    • Improves startup times for applications that have roaming settings when User Experience Virtualization (UE-V) is turned on.
    • Addresses an issue in which a principal in a trusted MIT realm fails to obtain a Kerberos service ticket from Active Directory domain controllers (DC). This occurs on devices that installed Windows Updates that contain CVE-2020-17049 protections and configured PerfromTicketSignature to 1 or higher. These updates were released between November 10, 2020 and December 8, 2020. Ticket acquisition also fails with the error, “KRB_GENERIC_ERROR”, if callers submit a PAC-less Ticket Granting Ticket (TGT) as an evidence ticket without providing the USER_NO_AUTH_DATA_REQUIRED flag.
    • Addresses high memory and CPU utilization in Microsoft Defender for Endpoint.
    • Enhances data loss prevention and insider risk management solution functionalities in Microsoft 365 endpoints.

        • Default value = 1; enables the log.
        • Value other than 1; disables the log.

    If this key does not exist, it will be created automatically. To take effect, any change to
    dfslog/RootShareAcquireSuccessEvent in the registry requires that you restart the DFSN service.

    • Updates the Open Mobile Alliance (OMA) Device Management (DM) sync protocol by adding a check-in reason for requests from the client to the server. The check-in reason will allow the mobile device management (MDM) service to make better decisions about sync sessions. With this change, the OMA-DM service must negotiate a protocol version of 4.0 with the Windows OMA-DM client.
    • Turns off token binding by default in Windows Internet (WinINet).
    • Addresses an issue with failover in an environment that only has IPv6 clusters. If the failover cluster has been running for more than 24 days, attempts to do a failover might not succeed or might be delayed.

    If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.

    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

    Symptoms 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.
    When using the Microsoft Japanese Input Method Editor (IME) to enter Kanji characters in an app that automatically allows the input of Furigana characters, you might not get the correct Furigana characters. You might need to enter the Furigana characters manually.

    Note The affected apps are using the ImmGetCompositionString() function.
    We are working on a resolution and will provide an update in an upcoming release.

    How to get this update

    Before installing this update

    Prerequisite:

    Starting with this release, Microsoft will combine the latest servicing stack update (SSU) for your operating system with the latest cumulative update (LCU). To utilize this improvement, install the most recent standalone SSU (KB4598481) before installing this LCU. If you install this LCU before installing KB4598481, you might encounter error 0x800f0823 – CBS_E_NEW_SERVICING_STACK_REQUIRED. Close the error message and install the recommended SSU.

    For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

    Install this update

    Release Channel Available Next Step
    Windows Update or Microsoft Update Yes Go to Settings > Update & Security > Windows Update. In the Optional updates available area, you’ll find the link to download and install the update.
    Microsoft Update Catalog Yes To get the standalone package for this update, go to the Microsoft Update Catalog website.
    Windows Server Update Services (WSUS) No You can import this update into WSUS manually. See the Microsoft Update Catalog for instructions.

    If you want to remove the LCU
    To remove the LCU after installing the combined SSU and LCU package, use the DISM/Remove-Package command line option with the LCU package name as the argument. You can find the package name by using this command: DISM /online /get-packages.
    Running Windows Update Standalone Installer (wusa.exe) with the /uninstall switch on the combined package will not work because the combined package contains the SSU. You cannot remove the SSU from the system after installation.

    Weird update...
    First I installed the .NET Framework update (KB4601554), then installed KB4601382, which also installed KB5000911.
    Apparently KB5000911 is 1904x.841
    During the install it went to 100% TWICE.

    Yup, been offered to me as well, and I'm not an insider!

    BTW I see that there's another .NET "preview" there as well, not being offered as optional!
    Not seeing that yet.

    EDIT.
    Er, how come my post is suddenly in a completely different thread?!
    Makes a nonsense of what I'm referring to.
    It's this.

    @Brink

    Shawn, I think that the new SSU is KB5000911 and not KB4598481.
    The KB4598481, you mention in the 1st post, is the SSU from Jan. 12, 2021.
    Maybe you should consider changing the 1st post, with regards to the updated SSU.

    Hello Dimitri,

    Yeah, I'm not sure why Microsoft still referenced KB4598481 in the release notes instead of KB5000911.

    I can't find any separate release page or download from the Microsoft Update Catalog for KB5000911 yet to reference here.
