Issue

I downloaded the Feature Update 2004 and tried to installed it 3 times. Each time all went good without error, then it ask for restart, so I click the "Restart and Update", then it reboot (1st time) but before accessing the authentication page it reboot again (2nd time) then again before accessing the authentication page it reboot again (3rd time) this time it's really longer (as if the update was finally applying), it goes to teh authentication page. I log in, then I check and the I'm still at update 1909.

In the Windows update history I can see an error code: 0xc1900101. Nowhere else I can see an error.

The two first times I tried to update and it fails when I went in Windows Update and clicked "Check for updates" I saw the 2004 update available and was able to download and install it again. But since last try it now tells me I'm up to date yet I'm still at update 1909 and 2004 failed to apply.

PS: I have Core Protection disabled.

PS2: Windows Update troubleshooter says all is fine.

If you experience this issue on ASRock motherboard make sure that you've updated to the latest available BIOS.

Then Enter the BIOS (F2) and Turn off (Compatibility Support Module) 

After you changed the BIOS setting run Windows10Upgrade9252.exe available for download on microsoft website url: http://go.microsoft.com/fwlink/?LinkID=799445

Problem solved.

    Disabling .NET Framework 3.5 (includes .NET 2.0 and 3.0) didn't solve the update issue.

    After many tries I can't up upgrade to 20H2 either.

    My recent update history:

    Feature update to Windows 10, version 20H2

    Failed to install on ‎2021-‎02-‎10 - 0xc1900101

    Feature update to Windows 10, version 20H2 (2)
    Last failed install attempt on ‎2021-‎01-‎19 - 0xc1900101

    Feature update to Windows 10, version 20H2

    Failed to install on ‎2020-‎11-‎18 - 0x80242016

    I do not know what my problem is other than I guess it is similar. I have satellite and it is very expensive so do updates in the middle of the night during "free time" and it runs all night long (5 hours) and then during installation it gets almost finished and take everything out. I am not a high end techie so speak English if you know what I should do.

    This has happened to me 3 times. So frustrated and tired.

    I am having this same issue.  Windows 10 1909 is presently installed on a multi-OS computer.  Linux and Windows both on this computer.

    Specs:

    Biostar X370GT5 Motherboard

    AMD Ryzen 1600X CPU

    16GB DDR4 RAM (2933mhz)

    NVIDIA 1660 Ti

    And a variety of drives.  About the only thing I can think of is Windows doesn't like the EFI partition being on a different drive than Windows OS partition is on?  I dunno.  It just tried to install again today (5th try) and failed.

    This system was fresh installed with 1909, which is the version still there.  So any advice would be appreciate, short of clean installing.
