    Cumulative Update KB4494441 Windows 10 v1809 Build 17763.503 - May 14


    UPDATE 5/19: Cumulative Update KB4505056 Windows 10 v1809 Build 17763.504 - May 19


    May 14, 2019 - KB4494441 (OS Build 17763.503)

    Applies to: Windows 10 version 1809, Windows Server 2019 all versions


    Note
    This release also contains updates for Microsoft HoloLens (OS Build 17763.502) released May 14, 2019.
    Microsoft will release an update directly to the Windows Update Client to improve Windows Update reliability on Microsoft HoloLens that have not updated to this most recent OS Build.


    Improvements and fixes

    This update includes quality improvements. Key changes include:

    • Enables “Retpoline” by default if Spectre Variant 2 (CVE-2017-5715) is enabled. Make sure previous OS protections against the Spectre Variant 2 vulnerability are enabled using the registry settings described in the Windows Client and Windows Server articles. (These registry settings are enabled by default for Windows Client OS editions, but disabled by default for Windows Server OS editions). For more information about “Retpoline”, see Mitigating Spectre variant 2 with Retpoline on Windows.
    • Provides protections against a new subclass of speculative execution side-channel vulnerabilities, known as Microarchitectural Data Sampling, for 64-Bit (x64) versions of Windows (CVE-2018-11091, CVE-2018-12126, CVE-2018-12127, CVE-2018-12130). Use the registry settings as described in the Windows Client and Windows Server articles. (These registry settings are enabled by default for Windows Client OS editions and Windows Server OS editions).
    • Adds "uk.gov" into the HTTP Strict Transport Security Top Level Domains (HSTS TLD) for Internet Explorer and Microsoft Edge.
    • Addresses an issue that may cause “Error 1309” while installing or uninstalling certain types of .msi and .msp files on a virtual drive.
    • Addresses an issue that prevents the Microsoft Visual Studio Simulator from starting.
    • Addresses an issue that may cause zone transfers between primary and secondary DNS servers over the Transmission Control Protocol (TCP) to fail.
    • Addresses an issue that causes Simple Network Management Protocol (SNMP) Management Information Base registration to fail when the Windows Management Instrumentation (WMI) provider uses the Windows tool SMI2SMIR.exe.
    • Addresses an issue that may cause the text, layout, or cell size to become narrower or wider than expected in Microsoft Excel when using the MS UI Gothic or MS PGothic fonts.
    • Security updates to Microsoft Edge, Internet Explorer, Microsoft Scripting Engine, Windows App Platform and Frameworks, Windows Graphics, Windows Storage and Filesystems, Windows Cryptography, the Microsoft JET Database Engine, Windows Kernel, Windows Virtualization, and Windows Server .

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

    For more information about the resolved security vulnerabilities, please refer to the Security Update Guide.

    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
    After installing this update, there may be issues using the Preboot Execution Environment (PXE) to start a device from a Windows Deployment Services (WDS) server configured to use Variable Window Extension. This may cause the connection to the WDS server to terminate prematurely while downloading the image. This issue does not affect clients or devices that are not using Variable Window Extension. To mitigate the issue, disable the Variable Window Extension on WDS server using one of the following options:

    Option 1:
    Open an Administrator Command prompt and type the following:

    Wdsutil /Set-TransportServer /EnableTftpVariableWindowExtension:No

    Option 2:
    Use the Windows Deployment Services UI.

    1. Open Windows Deployment Services from Windows Administrative Tools.
    2. Expand Servers and right-click a WDS server.
    3. Open its properties and clear the Enable Variable Window Extension box on the TFTP tab.

    Option 3:
    Set the following registry value to 0:

    “HKLM\System\CurrentControlSet\Services\WDSServer\Providers\WDSTFTP\EnableVariableWindowExtension”.

    Restart the WDSServer service after disabling the Variable Window Extension.

    Microsoft is working on a resolution and will provide an update in an upcoming release.
    Certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege. Do one of the following:

    • Perform the operation from a process that has administrator privilege.
    • Perform the operation from a node that doesn’t have CSV ownership.

    Microsoft is working on a resolution and will provide an update in an upcoming release.
    When attempting to print from Microsoft Edge or other Universal Windows Platform (UWP) applications, you may receive the error, "Your printer has experienced an unexpected configuration problem. 0x80070007e." You can use another browser, such as Internet Explorer to print your documents.

    Microsoft is working on a resolution and will provide an update in an upcoming release.
    After installing KB4493509, devices with some Asian language packs installed may receive the error, "0x800f0982 - PSFX_E_MATCHING_COMPONENT_NOT_FOUND."
    1. Uninstall and reinstall any recently added language packs. For instructions, see Manage the input and display language settings in Windows 10.
    2. Select Check for Updates and install the April 2019 Cumulative Update. For instructions, see Update Windows 10.

    Note If reinstalling the language pack does not mitigate the issue, reset your PC as follows:

    1. Go to the Settings app > Recovery.
    2. Select Get Started under the Reset this PCrecovery option.
    3. Select Keep my Files.

    Microsoft is working on a resolution and will provide an update in an upcoming release.
    [ADDED 5/15] Some customers report that KB4494441 installed twice on their device.

    In certain situations, installing an update requires multiple download and restart steps. If two intermediate steps of the installation complete successfully, the View your Update history page will report that installation completed successfully twice.
    No action is required on your part. The update installation may take longer and may require more than one restart, but will install successfully after all intermediate installation steps have completed.

    We are working on improving this update experience to ensure the Update history correctly reflects the installation of the latest cumulative update (LCU).
    [ADDED 5/16] After installing the May 14, 2019 update, some gov.uk websites that don’t support HTTP Strict Transport Security (HSTS) may not be accessible through Internet Explorer 11 or Microsoft Edge. Microsoft is working on a resolution and will provide an update as quickly as possible.

    Failed to install .503 the first time (Installed all of the .NET, etc. downloads) After running the CU a second time, it installed KB4494441 and it is now at 17763.503.
