    Wait. What version is this?
    I know he didn't ask for IoT but I want that one. I want that one. There seems to be some mystics surrounding the 25h2 build. Is this official?

    Officially Windows 11 Enterprise LTSC 25H2 will never be available in any language 'coz Windows 11 (IoT) Enterprise LTSC 2024 must be 24H2.
    Can't understand why you guys try and put such efforts to get Frankenbuild...

    Not really a frankenbuild (there is no licensing pingpong or other build mixes), the 25H2 EP can be officially applied and doesn't add any new features.

    MSFT just continues the 24H2/25H2 mess and lack of information that would make all clrear.

    There is no need for installing the 25H2 EP on (IoT) Enterprise 2024 LTSC.

    Ok, let's say EP can be officially applied but can you give the warranty that Win 11 (IoT) Enterprise LTSC 25H2 would get the future updates as LTSC edition?
    I'm 100% sure that MS will say no any word on that kind of EP installation...
    IMHO, all everyone has to do is not to try installing EP manually but wait for WU to offer it...
    As far as I remember a same was happening to Win 10 LTSC 2021 during Win 10 transition from 21H2 to 22H2...
    Remember exactly that I was manually installing 22H2 EP on Win 10 LTSC 2021 but later re-installed OS, for any case.

    I heard if you can confirm that the November update that will give the new features in 25h2 and not 24h2 will not be enabled, is that true?

    LTSC is meant to never get feature upgrades or new features at all, but as said quite a few times now, nobody knows for sure till stuff happens (or not).

    Code:
    # Remove telemetry packages from the system through optional features
    Get-WindowsOptionalFeature -Online | Where-Object {$_.FeatureName -like "*Telemetry*"} | Disable-WindowsOptionalFeature -Online -NoRestart
    
    # Set registry value to disable telemetry
    reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows\DataCollection" /v AllowTelemetry /t REG_DWORD /d 0 /f
    
    # Additionally: disable telemetry services (if present)
    Stop-Service DiagTrack -Force
    Stop-Service dmwappushservice -Force
    Set-Service DiagTrack -StartupType Disabled
    Set-Service dmwappushservice -StartupType Disabled
    "Enter this in PowerShell and telemetry will be disabled."

    I don't think you can do a repair install on a 25h2 with a 24h2 ISO sir

    i just want to know if my system is broken or if we're all on the same boat. Could you try to run setup.exe from LTSC iso if you upgraded your LTSC installation with EP to 25H2? What happens?

    Do you wanna get Win 11 LTSC 24H2 back?
    Probably you should try to uninstall 25H2 EP instead if possible. Or re-install OS.
    As an option: if you have the restore points you may try to make a rollback.
    Generally speaking before to make a such kind of jumps one must make an OS backup, better with the third party apps (AOMEI Backupper, Acronis True Image, etc.).

    Is it possible to change the system language in Windows 11 without reinstalling the OS? I’m not referring to adding a language pack, but to fully switching the operating system’s language...

    Couldn't get what you meant...
    If you wanna change Display (UI) language on already installed OS, anyway you should download an appropriate langpack and switch to. After that you can remove an installed language pack(s) you don't need.
    See post: https://forums.mydigitallife.net/th...2024-24h2-26100-x.88280/page-147#post-1882739
    To uninstall language: run Powershell as admin, paste there (XX - appropriate langcode):
    Code:
    Uninstall-Language -Language XX-XX
    and hit Enter.
    P.S.: If your installed OS - original (en-us) IoT LTSC edition, as far as I know, there is no way to uninstall en-us.
    But there is a possibility to assemble a custom IoT LTSC edition ISO - via .svf file - with your desired UI language only, with no en-us.
