    Windows Update Improvements
    Microsoft has released an update directly to the Windows Update client to improve reliability. Any device running Windows 10 configured to receive updates automatically from Windows Update, including Enterprise and Pro editions, will be offered the latest Windows 10 feature update based on device compatibility and Windows Update for Business deferral policy. This doesn't apply to long-term servicing editions.

    Known issues in this update

    Symptom Workaround
    System and user certificates might be lost when updating a device from Windows 10, version 1809 or later to a later version of Windows 10. Devices will only be impacted if they have already installed any Latest cumulative update (LCU) released September 16, 2020 or later and then proceed to update to a later version of Windows 10 from media or an installation source which does not have an LCU released October 13, 2020 or later integrated. This primarily happens when managed devices are updated using outdated bundles or media through an update management tool such as Windows Server Update Services (WSUS) or Microsoft Endpoint Configuration Manager. This might also happen when using outdated physical media or ISO images that do not have the latest updates integrated.

    Note Devices using Windows Update for Business or that connect directly to Windows Update are not impacted. Any device connecting to Windows Update should always receive the latest versions of the feature update, including the latest LCU, without any extra steps.
    If you have already encountered this issue on your device, you can mitigate it within the uninstall window by going back to your previous version of Windows using the instructions here. The uninstall window might be 10 or 30 days depending on the configuration of your environment and the version you’re updating to. You will then need to update to the later version of Windows 10 after the issue is resolved in your environment. Note Within the uninstall window, you can increase the number of days you have to go back to your previous version of Windows 10 by using the DISM command /Set-OSUninstallWindow. You must make this change before the default uninstall window has lapsed. For more information, see DISM operating system uninstall command-line options.

    We are working on a resolution and will provide updated bundles and refreshed media in the coming weeks.
    [ADDED 3/10] After installing this update, you might receive an APC_INDEX_MISMATCH error with a blue screen when attempting to print to certain printers in some apps. We are presently investigating and will provide an update when more information is available.

    How to get this update

    Before installing this update

    Microsoft strongly recommends you install the latest servicing stack update (SSU) for your operating system before installing the latest cumulative update (LCU). SSUs improve the reliability of the update process to mitigate potential issues while installing the LCU and applying Microsoft security fixes. For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

    If you are using Windows Update, the latest SSU (KB5000908) will be offered to you automatically. To get the standalone package for the latest SSU, search for it in the Microsoft Update Catalog.

    Microsoft offers a temporary workaround for Error when attempting to print to certain printers. You might receive an APC_INDEX_MISMATCH error with a blue screen when attempting to print.

    https://docs.microsoft.com/en-us/win...h2#1570msgdesc

    Workaround: To mitigate the issue, follow the instructions in this video. The Command Prompt commands from the video are as follows (you will need to replace KX driver for Universal printing with the name of your printer, as explained in the video):

    • rundll32 printui.dll,PrintUIEntry /Xg /n “KX driver for Universal printing”
    • rundll32 printui.dll,PrintUIEntry /Xs /n "KX driver for Universal printing" attributes +direct
