    After installing updates released May 10, 2022 on your domain controllers, you might see authentication failures on the server or client for services such as Network Policy Server (NPS), Routing and Remote access Service (RRAS), Radius, Extensible Authentication Protocol (EAP), and Protected Extensible Authentication Protocol (PEAP). An issue has been found related to how the mapping of certificates to machine accounts is being handled by the domain controller.

    Note: Installation of updates released May 10, 2022, on client Windows devices and non-domain controller Windows Servers will not cause this issue. This issue only affects installation of May 10, 2022, updates installed on servers used as domain controllers.

    Workaround: The preferred mitigation for this issue is to manually map certificates to a machine account in Active Directory. For instructions, please see Certificate Mapping. Note: The instructions are the same for mapping certificates to user or machine accounts in Active Directory. If the preferred mitigation will not work in your environment, please see KB5014754—Certificate-based authentication changes on Windows domain controllers for other possible mitigations in the SChannel registry key section. Note: Any other mitigation except the preferred mitigations might lower or disable security hardening.

    Next steps: We are presently investigating and will provide an update in an upcoming release.

    After installing KB5012643, some .NET Framework 3.5 apps might have issues or might fail to open. Affected apps are using certain optional components in .NET Framework 3.5, such as Windows Communication Foundation (WCF) and Windows Workflow (WWF) components.

    Workaround: You can mitigate this issue by re-enabling .NET Framework 3.5 and the Windows Communication Foundation in Windows Features. For instructions, please see Enable the .NET Framework 3.5 in Control Panel. Advanced users or IT admins can do this programmatically using an elevated Command Prompt (run as administrator) and running the following commands:

    dism /online /enable-feature /featurename:netfx3 /all
    dism /online /enable-feature /featurename:WCF-HTTP-Activation
    dism /online /enable-feature /featurename:WCF-NonHTTP-Activation
    

    Next steps: We are working on a resolution and will provide an update in an upcoming release.

    After installing KB5012643, Windows devices using certain GPUs might have apps close unexpectedly or intermittent issues with some apps which use Direct3D 9. You might also receive an error in Event Log in Windows Logs/Applications with faulting module d3d9on12.dll and exception code 0xc0000094.

    Resolution: This issue is resolved using Known Issue Rollback (KIR). Please note that it might take up to 24 hours for the resolution to propagate automatically to consumer devices and non-managed business devices. Restarting your Windows device might help the resolution apply to your device faster. For enterprise-managed, devices that have installed an affected update and encountered this issue can resolve it by installing and configuring the special Group Policy listed below. For information on deploying and configuring these special Group Policies, please see How to use Group Policy to deploy a Known Issue Rollback.

    After installing KB5012643, devices starting in Safe Mode might show a flickering screen. Components that rely on Explorer.exe, such as File Explorer, Start Menu, and Taskbar, can be affected and appear unstable.

    Devices experiencing this issue can log a System error on the Windows Event Log, with Source “Winlogon” and the following description: “The shell stopped unexpectedly and explorer.exe was restarted”.

    Workaround: This issue happens when the device is started using the “Safe Mode without Networking” option. If Safe Mode needs to be engaged, please select “Safe Mode with Networking” option as a workaround. Please refer to this document for more details on how to start your device in Safe Mode with Networking: Start your PC in safe mode in Windows (microsoft.com)

    Resolution: This issue was resolved in updates released May 10, 2022, and later. We recommend you install the latest security update for your device as it contains important improvements and issues resolutions, including this one. If you install an update released May 10, 2022 or later, you do not need to use a Known Issue Rollback (KIR) or a special Group Policy to resolve this issue.

    If you are using an update released before May 10, 2022, you can resolve this issue using KIR. Enterprise-managed devices that have installed an affected update and encountered this issue can resolve it by installing and configuring the special Group Policy listed below.

    Compatibility issues with Intel Smart Sound Technology drivers and Windows 11

    Intel and Microsoft have found incompatibility issues with certain versions of drivers for Intel Smart Sound Technology (Intel SST) and Windows 11. Windows 11 devices with the affected Intel SST driver might receive an error with a blue screen. The affected driver will be named Intel® Smart Sound Technology (Intel® SST) Audio Controller under System Devices in Device Manager and have the file name IntcAudioBus.sys and a file version of 10.29.0.5152 and earlier or 10.30.0.5152 and earlier.

    To safeguard your upgrade experience, we have applied a compatibility hold on devices with affected Intel SST drivers from being offered Windows 11. If your organization is using Update Compliance, the safeguard ID is 36899911.

    Workaround: To mitigate the safeguard, you will need to check with your device manufacturer (OEM) to see if an updated driver is available and install it. This issue is resolved by updating the Intel® Smart Sound Technology drivers to a version 10.30.00.5714 and later or 10.29.00.5714 and later. Important: Later versions refer to just the last part of the version number. For addressing this issue, 10.30.x versions are not newer than 10.29.x versions. Once you have updated to a compatible version of the Intel® Smart Sound Technology drivers, you should be able to upgrade to Windows 11. Please note, if there are no other safeguards that affect your device, it can take up to 48 hours before the upgrade to Windows 11 is offered.

    Next Steps: If you encounter this safeguard hold and an updated driver is not yet available, you will need to contact your device manufacturer (OEM) for more information.

    Note We recommend that you do not attempt to manually upgrade using the Update now button or the Media Creation Tool until this issue has been resolved and the safeguard removed.
