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.

 

Update KB4550961 couldn´t be installed

Hi! I´ve tried hard to install KB 4550961 unsuccessfully. Even run this or that in order to correct whatever the problem might be.

However, after restart it appears “Updates couldn’t be installed” on the screen. Running Scannow and Restorehealth as Administrator didn´t
work either.

I´ve also gone step by step thru “Fix Windows Update errors” steps 1 to 5. I´m reluctant to follow Step 6 Reset or Reinstall Windows –
Refresh is not included - because I´m afraid I might loss some stuff important, though I created a restoration point and a USB recovery drive, just in case.
