    Unable to update from 1909, error 0xc1900101


    I've been having this problem on a PC in my household for a while now, though it's gone under the radar as driver and quality updates install normally. The system now constantly says "Your system is missing important security and quality fixes" in Windows Update, but gives no option to install any. Apparently this PC has been quietly failing feature updates for several years, but it's also installing them in a very odd order. 1903 installed in 08/19, then no feature updates were attempted until 08/20 2004, 09/20 2004, 10/20 2004, and then suddenly 1909 was installed successfully in Novem

    Unable to upgrade one of the system to Windows 10 Update Error 0xC1900101 - 0x20004

    Thank you for the reply. I read both of those threads already.

    1. Resetting BIOS. I flashed BIOS to the latest version. Currently running default settings. No change.

    2. Andre da Costa brings up a list of reasons. For error 0xC1900101-0x20017 he says refer to error 0xc000021a.

    2a. Regarding his troubleshooting steps for error 0xc000021a. He says to wipe the drive and switch from NTFS to GPT. This is incorrect. If this was true, then no one could update from Windows 7 to Windows 10 without a clean install. Beyond which, I updated
    my first desktop from Windows 7 to Windows 10 when it was running Windows 7 on NTFS.

    2b. Regarding his additional troubleshooting steps for error 0xC1900101-0x20017. He has a number of suggestions, such as disabling peripherals. I tried all of these for both .iso and USB installs. No luck.

    Any other suggestions?
