Windows doesn't update, halfway through goes to a black screen that says 'Undoing Changes Made To Your Computer'

Hi Jay. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Moderator. If you will work with me I will be here to help until the issue is resolved.

The WIndows Upgrade assistant is buggy. I would manually upgrade to the latest version 1909 by opening the Media Creation Tool from this link: http://windows.microsoft.com/en-us/windows-10/m..., choose Download Tool Now, then open the tool and choose Upgrade This PC Now. This saves your files, apps and most settings in place, is the most stable method to change versions, brings your Updates current, resolves most problems.

If any problems report back the verbatim error and number, then continue with these steps for overcoming Version Upgrade problems: http://answers.microsoft.com/en-us/windows/wiki...

If the Version has problems I will work with you to try to resolve them. If the problems are unfixable for now, you have ten days to roll it back in Recovery settings. You can then hide it so it doesn't try to reinstall following this same method: https://www.howtogeek.com/223864/how-to-uninsta...

Most problems are resolved by doing this gold standard Clean Install which should get you past all difficulties as it has millions of others who have followed the steps in this link and never come back to report another problem: http://answers.microsoft.com/en-us/windows/wiki... . So read it over and see if its something you want to learn to do.

I hope this helps. Feel free to ask back any questions and keep me posted. If you will wait to rate my post, I will keep working with you until it's resolved.

Hi Greg,

I tried the first step that was mentioned and tried using the Media Creation Tool. However the result was the same. at 94% it restarted and got the black screen again with the message 'Undoing Changes Made To Your Computer'.
The error code I got was  0x8007042B - 0x4001E (Image attached)

There are some things you could try to get more information on the problem.  The first is to download and run the setupdiag.exe utility from the first linked site.

If that doesn't show a cause, and disregard the can't find known problem phrase and copy and paste the listing..

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

If that isn't enough, we may need the files, setuperr.log and setupact.log, located in the C:\$Windows.~BT\Sources\Panther folder.  If you could make those available on your OneDrive or some other file sharing site..

Proceed with the tutorial I gave you the compiles everything possible for Overcoming Version Upgrade Failures: http://answers.microsoft.com/en-us/windows/wiki...

One of those steps should always work. If not you will know for sure the install or account is too corrupted to Upgrade and can do the vastly superior Clean Install which will put you beyond having these problems in the future as it has done for millions of others.

Greg oversteps in his last post, it may be something very simple, such as a corrupted file..  But of course, the option to do a clean install was there before it was suggested by a second party.. 

But I cannot guarantee information in the logs will lead to a solution..

Hi Saltgrass

I tried your method, the command promt didnt display anything it just finished running. I have the 2 log files here anyway.

Hi Greg,

I tried pretty much everything except a clean install. I updated drivers, BIOS and did a system scan, which came out fine.

I uninstalled the third party virus guard and installed Malwarebytes and did a full scan as well. No virus was detected. I stopped all the services except the Microsoft services and disabled all the apps on the startup. But still the upgrade stops at around 92% installation and undo the changes made.

I made a system backup on an external device and also created a restore point. If there is no other option, I could do a clean install, but I do not want my other two partitions to be wiped. If it is only the C: partition that Windows is installed on, that is formatted. I can go for it. 

I just got your files but notice the following.  I will be checking to larger log tomorrow to see if I can find anything else..

Error                 MIG    Error 2147946848 while gathering object C:\Users\Jay\AppData\Local\Packages\Microsoft.MicrosoftSudoku_8wekyb3d8bbwe\AC\Microsoft\CLR_v4.0_32\NativeImages\Temp\2090-0 [Arkadium.WindowsStoreModule.dll]. Shell application requested abort![gle=0x00001160]

Hi Saltgrass...

I have no idea what that is, but looks like it's got something to do with Sudoku I installed few years ago from the Windows store. Let me know what to do about that. I uninstalled that, since I dont play that anymore.

You have already installed the app?

Can you tell if the Arkadium.WindowsStoreModule.dll file is still in the location mentioned?

If it was a partial uninstall, you may need to reinstall it so you can uninstall it or at lease update it.

I just installed it, although I don't have an xBox, and I did not get the \NativeImages folder.  So you might be able to delete that folder or the temp folder ..
