  1. Windows 11 upgrade error code 0xa0000400


    It's been a while since I'm trying to install windows 11 on my pc. I tried many times, waiting a few weeks after each tries, thinking I was maybe just too impatient to get windows 11, however, it still doesn't work...I have the dell latitude 3510. I got it thanks to school so the windows version is windows 10 professional education. I did the pc health check and it fits the requirements i even have the notify in update settings!.I already searched many times on the internet but can't find any solution for the error code 0xa0000400. Does anyone know what is the problem hidden behind this code

    :)

    Windows 11 upgrade error code 0xa0000400

    Windows 10 version 2004 upgrade fails with error 0xA0000400

    On (only) one of my home systems, attempting to upgrade to version 2004 (using the Upgrade tool Windows10Upgrade9252.exe) fails (after reporting CPU, memory, and disk space are OK) with error 0xA0000400.

    This error code doesn't seem to be documented anywhere.

    Any clue?
