Error 0x800f0922 for 2020-01 Cumulative Update for Windows 10 Version 1909 for x64-based Systems (KB4532695)

Install attempt fails with error 0x800f0922 whether I run Windows Update  to install this update or run windows10.0-kb4532695-x64_a85fd28af075ebfd8b0753d2c2aca244e926c3ce.msu

Running WIndows 10 Pro Ver. 1909 build 18363.592

I have tried every suggestion by HiltonOishi in https://answers.microsoft.com/en-us/windows/forum/all/failed-install-attempt-error-code-0x800f0922/c5eb31d7-f04f-4ff8-9d6f-f39e4f03944b

After the update installs I restart the computer and when it reboots it gets to 93% in "Working on Updates" then I get "We couldn't complete the updates Undoing changes"

Windows Update says this is an optional update. Should I just ignore the problem till the next update?

    If your version is 1909, why not upgrade to 20H2...?...

    (a) Make a Windows system image backup of 1909. It will give you a 2nd route back, if the upgrade will fail. Want instructions?

    (b) Make a 20H2 Installation USB drive here...

    https://www.microsoft.com/en-us/software-download/windows10

    Download Windows 10 -- always the latest version (currently 20H2)

    Instructions are at the site how to use it to do an upgrade. Basically, you boot to Windows, plug in the Installation USB drive, open it in File Explorer, & click Setup.exe. it will have undo capability (if necessary), but it only lasts 10 days. So, the image backup is important.

    Thanks for the suggestion. I tried to manually update to 2004 AND 20H2. Both failed with different error codes.

    But I will try again tonight and see what happens. Fingers crossed.

    You are welcome. If the upgrade fails, there will be logs to look at. In particular, I'd like to see the results of SetupDiag...

    https://docs.microsoft.com/en-us/windows/deployment/upgrade/setupdiag

    SetupDiag

    It looks like it runs automatically now when necessary. Show us the file it produces, if you can find it per instructions in that article.

    From your SetupDiagResults.log...

    "

    RegisteredAV = Norton Security             <<<Norton is installed

    Error = 0xC1900101-0x40017                 <<<Error message

    "

    https://docs.microsoft.com/en-us/windows/deployment/upgrade/resolution-procedures

    Resolution Procedures

    "

    0xC1900101 - 0x40017 Clean boot into Windows, and then attempt the upgrade to Windows 10. For more information, see How to perform a clean boot in Windows. <br><br>  <br><br>Ensure that you select the option to "Download and install updates (recommended)." Also be sure to remove unsigned drivers. Windows 10 upgrade failed after the second reboot. <br><br>This is usually caused by a faulty driver. For example: antivirus filter drivers or encryption drivers.

    "

    I suggest you uninstall Norton. Windows Defender is integrated into Windows & updates itself frequently. Windows has other defenses as well. Then, do the clean boot, & try again. Post SetupDiagResults.log again, if it still fails.
