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.
