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.

    You can try to update using the MCT, from Microsoft:

    1. Download the Media Creator Tool here https://www.microsoft.com/en-us/software-downlo...
    2. Open the MediaCreationTool2004 tool and Accept the License terms.
    3. Select Upgrade this PC now and make sure to select Keep personal files and apps.
    4. It might take some time to install Windows 10.
    5. Your computer will restart a few times, Make sure you don’t turn off your PC.
