    When upgrading Windows you can skip versions / builds.

    Upgrades can be performed with the upgrade assistant or with a Windows 10 iso.


    When troubleshooting Windows 10 iso offer more flexibility.

    Before upgrading steps can be made to increase the likelihood of success:

    1) uninstall any non-Microsoft:
    a) antivirus software
    b) firewall software
    c) drive encryption software

    2) update drivers

    3) update BIOS

    4) remove non-essential hardware

    5) verify that the drive has > 30 GB free space


    If there is a failure then run setupdiag for troubleshooting:

    I would suggest making a full backup of your first with Macrium Reflect as there's no guarantee you won't have problems.

    I would also make bootable USB using Media Creation Tool from the link you posted, then you can boot from it or just run setup from it to start the Windows 10 2004 installation process.

    It's time consuming to look for the "why".

    Attempt the upgrade and troubleshoot if it fails.

    These are links for 2004:

    That's a FAQ. Most probable:
    a. MS has blocked it because of a possible compatibility issue with your PC/PC configuration
    or
    b. Builds are rolled out progressively over months, prioritising those deemed most compatible

    If (a) my understanding is (and this is only what I've heard) that for current builds, even downloading and using an iso file will not bypass the compatibility check. (There is the question of whether that applies if you are not online when attempting the upgrade).

    As @zbook says, you can't find out definitively - although perhaps a failure to upgrade using an iso file might tell you there is an incompatibility, but not what it is.

    thanks @zbook @steve108 @dalchina for your quick answers

    dalchina said:
    b. Builds are rolled out progressively over months, prioritising those deemed most compatible
    microsoft says
    (Note: You may not see Download and install on your device as we are slowly throttling up this availability over the coming weeks, or your device might have a compatibility issue for which a safeguard hold is in place until we are confident that you will have a good update experience.)
    i looked answers.microsoft both Turkish and English versions
    that i understand microsoft blocked it for compatibility issue that you mention

    but it also says you can use the assistant for upgrade
    but we do not know if it fails or not

    so there are still 2 options for me
    a. waiting for weeks and months (already passed 5 months) to ms open on windows update service
    b. trying to upgrade from assistant or using iso

    for 2nd option i need to backup my hdd,
    making live disk for 1909 version
    making live disk for 2004 upgrade

    my system is stable on 1909 version, using it without any problems, i think i am going to wait for a while
    if i have a free time i will do the 2nd option
