    I have been unable to install KB4565503 2020-07 Cumulative update for v2004. It tries then says unable to install (no error message) then it says its rolling it back. This continues to occur. The Windows Update troubleshooter doesn’t find anything.  Ideas?

    PS: this is my first post so I apologize in advance if I put this in the wrong place.

      Did you mean KB4565483? Type “winver” (without quotes) in the taskbar search box and hit Enter. Tell us what Edition (Home or Pro) and the Build (it will look like thei 1836x.xxx).
      Then look in Windows Update History and tell us if other Cumulative updates have failed as well.

      Ooops sorry for the typo in the KB, not a good way to start 🙂

      This is win10 x64  version 2004 build 19041.329

      The update that is failing is KB4565503 (cumulative) and KB4565627 .Net framework

      both fail with error 0x800f0922


      • #2281169

        OK, I am going to put the correct KB number in the title, so it you made a link to this topic, it may change.

      • #2281173

        Several things you can try:
        + Turn off Fast Startup (Control Panel\Power options\Choose what power button does)
        + Be sure you have no Pause or deferral (Quality deferral in Group Policy under Windows Update for Business) set. Refer to AKB2000016 Section 5, screenshots below)
        + Be sure Metered connections are set to OFF
        + If you are using a third-party update blocker, check the settings.
        + If you have Malwarebytes installed, temporarily uninstall it. Try disabling any other A/V.

        If none of that works, come back for some other troubleshooting

      Im having the same issue as well as many others.  Ive posted on the Microsoft Community forums.  If I find a solution that works, will post.

    • #2281275


      I’m also having issues with KB4565503 and this forum seems to me to be the best of all I’ve seen regarding this update.

      Like others, KB 4565503 will not install but unlike others I’m not getting any error codes or rollbacks.

      My laptop specs are Windows 10 Home; Version 2004; OS Build 19041.329

      This is the first time I’ve had a problem installing an update. Here’s what happens:

      Automatic Updates were NOT paused. Windows update found 2 updates: KB4565627 Cumulative update for .NET Framework 3.5 & 4.8 for Windows 10 Version 2004 for x64 and KB4565503. The update for NET Framework installed successfully but KB4565503 starts with “downloading 10%” then jumps to “Installing 0%, then 11%, then incremental increases to 20%, then jumps to 44% where it sits for about 3mins then jumps to 100%.

      It then immediately loops back to “downloading 10%, installing etc etc. There is no option to restart the laptop.

      I’ve tried installing it via the “standalone updater” but again it fails. I’ve disconnected all peripherals (mouse, usb port etc), uninstalled Acronis True Image 2020, uninstalled Kaspersky Total Security (after running a full virus scan – nothing found) but it still won’t install. I also have CCleaner installed but that does not run at startup.

      I’ve just checked my update history and found this under “Quality Updates”:

      Update for Windows (KB4565503) (7)

      Last failed install attempt on 16/07/20 – 0x8024200d

      I’ve run “SFC” and nothing found – update still wont install.

      Apart from a clean install of windows (which I really dont want to do) can anyone help with this please ?


    • #2281282

      Go through the steps in #2281173 and #2281175.
      The following must be run from an Administrator ID (not a Standard ID).

      If the problem still exists, verify system file integrity.
      In an elevated Command Prompt (right click on cmd.exe and run as Administrator)
      + chkdsk /f (It will tell you it can’t do it while running, type “Y” to reboot. After reboot,
      + dism /online /cleanup-image /restorehealth
      + sfc /scannow
      Note any errors.

      Reset the Windows Update datastore.
      If you still have the problem, run these commands in an elevated command prompt:
      + dism /online /Cleanup-Image /RevertPendingActions
      + net stop wuauserv
      + net stop cryptSvc
      + net stop bits
      + net stop msiserver
      + Ren C:\Windows\SoftwareDistribution SoftwareDistribution.2007
      + Ren C:\Windows\System32\catroot2 Catroot2.2007
      + net start wuauserv
      + net start cryptSvc
      + net start bits
      + net start msiserver
      If it tells you it cannot rename Catroot2, continue with the rest of the commands.
      Note any errors.
      Verify that C:\Windows\SoftwareDistribution.2007 folder exists.
      Reboot the computer.
      If you had no errors above (other than maybe the Catroot2 rename) try the update again.

        Many thanks for the help.

        I’ve followed all your instructions and also those in #2281173. There is 168GB of free space on the disk so that’s not a problem.

        Verify system file integrity – all completed successfully and no errors were found,

        Reset the Windows Update datastore –

        dism /online /cleanup-Image /RevertPendingActions – completed successfully

        net stop wuauserv – stopped successfully

        net stop cryptSvc – stopped successfully

        net stop bits – stopped successfully

        net stop msiserver – Windows Installer Service is not started

        Ren C:\Windows\SoftwareDistribution SoftwareDistribution.2007 – ACCESS DENIED

        Ren C:\Windows\System32\catroot2 Catroot2.2007 – ACCESS DENIED

        net start wuauserv – already started

        net start cryptSvc – already started

        net start bits – started successfully

        net start msiserver – started successfully

        the folder C:\Windows\SoftwareDistribution.2007 did not exist

        I then went into Powershell (Admin) and input the two Ren commands again and they were successful !!

        Rebooted the laptop but it wouldn’t reboot saying there was problem with the system and it went into Automatic Repair mode. It eventually rebooted and on checking I noticed there are 2 Software Distribution folders (Software distribution and Software Distribution .2007) and 3 catroot folders (catroot; catroot2 and catroot2.2007).

        On checking Windows Update I was surprised to see “You are up to date – last checked 18:30hrs today”. I checked the update history but KB4565503 is not shown as installed so I’ve now paused the updates until 31st July and as I’m away from the laptop tomorrow and Sunday I’ll have another look on Monday, remove the pause and check for updates to see what happens.



    • #2281306

      I had to login to the other user account on my pc and restart it from that account to get it to install properly. Very strange .

    • #2281315

      NOTE, there is also a problem with older Nvidia drivers that will cause v2004 not to install.
      See this thread.

      Hello, I have the exact same issue.

      Installationsfehler: Die Installation des folgenden Updates ist mit Fehler 0x800F0922 fehlgeschlagen: 2020-07 Kumulatives Update für Windows 10 Version 2004 für x64-basierte Systeme (KB4565503)

      Hi, I did the steps without error. Upon reboot I again tried to install the KB4565627 and KB4565503. KB4565627 failed with (of all things) download error 0x8007012f. KB4565503 just sat at “Installing” with no action. After about 20 minutes I rebooted. It just sat saying “getting your system ready [or something like that]” no progress counter just that message. I saw the disk light flash occasionally, after 20 minutes I hard shutdown the system and rebooted. It came up quickly and for the **** of it, I looked at C:\Windows\System32\catroot2 and found a file called dberr.txt. The contents were troubling (compared to what was in the same file in the .2007 directory):

      CatalogDB: 5:04:23 PM 7/17/2020: catdbsvc.cpp at line #1293 encountered JET error -1601
      CatalogDB: 5:04:27 PM 7/17/2020: catdbsvc.cpp at line #1771 encountered error 0x0000012f
      CatalogDB: 5:04:27 PM 7/17/2020: catdbsvc.cpp at line #2223 encountered error 0x0000012f

       I ran sfc /scannow and there was no problem so I will now try a reboot. I am getting the same download error after the reboot.

      Another weird thing is when I try to run MMC.exe as administrator, after about 30 seconds

      I get a UAC popup saying something like “the Administrator has blocked access to this program”

      Its looking like I need to do a reinstall of Windows, I hate to install all the apps again but I am really wasting time with this.  What do you think?

      • #2281419

        Yes, and it would be better if you can go back to 1909 and stay there for a while.
        Woody has repeated “v2004 is not ready yet.” And MS still has multiple blocks.

      Same issue here, i do a clean install and pb persist.

      IS there a pilot at microsoft office?

    • #2281422

      Just to be clear when you said go back to 1909, are you saying uninstall all the recent updates or are you saying do a fresh install and stop at 1909?

      • #2281428

        You do have a backup and a full disk image, don’t you? If not, when this is resolved you should look at setting that up. If you run both immediately before you do an update, you have somewhere to go back to.

        Let me clarify something. You did all the steps in #2281282 successfully and the install still failed?
        If that is the case and you can roll back to June Build 19041.329 or .331 and stay there that might work. I wouldn’t try to install KB4565503 again.

        If you can’t get back to a stable Build of v2004, I would consider moving back to v1909 and waiting a while to upgrade. There are still a lot of problems with v2004.

    • #2281431

      Yes I did all the steps n #2281282 successfully and the install still failed.  In the uninstall update list there isn’t anything going back very far (this is a new machine purchased in June with pre-installed Windows Home which I upgraded to Enterprise).

      What’s odd is in the “view update history” it says it successfully installed both  KB4565503 and KB4565627 on 7/14/2020

      I just checked the list of restore points and the earliest one is is on 7/15.  I guess it wouldn’t hurt to roll back until then and then just stop the updates. What do you think?

      Or would I be better off doing a reinstall. No I do not have a backup. My bad, but in all the years of running Windows I have never run into Windows Update hell. Lessons learned.

      I appreciate your help.

      • #2281433

        Look in installed updates. Control Panel\Programs and Features\Installed Updates and see what the latest installed CU and SSU are. Update history may not tell you what’s really there. If you are on the June Build and you are not having problems, stay there.

        You could try the Restore point if you are having problems, but it may not work.

    • #2281441

      I successfully did the Restore Point restore.  Should I now just keep pausing updates? If so, when do I again continue with them?

      I really appreciate all the help on this issue. I hope to be able to contribute to issues other folks are having.

      • #2281443

        Read through Section 4 & 5 of AKB2000016 carefully. I believe you have Group Policy in Ent. Section 4 applies to v1909 and earlier, but it will give you an idea of the settings I use and why I set them that way.

        You should use Group Policy to control the updates. In Section 5, the settings are what I tried on my v2004 (I’ve only just started looking at it, but they are basically the same as 1990, just in a different place). You should set it up like Section 5 – there are screenshots below to show where the settings are.

        When you get the settings done. Disconnect from your network, Resume Updates (end Pause) and let the attempt fail (you are not connected to the Internet). That should reset the Pause. Reboot (not shutdown/restart) your computer. Don’t reset Pause. When it again checks for updates on its own (don’t click “Check for updates”), with the “2” set, the updates should sit in the queue until you click on the “Download” button. If you don’t want some of them, use wushowhide.diagcab to hide the ones you don’t want. AKB2000013 is also a good reference for what to expect.

        If you have any questions, come back and ask.

    • #2281504

      I did everything you said (including creating a WIM). When it came back up it says “some of the settings are managed by your organization” good, but it also says “error encountered – we couldn’t check because you aren’t connected to the internet”. Apparently, it didn’t bother to check again and was just giving the last error message. It has the option to “retry”. I am assuming you want me to just let it sit, correct?

      • #2281506

        Let it sit till it checks on it’s own. If there are any updates, they should sit in the queue, if you have the “2” set, until you click on the “Download” button.

      This issue appears to be due to a servicing stack issue causing WU downloads to the software distribution location to be unreadable.


      the cabinets are not readable via dism or dism++, i have resolved the issue by grabbing the cabinet for KB4568831 (preview 421) and installing that.

      1 user thanked author for this post.
      • #2283271

        But that bumps you up to a beta of 20H2, doesn’t it?

        Version 2004 is unstable enough. I hesitate to think what 20H2 is like right now….

        Not sure what you meant by

        the cabinets are not readable via dism or dism++

        • #2285493

          No, if you enter the beta ring 20h2 is offered as an optional update.

          The same cabinet is used for 19041.421 and 19042.421

        • #2285494

          Not sure what you meant by


          The cabinets that WU had placed into softwaredistribution\downloads would throw an error when you try to install them via dism, or the dism++ gui tool, my guess is that the cabinets for updates beyond 19041.269 expected an update for the serving stack or it was in a bad configuration following  a /resetbase i had done previously

          This also affected the flash and dotnet security updates for the month, in the dism logs it was shown that the cabinets could not be unpacked and reading the manifests  would fail with a permissions issue of some sort, I did not do further investigation because the system i was experiencing it on was a VM that was still on 19041.269 and came to the conclusion that there was likely a servicing stack update missing or incorrectly installed at the root of it.

          The cabinet for KB4568831 was loaded and installed via dism without issue and and in the DISM logs early in performed an update to the servicing stack before beginning to install the rest of the package,  once rebooted and 421 was confirmed installed, I attempted the updates for flash and dotnet and both installed with no further hassle.

    • #2283819

      Its been 10 days since I did this. All I see is “Updates paused … will resume 8/1/2020”. I expected to see a list of updates and some way to download specific ones. Did I do something wrong?

      • #2288776

        Pausing updates is really a double edged sword. Updates are paused, but so is checking. Even if you use wushowhide (or other) there are no updates shown to hide. cheers, Paul

      I posted this earlier but didn’t see it show up. Apologies if it is a dup.

      I have the updates paused but today decided I wanted the Defender and .Net update but not 2020-08 kb4569745. I ran the WU hiding tool and made sure it was hidden. I then let it download updates. It downloaded and installed Defender, it downloaded and installed .Net update BUT then it downloaded and tried to install kb4569745. Which failed on reboot and rolled itself back. Fortunately the system booted ok.

      Did do something wrong?

      • #2288703

        After an update is hidden, it still needs to be cleared from the queue… and that happens the next time Windows Update looks for updates. Until that happens, it shows up under Windows Update, and will be installed if you ‘check’ for updates, or download and install them. If you want to clear the queue faster than that, go to How to clear the windows update queue in W10 and follow the instructions there. It is easiest just to wait and let it clear itself.

        Also, when you unpause, all the updates that are in the queue are downloaded and installed. That includes any you might have hidden, but which are still in the queue.

    • #2290436

      I fixed the problem by unchecking all .net services in Control Panel\Programs\Programs and Features (Turn Windows Features On or Off) then installing the kb4565503 update.  It installed without problem.  I then went back into Control Panel\Programs\Programs and Features (Turn Windows Features On or Off) and activated the services.
