    Why is it not updating, what does the Registry Tweak Tool have to do with it? It is not what you delete that is important, but what you delete with this program. I work with OS 26200.5622 and the update to version 26200.5641 came through the Update Center without any questions.

    Here, an update to version 26200.5651 has appeared on the network. I don't install it manually on principle, I'll wait until it arrives from the Update Center...

    Yes, there is some problem with downloading from this file hosting service today. Let's wait, maybe they will fix it?

    Message from file sharing service: We’re sorry, this error has been recorded.
    Please retry your download later.

    I don't even know what to tell you about this? Personally, tweaker.exe deletes everything I need and it doesn't affect further system updates. Sorry ...

    Alright, this is the script. I hope it can offer something useful.
    mediafire.com/file/gfv3d0o2zozzyxe/10_5_250610.zip/file

    Sorry I have not put any comments but here is a short explanation
    - win10.txt is the main script for windows 10 21h2 ltsc x64
    - download the updates from downloads.txt and copy them in the updates folder
    - mount the original windows iso and set the drive letter in the script variable DVD (DVD=F: for example)
    - rename win10.txt to bat or cmd
    - start a command prompt as TI from PowerRun and run the script

    Then the script does the following
    - copies wim image and mounts it
    - installs the specific updates
    - removes the packages listed in remove.txt
    - adds the registry tweeks from registry.txt
    - deletes recovery image, edge setup and other files
    - prepares dvd directories for uefi boot only
    - saves the image and creates iso

    I prefer to keep it simple and compact because I only have basic scripting skills. As you can see it does not do any error checking so it will not stop if something is wrong.
    Some choices were made to keep low space when running so that it can put on a ramdisk (20gb ramdrive is enough). In the future I want to remove more packages but I don't mind so much with the final size since ltsc is already very small.

    Mediafare has a loading failure and gives an error: "generating new download key". This means the file is corrupted. You need to re-upload.

    I'm trying to learn how to edit the .mum files to remove the junk.

    But while I don't know how to do that, we're trying other ways to clean up.

    Maybe the Registry Tweak Tool will break updates if it removes something that shouldn't be removed. Just a thought...

    Maybe you can help us with editing the .mum files?

    I'd really appreciate it!

    Editing .mum files for every cu is to much work imho.

    i think it would be best to build a script to remove all the junk you can, without the need to edit cu files, imho.

    It's true. Editing mum is a lot of work.

    Let's continue with our removals then...

    Thanks.

    By the way, see the attached image, from Windows Update of an image in which we used the package removal with Registry Tweak Tool.

    Windows Update works without errors.

    The script had updated the image to date (26100.4349) before many packages were removed. This is why, after installation, Windows Update won't push CU ATM.

    Q: What about upcoming CU, e.g. 26100.4351 (KB5063060)?
    A:
    Code:
    C:\windows\system32>dism /english /image:K: /add-package:z:\Windows11.0-KB5063060-x64.msu
    
    Deployment Image Servicing and Management tool
    Version: 10.0.19041.844
    
    Image Version: 10.0.26100.4349
    
    Processing 1 of 1 -
    [==========================100.0%==========================]
    [===========================73.0%==========                ] z:\Windows11.0-KB5063060-x64.msu: An error occurred applying the Unattend.xml file from the .msu package.
    For more information, review the log file.
     Error: 0x80073712
    
    Error: 14098
    
    The component store has been corrupted.
    
    The DISM log file can be found at C:\windows\Logs\DISM\dism.log
    
    C:\windows\system32>
    
    --->
    The component store has been corrupted.

    Corrupted = Unrecoverably damaged.

    [Rule of latest Update Format]
    Except Custom Update, CU will fail when any System package had been modified or removed.

    Please, in your opinion, would it be possible to remove the garbage before integrating the LCU? Could this work?

    What is the best way to remove all the garbage?
