    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?
