Today the Windows 11 24H2 update failed with error code 0xc1900101 on an Acer Travelmate notebook and now the system is recovered to 23H1

Any suggestions how to successfully update to W11 24H2?

    Back to 23H2 maybe? I don't believe there was a 23H1 release for Windows 11. There are a lot or different TravelMate laptops, which one do you have? Your full model number is usually on the same sticker as your serial number, it should look something like TMxxx-xxx-xxxx. Did your model come with Windows 10, then update to Windows 11, or did it come with Windows 11 from the factory?

    My bad indeed it falled back to 23H2

    This is my full AcerTravel model: AcerTravelMateP6TMP614-53-TCO-75GN

    It came with Windows 11 from the factory according to update history it did install the H23H2 update successfully (september 2024)

    Hi, update BIOS with version 1.15 dated 2024/09/25 and run the Update Trouble shooter:

    and try the 24H2 upgrade again by "Check for updates", don't upgrade with a download ISO image but wait till the tailored upgrade to your system is offered by WU.
