    Windows 10 servicing stack update - 19041.1310, 19042.1310, and 19043.1310

    • This update makes quality improvements to the servicing stack, which is the component that installs Windows updates. Servicing stack updates (SSU) ensure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates.

    Known issues in this update

    Symptoms Workaround
    Devices with Windows installations created from custom offline media or custom ISO image might have Microsoft Edge Legacy removed by this update, but not automatically replaced by the new Microsoft Edge. This issue is only encountered when custom offline media or ISO images are created by slipstreaming this update into the image without having first installed the standalone servicing stack update (SSU) released March 29, 2021 or later.

    Note Devices that connect directly to Windows Update to receive updates are not affected. This includes devices using Windows Update for Business. Any device connecting to Windows Update should always receive the latest versions of the SSU and latest cumulative update (LCU) without any extra steps.
    To avoid this issue, be sure to first slipstream the SSU released March 29, 2021 or later into the custom offline media or ISO image before slipstreaming the LCU. To do this with the combined SSU and LCU packages now used for Windows 10, version 20H2 and Windows 10, version 2004, you will need to extract the SSU from the combined package. Use the following steps to extract the using SSU:

    1. Extract the cab from the msu via this command line (using the package for KB5000842 as an example): expand Windows10.0-KB5000842-x64.msu /f:Windows10.0-KB5000842-x64.cab <destination path>
    2. Extract the SSU from the previously extracted cab via this command line: expand Windows10.0-KB5000842-x64.cab /f:* <destination path>
    3. You will then have the SSU cab, in this example named SSU-19041.903-x64.cab. Slipstream this file into your offline image first, then the LCU.

    If you have already encountered this issue by installing the OS using affected custom media, you can mitigate it by directly installing the new Microsoft Edge. If you need to broadly deploy the new Microsoft Edge for business, see Download and deploy Microsoft Edge for business.
    After installing the June 21, 2021 (KB5003690) update, some devices cannot install new updates, such as the July 6, 2021 (KB5004945) or later updates. You will receive the error message, "PSFX_E_MATCHING_BINARY_MISSING". For more information and a workaround, see KB5005322.
    After installing this update, when connecting to devices in an untrusted domain using Remote Desktop, connections might fail to authenticate when using smart card authentication. You might receive the prompt, "Your credentials did not work. The credentials that were used to connect to [device name] did not work. Please enter new credentials." and "The login attempt failed" in red. 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 non-managed personal 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, it can be resolved by installing and configuring a special Group Policy linked below. Note Devices need to be restarted after configuring the special Group Policy. For help, please see How to use Group Policy to deploy a Known Issue Rollback. For general information on using Group Policies, see Group Policy Overview.
    Group Policy installation files:


    Important Verify that you are using the correct Group Policy for your version of Windows.

    How to get this update

    Before installing this update

    Microsoft now combines the latest servicing stack update (SSU) for your operating system with the latest cumulative update (LCU). For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

    Prerequisite:

    For Windows Server Update Services (WSUS) deployment or when installing the standalone package from Microsoft Update Catalog:

    If your devices do not have the May 11, 2021 update (KB5003173) or later LCU, you must install the special standalone August 10, 2021 SSU (KB5005260).

    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.
    Windows Update for Business No None. These changes will be included in the next security update to this channel.
    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.

    For a list of the files that are provided in the servicing stack update, download the file information for the SSU - version 19041.1310, 19042.1310, and 19043.1310.

    Hello mate,

    You could try right clicking on the download link, and use "Open in new tab" or "Open in new window" to see if that may allow it to download.

    If not, try a different browser.

    Oh, I can right click the entry in the downloads window and allow the download.
    But I have NEVER seen this before, no matter what or where I download, anything, from.

    Me too. That's because it's a download from an insecure http server, not https.

    http://download.windowsupdate.com/....

    But click on the download notice to see more details and Firefox will let you choose to download it anyway.

    Almost everywhere else you download from will be using HTTPS, so there's no security risk for Firefox to complain about. Goodness only knows why MS are still using HTTP.
