    Windows 11 compatible but not even offered 21H2??

    I have an HP desktop PC and a DELL laptop and both are suitable for Windows 11 although it has not been offered as yet. Both machines have received the latest Windows updates and are on Windows 10 version 21H1 build 1288.

    1. I am not interested in upgrading to Windows 11 but, if the machines are suitable for Windows 11, why aren’t my machines being offered the upgrade to version 21H2?
    2. Are there issues with 21H2 that caused Microsoft to put an upgrade block on it?
    3. I am happy with version 21H1 and I assume I will not be offered the upgrade to Windows 11 until version 21H2 is installed. Am I right in this assumption?
    Thanks.

    Stuck in Windows 10 Upgrade

    My computer seems to be stuck in a Windows 10 failed upgrade loop. I was running fine on a beta version of Windows 10, and then I came downstairs one morning to see it repeatedly booting, attempting to repair, then rebooting. The steps I've taken to diagnose are:

    • Attempting to boot off a USB drive (with all drives disabled in BIOS) - this fails at the point of the blue windows screen
    • Attempting to boot the machine itself and getting into "repair/safe mode" using F7
    • Looking at the BIOS for obvious failures (e.g. RAM that should be there is missing) - nothing obvious is wrong.

    I am fairly certain the build version was 9926. For many months, the system would attempt to upgrade, and then say "it failed" for some reason and roll back.

    Suggestions for next steps?
