    26H1_Creator_1.9
    =========================
    Updated to 28000.2179


    - Due to the adoption of PowerRun to run the script in TrustedInstaller mode, please note the recommendation below:
    1 - The first time you run the 2xH2_Creator_16.x_Start.cmd script, a PowerRun warning will appear, asking you to enable command line commands.
    2 - To do this, go to the tools folder and run the PowerRun_x64.exe file.
    3 - In the window that opens, go to the Files tab and click "Allow command line" and Close the PowerRun_x64.exe.
    4 - That's it. Now everything will run without problems.
    Note: This was tested on a Windows 11 host system and everything went smoothly, without errors, and the log file was created automatically.

    - The MAS\TsForge package is used as the default.

    - To give users the option to install or not install certain applications, Windows Post Install (WPI) has been added.
    - It will be the last process to run after the Windows installation.
    - To use it, observe the following:
    1 - Leave the applications you want to install selected.
    2 - Uncheck those you do not want to install.
    3 - To install, click the "Start installation" icon in the upper left corner. Wait for completion.
    4 - The system will restart at the end.
    NOTE: If you do not want to install any applications, click the "Exit" button in the lower right corner to close WPI.

    - Updated all.txt
    - Other minor adjustments

    Hello everyone,

    I am currently using a slimmed-down Windows 11 LTSC version, and it seems to come with “Sunlight” branding. Every time I boot the PC, the system shows “Sunlion”, and there also appears to be a user profile or folder with that name.

    I would like to know if there is any way to remove this branding completely and set up the system with my own personal profile instead.

    What I would like to achieve is:

    • no “Sunlion” branding during boot or login
    • no default user account named “Sunlion”
    • no C:\Users\Sunlion profile folder
    • a clean user profile with my own name
    • a system that looks neutral and professional enough for work use
    I am not just looking to rename the visible account name. Ideally, I would like to remove or replace the underlying profile properly, so that Windows does not keep using “Sunlion” internally.

    Does anyone know if there is a proper way to do this? Maybe a tutorial, guide, or recommended method for removing this kind of preconfigured branding and creating a clean user profile from scratch?

    Any help would be appreciated.

    Thank you!

    If you used the autounattend.xml you need to either remove this or edit this with your details.

    Check that you are not using the Autounattend.xml file from the Windows 10 version. In that version, the Autounattend.xml file comes with the nickname SunLion and must be edited to your nickname and timezone.

    Use the Autounattend.xml file from the Windows 11 version, which prompts you to enter your username and password during installation.

    This almost tempts me enough to try Windows 11 LTSC IoT on one of my daily driver PCs (again)... Are you running Windows 11 on bare metal (industry jargon for not in a VM) on any of your daily driver machines SunLion?

    No, I still prefer to stick with Windows 10 Enterprise LTSC.

    Windows 11 still has a lot of things to fix...
