    Hey there, new to this sub. Last night my PC updated. When I tried to log on this morning, my PC made it to 87%, hovered there, and then gave me the error message from the title. I then restarted and did it all over again. I'm not very experienced with computers, so any pointers toward a solution would be much appreciated. Thanks!

    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.
