    Thanks for your contribution!

    I believe it's possible to do this through a script.

    I'll try to write the code for this, including two options:

    1 - Add setupcomplete.cmd directly to the mounted install.wim;

    or

    2 - Add setupcomplete.cmd to the $OEM$ folder, as we're currently doing.

    Therefore, I believe two setupcomplete options would be necessary, one for HWID and one for TsForge.

    Give me some time and we'll see...

    Cheers!

    I downloaded it, there is a “Readme” file from
    sainfo
    with content:
    Code:
    User instructions:
    
    1. Download the “24H2_GamerOS” archive and unzip it to any partition
    2. Move your Windows 11 IoT Enterprise LTSC [26100.1742] install.wim file to the “Wim” folder in the localization you need
    3. Place the necessary .reg and .cmd scripts in the “Data\PersonalTweaks” folder.
    4. Place the necessary cumulative updates in the “Data\UUP” folder.
    5. Run the “Runme.cmd” file as an administrator.
    6. The install.wim file is processed by the script and then moved to the “DVD\sources” folder
    7. The $OEM$ folder will contain everything you need to install and activate your OS
    
    Note: after processing the install.wim image with the script, process it with the NTLite program (the .xml file is located in the Data\Presets_NTLite folder). The final, clean configuration of the image is performed in the DISM++ program. After the final configuration of the image in the same program, convert the install.wim image to the install.esd format. Next, in the DVD\sources folder, replace the install.wim image with the resulting install.esd. Use the DVD at your discretion. The answer file (in my case) is located in the boot.wim file. The logfiles.txt file is located in the Data\logfiles.txt folder.
    
    Good luck!
    Hmm, what is a 24H2_GamerOS?

    Interesting case. Once again read my text. We look for the familiar letters and see: I decided to share with you what I got on the basis of an excellent script from SunLion. And what's not clear?

    Everything is in your hands, what you choose in the settings you will get in the output.

    Good luck!

    (OP)
    ==================
    2xH2_Creator_14.1
    ==================

    Updated to 26x00.6584

    - Modified the $OEM$ folder and the script copy. Now the activation scripts are copied to the install.wim
    and the other apps/tools are kept in the $OEM$ folder.
    This way, those who want to use multiple indexes to create an AIO version will already have the scripts inside the install.wim
    for each index (suggestion from @KleineZiege)
    - When it is image 25H2_LTSC, TsForge will be used and in the other options the HWID

    - Updated defender-dism-x64.cab (release 2025.09.16)
    - Added option to create 24H2 or 25H2 image
    - In this format, all questions will be presented for choice.
    - The all.txt file was updated
    - Several small adjustments


    Test with:
    - pt-br_windows_11_enterprise_ltsc_2024_x64_dvd_2bb6b75b_2.iso
    - pt-br_windows_11_business_editions_version_24h2_x64_dvd_ecc90645.iso

    No, I am not stealing anything from anyone, and especially not attributing anyone else's merits to myself. I just offer my own, different approach to the formation of the structure of the tool. In my opinion, it is more optimal and more convenient for the end user. It is up to you to use it or not.

    Tested script no errors, ran in a vm, small gripe I enabled search though in taskbar settings was disabled by default, easy fix to manually toggle it back on.

    Some laptops have activation in BIOS.
    Wouldn't activating from "install.wim" be a problem for them?

    I don't think there will be any problems, because the codes in the $OEM$ folder are copied to the same location as in install.wim, i.e. .\Windows\Setup\Scripts.

    So everything should work normally.

    Great Job @SunLion
    I'm testing tonight. Can anyone tell me whether the flags are set with the script in IOTEternerprise?
    Or does it remain on EnterpriseS?

    The script doesn't change this. It remains EnterpriseS or IoTEnterpriseS depending on the image you're editing.

    Everything worked except for LTSC 2025. It is installed as LTSC 2025, but activation does not take place with the original script from Tsforge. I'm now using my modified Setupcomplete.cmd.
    The first installation is online, the second offline. Let's see how it behaves.
    Otherwise, I'll build two activations into LTSC 2025.
    Namely, KMS4k.
    By the way, I haven't reduced the size of Pro and Enterprise yet. These are original files from MVS that I've tweaked a little, Reg Keys, etc..

    I'll add two more indexes,
    Server 2025 Desktop view.
    # The result is coming soon
