Cumulative Update for Windows 10 (KB3081424) fails to install and reboots with error: “We couldn’t complete the updates. Undoing changes.”

After installing Windows 10, when I try to install Windows Update KB3081424, it says “We couldn’t complete the updates.  Undoing the changes”, and then reboots.  When I check the Event Logs, it shows Error 0x80070003.  The update then repeatedly fails with this error each time it tries to install.

How do I resolve this?



We have released a fix for this issue through Windows Update in KB3081440.  This update repairs a problem involving user profiles that may have prevented KB3801424 from installing on some systems.  This fix should install automatically when updates are scheduled to run, and should resolve most customers. 


If you are still experiencing this issue, or if Windows Update is not installing the fix, try manually installing KB3081440 directly from the Microsoft Update Catalog.  Select the appropriate update for your operating system.  You can look up your system type (32-bit or 64-bit) by right-clicking the Start icon and selecting System.


If installing KB3081440 manually does not resolve your issue, please post your problem to the forums.
