    Windows 10 Update Problems with KB5003637

    Hello everyone,

    I found this forum while having an update problem with Windows 10 (Build 19042.867) and hope that someone here can help me fixing it. I cannot install the current Windows 10 update KB5003637. The update installs and reaches 100% but then stops with the error code 0x800f081f and unwinds the update process.

    I tried to analyze the error and found several ressources online that point to different possible solutions.
    First, running 'sfc /scannow' and 'dism /online /cleanup-image /restorehealth' and retry the update - no success, same error.

    Then I found a few reports that this update produces this error when Microsoft Edge is uninstalled. Indeed I uninstalled several Windows 10 Apps using the PowerShell's Remove-AppxPackage command. I also uninstalled the Edge Browser, still this is impossible using the PowerShell. For this, I used

    setup.exe --uninstall --system-level --verbose-logging --force-uninstall

    in the 'C:\Program Files (x86)\Microsoft\Edge\Application\<Version>\Installer' directory and thereafter deleted the Legacy Edge Browser by using

    install_wim_tweak.exe /o /c Microsoft-Windows-Internet-Browser-Package /r

    called by a batch file to uninstall Edge Legacy that I found somewhere online.
    So indeed, both Edge versions are removed from my Windows installation. So might this cause this error?

    Anyway, for further testing I tried to reinstall Edge. Reinstalling Edge Chromium works fine, but the update still does not work.
    Additionally, I also tried to reinstall Edge Legacy. I copied the package source directory 'C:\Windows\SystemApps\Microsoft.MicrosoftEdge_8wekyb3d8bbwe' from a working Windows 10 installation, thereafter running in PowerShell

    Get-AppXPackage -AllUsers -Name Microsoft.MicrosoftEdge | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml" -Verbose}

    generally works at first but stops with an IOException. I did not find out any more whats going wrong.

    I know that it is possible to install missing Windows components by using a fresh installation of Windows 10 that keeps all applications and settings, I think this behaves similarly to certain major updates that leave a 'Windows.old' directory. This might be the way to go if nothing else helps, but whats the best way to proceed here? Wait until the update might be fixed by itself? A repair installation seems a bit too much for me here, I think its a pretty simple issue once one know whats going wrong...

    Appreciating any comments. Thanks in advance!

    So indeed, both Edge versions are removed from my Windows installation. So might this cause this error?
    Whilst one update failed with a different code if Edge Chromium was missing, note that

    error code 0x800f081f means CBS_E_SOURCE_MISSING.

    If you have essentially 'hacked' the O/S in various ways, I suppose it's possible that could be a cause- hence again an in-place upgrade repair install may resolve the issue.

    As you may have seen if you searched tenforums that error code was typically resolved with an in-place upgrade repair install.

    Now you could spend time trying to find a specific fix, and you might... I think I recall there was one thread where @Tekkie Boy
    managed to do that. Feel free to look for that thread.

    But also consider this one:
    Windows 10 20H2 OS Build 19042.661 0x800f081f errors when updating

    I suggested an in-place upgrade repair install... other things were tried- time went by- and finally.. an in-place upgrade repair install was recommended.

    Here's one where again the user wanted a specific fix.. but ended up doing in-place upgrade repair install
    Error 0x800f081f in Windows Update with KB4560960

    and another..
    Can't update because of error 0x800f081f

    What do you need to perform an in-place upgrade repair install?

    You have 20H2, so you need either a 20H2 iso file (freely downloadable) - rt click, mount, run setup.exe from new drive- or a bootable 20H2 installation disk (boot normally, log in, run setup.exe from the disk).

    Thanks for the fast, competent and comprehensive response, great!
    I checked the links and also tried to find Tekkie Boy's solution but did not find it. Thus I did an upgrade repair and it seems to Work, great!
    Is this upgrade repair pretty much the same as installing a new major update the leaves a Windows.Old directory or is it something different? It seems to be a pretty useful thing...

    it's a standard kind of ultimate repair option. There's a whole sequence of possible repair options starting with
    disk checks
    a series of possible DISM commands
    an in-place upgrade repair install

    However none of these will fix problems specific to a user account.

    There'a s tutorial on it - do have a look at the tutorial section.

    It uses the same mechanisms as any upgrade, except it takes system files BACK (almost inevitably) to the build of the iso, which must be the same major build and base language and 'bitness'.

    It reverts some registry keys to default and sets services to default.

    This is why sometimes a build upgrade fixes some things, whilst running the risk of introducing new MS bugs.

    Thanks for this information. It seemed to me that this repair upgrade also strips out some stuff, i.e. somehow even cleans the system. Some USB hardware reinstalled the drivers after the update, interesting.
    For the moment I think everything is fixed again, still I'm update my question if I encounter any further issues.
    Thanks a lot!

    I have started win10 and inserted the USB. I started file manager and ran setup. The USB has been blinking for 50 minutes or so, but nothing has appeared on the screen. Is there a problem?

    What's on your USB flash drive?
    How and when did you create it as a Win 10 installable medium?

    Feel free to instead download an iso file of the same major build as you already have and use that, or, if you have 21H1 now, use the MS media creation tool to create a new copy.

    The USB has on it Win10 that I created a month or so ago using the MS Media Creation Tool. I can create a new copy. I now have v20??. Would it be OK to use v21H1?

    I don't know what your current build is from 20??. The forum prompts you thus:
    Windows 10 Update Problems with KB5003637-win-10-version.png

    If you have 20H2, use a 20H2 flash drive to perform an in-place upgrade repair install.
    If you have 21H1, use a 21H1 flash drive to perform an in-place upgrade repair install.

    If you have 20H2, using a 21H1 flash drive to perform an in-place upgrade repair install will upgrade you to 21H1.

    N.B. to perform an in-place upgrade repair install you must boot normally, log in, then browse to the drive and double click setup.exe.

    Thank you so much. I now have a brand new 21H1 USB and will upgrade my 20H2 system in the next day or two. I'll check back when that is done.

    Well, that didn't work. I clicked setup and it started thru the process. It got to the part where it said it needed to check for updates. It did that for a few seconds, then said it needed to reboot, then instantly said something to the effect of it didn't think my laptop could be upgraded. I tried two more times actually doing the reboot, no change. This is rapidly becoming an advertisement for people to switch to linux.

    Should I be doing a full re-install? And will I have any problems with re-registering if I do that?
