It always fails at exactly at "Status: Preparing to install - 80%".

I have tried everything I could possibly think of:

DISM.exe /Online /Cleanup-image /Scanhealth
sfc /scannow

Removing c:\Windows\SoftwareDistribution (https://community.spiceworks.com/topic/2223969-1809-update-error-at-install-0x80070490?page=1#entry-8486582) or "Windows Repair" (https://www.tweaking.com/content/page/windows_repair_all_in_one.html).

The WindowsUpdate.log I get with Get-WindowsUpdateLog doesn't contain anything useful either. The last messages are:

It's super frustrating. Any hope to get the update installed without reinstalling Windows?

    Try running all the steps in: support.microsoft.com/kb/971058 . Restart when done and test. – John Mar 29 '20 at 20:26
  • Try running Settings > Update & Security > Troubleshoot and click under "Get up and running" the link of "Windows Update - Resolve problems that prevent you from updating Windows". – harrymc Mar 29 '20 at 21:17

    This tool is invaluable to diagnose your problem. The error log indicates a great deal more then you realize. – Ramhound Mar 29 '20 at 21:39
  • @harrymc That was the first I tried (and did it multiple times). Everytimes says cannot find anything wrong – divB Mar 29 '20 at 21:55

    At this point, run a Windows 10 Repair Install from the Media Creation link. Use the second link, run in place, and at the appropriate point, Keep Everything. microsoft.com/en-us/software-download/windows10 .. Assuming this works (normally does) it will put you at V1909. – John Mar 29 '20 at 22:00

Since other suggestions did not work, the next step is to run a Windows 10 Repair Install from the Media Creation link. Use the second link, run in place, and at the appropriate point, Keep Everything.

Assuming this works (normally does) it will put you at V1909.
