation process takes longer. (All that is compressed must be uncompressed. If you use high compression methods, uncompressing could take a long time). The opposite switch is /compress none. That’s the fastest way. I think the default is /compress fast.


Creating the ISO:

oscdimg /b"d:\boot\etfsboot.com" /h /lWin7 /u2 /o d:\ c:\wu\w7x64.iso

One bad thing to say: To create the references for KUC, me myself I cannot use KUC.

After you have updated only one image, you can imagine how much time it takes to keep all the KUC references up to date.
