Windows 10: Feature Update to Windows 10, version 20H2 failed

I have been trying to install an update through the Windows update client. When I restart or shut down and install the update, it gets 7% complete before failing. I get the message that windows was unable to complete the update and it is undoing the changes. After restarting and getting back to my desktop, opening Windows Update tells me there was an error encountered and to try again later. The event log gives me error code 0x80070490. This has been going on for several months now, and I have tried to install the update dozens of times. I have run both the SFC scan and DISM scan, and those did not let me install the update successfully. I have just noticed in the update history, it seems like it is saying the update has both successfully installed and failed to install, which doesn't make much sense to me. See screenshot below. Is there anything I can do short of completely reinstalling Windows? I still have my installation disc from when I built this computer.

feature update to windows 10 version 20H2 error 0xc1900101

Dear community,

I am getting the 0xc1900101 error for a few month already when trying to update my Windows 10.

I tried with the latest feature update to windows 10 version 20H2 today and the problem still remains.

I tried a lot of solutions found on the internet to solve this issue, but none of them worked:

At about 60% of the update, it fails, and Windows rolls back to its previous version.

Any tip on how to get more insight about this error and find a way on how to fix it would be greatly appreciated.

 

Update History is not showing v.20H2

Hi Dominic

I am Dave, an Independent Advisor, I will help you with this . . .

This is normal behavior in Windows 10, typically when you install a Feature Update like 20h2, the update history is wiped, this is to prevent the user from trying to uninstall an update that was prior to the Feature Update, which would de-stabilize Windows
10, the list should start building again, when some updates are applied to version 20h2 . . .
