    Windows Server 2025 is intended to be offered as an Optional upgrade in Windows Update settings for devices running Windows Server 2019 and Windows Server 2022. Two scenarios were observed in certain environments:

    • ​Some devices upgraded automatically to Windows Server 2025 (KB5044284). This was observed in environments that use third-party products to manage the update of clients and servers. Please verify whether third-party update software in your environment is configured not to deploy feature updates. This scenario has been mitigated.
    • ​An upgrade to Windows Server 2025 was offered via a message in a banner displayed on the device’s Windows Update page, under Settings. This message is intended for organizations that want to execute an in-place upgrade. This scenario has already been resolved.

    The Windows Server 2025 feature update was released as an Optional update under the Upgrade Classification: “DeploymentAction=OptionalInstallation”. Feature update metadata must be interpreted as Optional and not Recommended by patch management tools.

    We advise organizations to use Microsoft-recommended methods to deploy Windows Server feature updates.

    Next steps: Microsoft is working with third-party providers to streamline best practices and recommended procedures. The visibility of the feature update offer banner can be controlled by setting the target version to “hold” in the Group Policy “Select the target Feature Update version”. We will update this documentation in the coming days with additional information about this group policy once it is available.

    Note: The Windows Server 2025 feature update was made generally available on November 1, 2024, as KB5044284, which was the same KB number used for Windows 11, version 24H2. This was the KB numbering for both these client and server Windows updates available at that time. Future updates released for Windows Server 2025 and Windows 11, version 24H2 will share the same KB numbers, but will have different release note sites and links.

    August 2024 security update might impact Linux boot in dual-boot setup devices

    After installing the August 2024 Windows security update, (KB5041578) or the August 2024 preview update, you might face issues with booting Linux if you have enabled the dual-boot setup for Windows and Linux in your device. Resulting from this issue, your device might fail to boot Linux and show the error message “Verifying shim SBAT data failed: Security Policy Violation. Something has gone seriously wrong: SBAT self-check failed: Security Policy Violation.”

    The August 2024 Windows security and preview updates apply a Secure Boot Advanced Targeting (SBAT) setting to devices that run Windows to block old, vulnerable boot managers. This SBAT update will not be applied to devices where dual booting is detected. On some devices, the dual-boot detection did not detect some customized methods of dual-booting and applied the SBAT value when it should not have been applied.

    IMPORTANT: This known issue only occurs with the installation of the August 2024 security and preview updates. The September 2024 security update (KB5043050) and later updates do not contain the settings that caused this issue. If you install the September 2024 update, you don’t need to apply the workaround below.

    Workaround:

    If your Linux becomes unbootable after installing the August 2024 security or preview updates, you can recover your Linux system by following these instructions.

    Important: This documentation contains information about how to modify the registry. Make sure that you back up the registry before you modify it. Make sure that you know how to restore the registry if a problem occurs. For more information about how to back up, restore, and modify the registry, see How to back up and restore the registry in Windows. Also, note that modifying firmware settings incorrectly might prevent your device from starting correctly. Follow these instructions carefully and only proceed if you are confident in your ability to do so.

            a) Disable Secure Boot:

    • ​Boot into your device’s firmware settings.
    • ​Disable Secure Boot (steps vary by manufacturer).
            b) Delete SBAT Update:

    • ​Boot into Linux.
    • ​Open the terminal and run the below command:
    sudo mokutil --set-sbat-policy delete
    • ​Enter your root password if prompted.
    • ​Boot into Linux once more.
            c) Verify SBAT Revocations:

    • ​In the terminal, run the below command:
    mokutil --list-sbat-revocations
    • ​Ensure the list shows no revocations.
            d) Re-enable Secure Boot:

    • ​Reboot into the firmware settings.
    • ​Re-enable Secure Boot.
            e) Check Secure Boot Status:

    • ​Boot into Linux. Run the below command:
     mokutil --sb-state
    • ​The output should be “SecureBoot enabled”. If not, retry step d).
            f) Prevent Future SBAT Updates in Windows:

    • ​Boot into Windows.
    • ​Open Command Prompt as Administrator and run:
    reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecureBoot\SBAT /v OptOut /d 1 /t REG_DWORD

    At this point, you should now be able to boot into Linux or Windows as before. It’s a good time to install any pending Linux updates to ensure your system is secure.

    NOTE: On Windows-only systems, after installing the September 2024 or later updates, you can set the registry key documented in CVE-2022-2601 and CVE-2023-40547 to ensure the SBAT security update is applied. On systems that dual-boot Linux and Windows, there are no additional steps necessary after installing the September 2024 or later updates.

    Next Steps: We are working on a final resolution that will be available in a future Windows update. We recommend you install the September 2024 update or later Windows updates to avoid this issue.

    After installing updates released January 11, 2022 or later, apps using Microsoft .NET Framework to acquire or set Active Directory Forest Trust Information might fail, close, or you might receive an error from the app or Windows. You might also receive an access violation (0xc0000005) error. Note for developers: Affected apps use the System.DirectoryServices API.

    Next Steps: This issue was resolved in the out-of-band update for the version of .NET Framework used by the app. Note: These out-of-band updates are not available from Windows Update and will not install automatically. To get the standalone package, search for the KB number for your version of Windows and .NET Framework in the Microsoft Update Catalog. You can manually import these updates into Windows Server Update Services (WSUS) and Microsoft Endpoint Configuration Manager. For WSUS instructions, see WSUS and the Catalog Site. For Configuration Manger instructions, see Import updates from the Microsoft Update Catalog.

    For instructions on how to install this update for your operating system, see the KB articles listed below:
