Windows 10: I need help with the error "We couldn't complete the update. Undoing changes."

So for about a month I've been getting this error whenever I restart my computer for an specific update. I've been trying to follow this guide https://windowsreport.com/we-couldnt-complete-the-updatesundoing-changes/, and when I put system file checker in Command Prompt, it tells me that there are corrupt files and that it couldn't fix all of them.

When I try to rename the windows update folder (like the guide said) by using "rename c: windows SoftwareDistribution SoftwareDistribution.bak" it tells me that the system can't find that file.

I need some advice. I'm pretty good when it comes to computer hardware, but software is very confusing for me. I'm not entirely sure what's wrong or how to fix the problem.

Thank you in advance!

We couldn't complete the updated, undoing changes...

Hi,



I suggest you to run the Windows Update troubleshooter and check if it helps.

Windows 10 has a built-in troubleshooter to check and fix issues with Update. I would suggest you to run this troubleshooter to check if the issue is with your Windows update.

Refer these steps:

• 
  Press Windows key +X, select
  Control panel.
  
• 
  Change the view by option on the
  top right to Large icons.
  
• 
  Click on troubleshooting and click on the
  view all option on the left panel.
  
• 
  Run the Windows Update troubleshooter.
  

Keep us posted on this issue so that we can assist you better.

 

Windows 10: "We couldn't complete the updates, undoing changes"

I've got the same issue and following on @Arthur's suggestion, I had a look at my user SIDs in the registry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList and some of them belonged to users that no longer existed in the system (I had previously removed them).

I've removed the dummy entries (luckily there were only a couple) and the update worked.

PLEASE save yourself some trouble and backup the registry before trying that.
