I have noticed that Windows Updates for Windows 11 24H2 are no longer being installed as part of the ISO. This started happening after the August 2025 Windows update for Windows 11 24H2. I have started over with a new ISO from Microsoft, which did not seem to help. Windows updates take a long time to install, which is the reason I purchased this product.

NTLite_configuration -- This is what is on the ISO
windows_updates_live.png -- This is what is on the machine.

Please attach your NTLite preset (after removing any user passwords or license key). You might have changed something related to servicing updates.
 
OK. There's really nothing in this preset except to install updates, and remove two trivial components.

You're starting from 26100.4946 (Aug 2025), was this a previously edited image or a clean image downloaded from UUP dump?
 
I downloaded the image from Microsoft See Windows_ISO_download.

After a lot of tries (i´m working in a refurbish company as IT-Admin) i decided not to roll out an "up-to-date" Windows11 24H2. It is possible to enroll an "up-to-date" image, but it`s "old" two times per month due to new updates. I enroll a "basic 24H2" to all clients (including 9 languages). It´s much smaller, you don`t need to cleanup. And the end-user always gets the latest update by "Windows Update" without errors.
I tried to install the latest ISO (incl. latest Updates) and it was blown up about 2-3 GB. Tried to cleanup with NTlite what caused errors.
My conclusion: There`s no need to integrate updates because they blew up the image and they are always too late (cause WU is faster). Let WU do the job at the end-user.

Tested it now, worked fine here, but I think I know what it is by looking at the preset.
It's a long time dependency for Windows Update cleanliness to select DISM Update Cleanup - Compatible.

Please retry from scratch (original ISO) with that option enabled on the updates page, I'll see about setting it by default.

It's safer and faster to pre-integrate updates, especially if there is almost a month left for the next update.
No reason to put strain on the network if there are more machines at once deployed, especially since it's done while preconfiguring image anyway.
 
I am sorry I am not seeing what you are talking about. I am understanding.

Do I need to start over and reload the image. Or Can I do this on my current image?

That's the option on the screenshot.
It must be done with integration, so start again please.

Keep all settings in one preset, that way the preset is the final product, image is just temporary and needs to be newest/updated at the time of use anyway.
 
Thanks, that resolved my issue. I just tested it out, and I now have the Windows Updates as part of my image.
 
Hello,
since August 2025 we’ve been facing the issue that none of our 350 clients are able to install new updates — every update attempt fails.


Could someone please take a look and check if there’s an error in the XML configuration?

I don't see anything wrong with the preset. But you're starting from 26100.4349 (June 2025), so it's not clear if the base image was clean or already modified.
 
Hello and thanks for your reply.
I still have problems installing updates on my clients.

We use the current Microsoft images:
SW_DVD9_Win_Pro_11_24H2.2_64BIT_German_Pro_Ent_EDU_N_MLF_X23-92027
26100.2605
and
SW_DVD9_Win_Pro_11_24H2.8_64BIT_German_Pro_Ent_EDU_N_MLF_X24-07610
26100.4349

I can update both without issues using kb5063878 26100.4946 and kb5065426 26100.6584.

However, if I customize the images with NTLite (see my configuration), installing updates no longer works.

Do you have any idea what could cause this?

Best regards
 
tgail, please try without disabling the 'Internet Printing Client' in Features.

I noticed a similar error myself, was wondering if I'm testing something too specific as that must be a DISM (Windows servicing) error.
Once you confirm if that fixes it, I'll add a warning for that situation on the Apply page preview.
If you still have an error with that feature kept enabled, please attach zipped C:\Windows\Logs\CBS\CBS.log from the machine that failed the update, at that moment.

Regarding the rest of the affected machines once you have a fixed ISO:
When update issues arise due to removals, and you don't want to reinstall, best is to deploy a fixed ISO for inplace-upgrade (aka Host Refresh).

Process for mass scale:
- start with the official ISO, non-edited prior
- update with latest NTLite version, edited as you like, could be the same preset plus the changes
- put the resulting ISO/image dir on a network share
- from the affected machines run a command or a script located on the root of that image directory:
Code: 
setup.exe /Auto Upgrade /EULA accept

(note that sometimes Windows doesn't like mounted ISOs while running this, so you might need to mount a shared directory instead if you see some basic error at the beginning, like unknown command /Auto)

If you have a managed way to push the command to all target machines, even better.

Let me know how it goes.
