    Dell Inspirion 15 Windows 10, stuck for two hours at 35 percent update. Blue screen. Please help. I am not a techie.

    Update: Blue screen now says "We couldn't complete the updates. Undoing changes." It has been that way for 15 minutes.

    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.

    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.
