    Interestingly enough on my arm64 PC with clean installed W11 26H1 b28000 with installed LCU KB5079466 I can't install neither KB5079489 (ERROR_SXS_COMPONENT_STORE_CORRUPT) nor KB5083768 (0xCA00A00A).
    No idea, how to fix it.

    I haven't used windows 11 in a while now & a program I use is now moving to windows 11 only so meh.

    So, I installed the x64 version of 26h1 & it's lightning fast on my laptop.I actually like this over 24h2 ltsc iot.

    If you ask me whatever optimizations & changes, they did with 26h1 needs to be the standard going forward.

    Truthfully might make it so that my laptop remains on 26H1 until EOL as long as no issues pop up.

    Same for me, I'm going to run 28000 on my x64 PC until EOL or when/if they merge, too many problems with 24H2/25H2

    Best regards,

    I am attaching two pictures, if they can help.
    Namely, I want to put net framework 3.5 and the Microsoft activation script in the same folder and have it installed during the installation of Windows.

    What am I doing wrong, and can you help me with the script?

    @echo off
    fltmc >nul || exit /b

    call "%WinDir%\Setup\Scripts\folder\DotNet35Setup.exe" /quiet /norestart

    Call "%WinDir%\Setup\Scripts\folder\DotNet35LPSetup.exe" /quiet /norestart

    cd \
    (goto) 2>nul & (if "%~dp0"=="%SystemRoot%\Setup\Scripts\folder\" rd /s /q "%~dp0")


    Can this script be added to the script for

    @echo off
    fltmc >nul || exit /b
    call "%~dp0MAS_AIO.cmd" /HWID
    cd \
    (goto) 2>nul & (if "%~dp0"=="%SystemRoot%\Setup\Scripts\" rd /s /q "%~dp0")

    Here I use these codes inserted into setupcomplete.cmd:

    Place the files in the folder "$OEM$\$$\Setup\Programs\"

    Good luck

    The scripts don't work, is there a possibility for integration, so that it is already installed as soon as it enters the desktop?

    Is there any new baseline .1761 in 26H1 arm64?
    With Insider ISO .1 I can't install KB5083768, because updater wants files (wmploc.dll.mui, wmpnetwk.exe.mui) from .1761 and I have (in WinSxS) files from RTM .1 + files from installed KB5079466 .1719.
    How can get .1761 files, when they are not neither in ISO nor in any KB ?

    Code:
    Error                 SXS    Could not acquire content to get file 'wmploc.DLL.mui' in Microsoft-Windows-MediaPlayer-Core.Resources, version 10.0.28000.1761, arch arm64, culture en-US: CBS_E_PAYLOAD_FILE_MISSING
    Error                 SXS    Could not acquire content to get file 'wmpnetwk.exe.mui' in Microsoft-Windows-WMPNSS-Service.Resources, version 10.0.28000.1761, arch arm64, culture en-US: CBS_E_PAYLOAD_FILE_MISSING
    
    Edit:
    We have solved it. OS has 2 LPs installed (ISO was cs-CZ originally and en-US LP was installed manually).
    However Windows Media Player FoD was installed before en-US LP, so these capabilities were missing:

    Microsoft-Windows-MediaPlayer-Package~31bf3856ad364e35~arm64~en-us~.cab
    Microsoft-Windows-MediaPlayer-Package~31bf3856ad364e35~arm64.x86~en-us~.cab

    Hello, what is your 'base' language?
    I did encounter error while performing UUP conversion from 28000.1 to 28000.1764 with base language en-GB and (additional language through FoD), id-ID and zh-CN.
    The problem is missing Windows Media Player FoD in zh-CN.
    How specific is that :confused:
    I did not get this error on earlier builds.

    Yours may be missing Windows Media Player FoD in en-US.

    Another anecdote is a desktop PC of mine with build 28000.1719.
    It refused to update to 28000.1764 and 28000.1836.
    I manually add Windows Media Player FoD in id-ID and zh-CN.
    Only then I can update the PC.

    Yes, it it EXACTLY that.
    Base language cs-CZ + LP: en-US installed from UUP ESD.
    WMP FoD LPs were missing (arm64 + x32).
    THANKS for the confirmation.
