Windows 10 Feature Update 20H2 consistently fails with 0x80242016 error

I got the same error, are you able to resolve it ?

<Version>1.6.0.0</Version>

  <ProfileName>UserProfileCreationFailureDuringFinalize</ProfileName>

  <ProfileGuid>C6677BA6-2E53-4A88-B528-336D15ED1A64</ProfileGuid>

  <FailureData>Error: SetupDiag reports user profile creation failure during Finalize.Last Phase: Finalize Last Operation: Gather data, scope: EVERYTHINGError = 1009.</FailureData>

  <FailureDetails>err = 1009, LastOperation = Gather data, scope: EVERYTHING, LastPhase = Finalize</FailureDetails>

  <Remediation>Recommend you check for unused user profiles and remove any unnecessary profiles found.  Reboot and try the update again.</Remediation>

After trying all of the steps to several MS Support articles to fix the error code it still hasn’t installed - the articles suggest stopping several services and deleting the update files, it continues to have failed to install 25+ times.  Even the OS update in place attempt has not remedied the issue.  It tries every couple days...🤷��‍♂️  I’m out of ideas...

I have the same problem! And it has been bothering me for a long time from the version 1900! And the windows10 updates automatically in the background! Sometimes I clicked the restart button by mistake, ****!

I finally resolved my Windows Recovery Environment (WinRE.WIM) Issue.   My Boot Data Store was misconfigured so after a few more suggestions to fix my boot data, I was able to get the recovery environment tools working....the 20H2 update was successful.   

Yeah - almost - the 20H2 Update broke the driver for my High Definition Audio, so I have limited sound.    Now I get to find a driver and learn how to fix this issue.   OMG - it never ends with the modern tech.   

The error you found is likely the underlying issue is probably the starting place for resolve your feature update problem.   May the force be with you - or at least have better luck that I.

I have a couple posts out there and the suggestion I'm pursuing is an underlying issue I have with the Windows Recovery Environment (WinRE), which is broken.  The update seems to fail because it cannot update the BCD Directory. 

In the c:\Windows\Logs\SetupDiag folder you will find "setupdiagresults".    I believe this XML file documents the root cause of the update failure for me.   I'm following the suggestion of a community member to fix my Windows Recovery Environment which contains utilities Windows needs to update the system and in my case the Boot Code.

Additional logs are found in the $WINDOWS.~BT\Sources\Panther folder  specifically the "setupact" and "setuperr" logs.   I still haven't resolved my issue but this is the path I'm following to take corrective action.  Yours may be different.   

I'm obviously no expert....just a struggling user looking for a working feature update.   

Good luck and if you resolve let me know.

Interesting, I did find this string in the XML-file: "Error: SetupDiag reports user profile creation failure during Finalize.Last Phase: Finalize Last Operation: Gather data, scope: EVERYTHINGError = 1009"

Now I just need to figure out how to resolve THAT error.

Many thanks though!

A member of the community, Saltgrass, helped me troubleshoot my issue.  I was able to update to 20H2 successfully through his/her suggestions.

My Boot Data Store was really messed up and pointed to a bogus Windows Recovery Environment (WinRE.WIM).  I needed to get my Windows Recovery Environment working.    I followed the suggested commands to re-configure my Boot Data Store.   In my case the feature updated needed some of the utilities/tools in this special environment to complete the update.

The lesson for me was that the errors indicated by the update failure or in the update history were not really highlighting the underlying issue on my PC.  Inside the Setupdiaresults.xml file pointed to the root cause of my problem a broken recovery environment that couldn't Update my Boot Code (0x80004005).  The setuperr and setupact log files also help identify the root cause.  After resolving this issue the update took for me.

This articlemay be helpful.   I was totally over my head, but the right information to the right community member can get you going.
