    Might try manual download and install.

    https://www.catalog.update.microsoft.com/Search.aspx?q=KB4592495

    you'll only need one or the other, KB4592495 is security only. Also check the prerequisite SSU has been downloaded and installed.

    As I mentioned another possibility is a repair install by running setup.exe from the root of the install media, but I give this less than a 5% chance of working.

    Time would likely be better spent standing up a new one. A replacement domain controller could be operational in about 30 minutes.

    Hello Support,

    I did attempted to manual download and install. The issue remains and also when downloading the SSU KB4566425, it says Security update for this patch is already installed. Please, let me know the next steps. These two patches are failing on 3-4 VM Windows 2012 R2 while on others its successful.

    Please, let me know if you need me provide any specific logs which will help. Please, assist furthur.

    May need to check the \windowsupdate.log file for error details. Also try;
    sfc /scannow
    dism /online /cleanup-image /restorehealth
    also the manual steps here.

    Hi,

    I'm not sure about whether this is the reason why you couldn't download updates to your virtual machines but Starting in July 2020, all Windows Updates will disable the RemoteFX vGPU feature because of a security vulnerability.

    You can try to re-enable RemoteFX vGPU then retry.
