I am trying to install KB4592438 for Windows 10 20H2. The patch is downloaded without any issue. But the installation fails and the screen starts showing - Undoing changes Don't turn off your computer. The error message is - Some update files are missing or have problems. We'll try to download the update again later. Error code: (0x80070003).

    I've been reading this chain with growing dismay.  As a reasonably tech-savvy user of W10, I just want the update process to work, and it doesn't!  All the ridiculously complex processes outlined above should NOT be needed.

    If there's a fault in the update, Microsoft need to GET THIS FIXED!!

    Raju,

    I was thinking about this route myself but it is a destructive method  - in the Chose what to keep dialog, the 'keep personal files and apps' (and keep personal files only' are grayed out, only 'Nothing' ie destructive method is possible. The same if I boot from the installation media. So it seems that you cannot perform a non-destructive upgrade if the installed version and the installation media's version are identical.

    I also tried with the equivalent offline installer (windows10.0-kb4592438-x64_b6914251264f8f973c3f82f99b894935f33c38e6.msu). It fails too - different error (0x8024200b) but probably related. 

    Unless someone has a different idea, I'll wait until next month for a new cumulative update (or a re-release as it seems several people have encountered the same issue). While not the first time I've encountered issues with Windows updates, it is the first where none of the otherwise proven troubleshooting measures seem to work.

    I agree with you Roland. I got the same issue and I don't understand why would I need to re-image my whole computer just to complete a cumulative update??? It does not make sense.

    I have the same issue. Followed all of the above steps - december SSU was already installed

    C:\Windows\system32>sfc /scannow

    Beginning system scan.  This process will take some time.

    Beginning verification phase of system scan.

    Verification 100% complete.

    Windows Resource Protection did not find any integrity violations.

    C:\Windows\system32>dism /online /cleanup-image /restorehealth

    Deployment Image Servicing and Management tool

    Version: 10.0.19041.572

    Image Version: 10.0.19042.630

    [===========================84.9%=================         ]

    [===========================86.1%=================         ]

    [===========================87.3%==================        ]

    [===========================88.7%===================       ]

    [===========================89.9%====================      ]

    [===========================91.1%====================      ]

    [==========================100.0%==========================] The restore operation completed successfully.

    The operation completed successfully.

    Same result - the installation fails with error 0x80070003
