    Unable to upgrade windows 10 from 1803 to 1903, always stuck at 90%

    I will try the above steps and will let you know.

    After following the steps, the update has stuck again at 90% and after an hour I turned the laptop off and rolled back to the previous version.

    SetupDiag files are here:

    SetupDiag - Google Drive

    By the way, I have also Malwarebytes Premium installed but didn't uninstall it before I attempted the update of the windows.

    update stuck at 90%

    after windows tell me to restart the computer, it gets stuck at 90% for more than 10 hours long, and I've tried to update & had this for 3 times, still not getting up to date.

    current version 1803, attempt to update to 1903.

    tried troubleshooting windows update but this happens again after it tells me to restart pc, couldn't pass this 90% process issue, always stuck at 90%, so I had no choice but to restart the computer and let it cancel itself.

    so how does this update work anyway, does it download files during the update % screen or what? it makes no sense taking that much long if it install things from hdd, if it does take more than 10 hours at least let me get some clue to estimate how much more
    longer will it take, is it cleaning up hdd space or extracting files or moving files here and there or checking something else... or is there something wrong with some files... the hdd lamp not even flashing. let me have that clue, a simple '90%' doesn't help.
