Windows 10: "We couldn't complete the update. Undoing changes"

I bought the PC I am currently on about one and half month ago and since the 5 of June every single update has failed to install, I have no idea what to do, I've tried using Command Prompt and running sfc /scannow, it said "Windows Resource Protection found corrupt files and succesfully repaird them.

For online repairs, details are included in the CBS log file located at windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. For offline repairs, details are included in the log file provided by the /OFFLOGFILE flag.", after receiving this message I restarted my PC and the updates did not complete again, I then tried using the Windows Update Troubleshooter method which found a problem and told me to restart my PC, I did as it said and the updates didn't complete AGAIN, I re-opened both sfc /scannow and the Troubleshooter and they both did not find any problems with my computer but the updates are still not complete and every time I want to Close or Restart my PC it tries to update but fails every single time.


Please help, I wish for a swift response.

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.
