    An interesting project, ... I did everything as described in the instructions, but now what should I do with the files in the DVD folder?
    I don't see the ISO file here.…
    If you just create an ISO file from the files in the DVD folder, then the error "is that there are no necessary drivers".…
    How do I use the files in the DVD folder to make an ISO file and run it from a USB stick?
    I usually use ventoy or UltraISO or rufus.
    ***
    If I just take a new "install.vim" file from the DVD folder and copy this file to the original "Windows 11 24H2 LTSC.iso" or to the original "Windows 10 21H2 LTSC.iso " - will that be enough then?
    ***
    will this command be executed without errors?
    sfc /scannow

    I did it, of course.
    But I got the error "no necessary drivers" when I tried to install New Windows 11 from the "ventoy" flash drive..
    If I install the original Windows 11/10 then there are no errors.
    ... Perhaps I should only use the DVD drive? :eek:

    I was using Windows 11 on my computer. I'm thinking of installing my "hassle-free" Windows 10 and trying to do a new test.
    Could you give me 2-3 links to previous versions of 2xH2_Creator for Win 11?
    thanks

    Replace the install.wim from the original ISO with the modified install.wim.

    Can you explain why you want previous versions?

    Use the latest version.

    This method works, thank you! I was doing a modification of Windows 11 24H2 LTSC.
    However, if I use the original Windows 11 24H2 LTSC "as a donor", then after installing Windows, I sometimes received a message about the need to enable Defender..
    If I use the original Windows 10 21H2 LTSC "as a donor", then after installing Windows11 I did not receive any messages.
    Also, I'm a little surprised that there aren't any changes in GP.. The Update Center is also not disabled (however, it is easy to disable it via GP). . However, Defender is disabled.
    ***
    By the way, are telemetry, advertising, and spies disabled here?
    How can you compare this to the "Chinese" Windows 10 Enterprise G?
    Ja, it works well, Thank you!

    obviously not when you have a bunch of these errors

    '""C:\Users\CH\Desktop\SUN' is not recognized as an internal or external command,
    operable program or batch file.

    It appears it didnt do alot, i suggest you redo everything

    SUN LION or anyone else.that knows the answer.

    for example if this code line is already in script
    EXAMPLE
    HKEY_CURRENT_USER\Control Panel\Desktop MenuShowDelay 400 milliseconds

    but i find registry tweak that i add to script and includes the same code line but has slight chanfe like below

    HKEY_CURRENT_USER\Control Panel\Desktop MenuShowDelay 100 milliseconds

    and i want to keep the first one because i think if its already in script and i add the below it will apply last code line.

    so question is how to find all code lines that are like the above example so i can decide wich to keep.?
    i hope what i wrote makes sense. so in short how to find all code lines that are same or slight change enabled or disabled or value change so that i can delete the one i dont want to be over writed.

    @tcntad thanks yes i moved to c: and had no errors.

    My advice is to minimize optimization unless it genuinely impacts your experience. This way, you will have a clear understanding of the impact of each optimization, and the issue of inconsistent duplicate parameters will be readily resolved.

    These are my login credentials that I use without any problems on the desktop, and for the mouse, if you have duplicate code it will take that adjustment. It's best to delete it, all that's left is to do trial and error testing.
    reg add "HKCU\Control Panel\Desktop" /v MenuShowDelay /t REG_DWORD /d 50 /f
    reg add "HKCU\Control Panel\Desktop" /v AutoEndTasks /t REG_DWORD /d 1 /f
    reg add "HKCU\Control Panel\Mouse" /v MouseHoverTime /t REG_SZ /d "100" /f
    reg add "HKCU\Control Panel\Mouse" /v MouseSpeed /t REG_SZ /d "0" /f
    reg add "HKCU\Control Panel\Mouse" /v MouseThreshold1 /t REG_SZ /d "0" /f
    reg add "HKCU\Control Panel\Mouse" /v MouseThreshold2 /t REG_SZ /d "0" /f

    (OP)
    The most appropriate way is to search directly within the script using a text editor.

    For example, search for short words, like: MenuShowDelay

    You may find several codes containing MenuShowDelay, but compare them to what you want to modify.

    Change and save the script with a different name to preserve the original.


    You should also search the files below:
    - PersonalTweaks\REG\ConfigTweaks.reg
    - PersonalTweaks\Config\W112xH2.cmd and W112xH2+.cmd
    - Addons\Install\Install\Tweaks\24H2Tweaks\REGFiles\*.reg
