    IMPORTANT Release notes are changing! To learn about the new URL, metadata updates, and more, see What’s next for Windows release notes.


    IMPORTANT Starting in July 2020, we will resume non-security releases for Windows 10 and Windows Server, version 1809 and later. There is no change to the cumulative monthly security updates (also referred to as the "B" release or Update Tuesday release). For more information, see the blog post Resuming optional Windows 10 and Windows Server non-security monthly updates.

    IMPORTANT Starting in July 2020, all Windows Updates will disable the RemoteFX vGPU feature because of a security vulnerability. For more information about the vulnerability, see CVE-2020-1036 and KB4570006. After you install this update, attempts to start virtual machines (VM) that have RemoteFX vGPU enabled will fail, and messages such as the following will appear:
    “The virtual machine cannot be started because all the RemoteFX-capable GPUs are disabled in Hyper-V Manager.”
    “The virtual machine cannot be started because the server has insufficient GPU resources.”
    If you re-enable RemoteFX vGPU, a message similar to the following will appear:
    "We no longer support the RemoteFX 3D video adapter. If you are still using this adapter, you may become vulnerable to security risk. Learn more (https://go.microsoft.com/fwlink/?linkid=2131976)

    [ADDED 10/23] Windows 10, version 20H2
    This security update includes quality improvements. Key changes include:

    1. This build includes all the improvements from Windows 10, version 2004.
    2. No additional issues were documented for this release.

    Windows 10, version 2004

    This security update includes quality improvements. Key changes include:

    • Addresses an issue with a possible elevation of privilege in win32k.
    • Addresses an issue with the Group Policy service that might recursively delete critical files in alphabetic order from %systemroot%\systm32. This issue occurs when a policy has been configured to delete cached profiles. These file deletions might cause stop error “0x5A (CRITICAL_SERVICE_FAILED)” boot failures.
    • Addresses an issue with creating null ports using the user interface.
    • Security updates to Windows App Platform and Frameworks, Microsoft Graphics Component, Windows Media, Windows Fundamentals, Windows Authentication, Windows Virtualization, and Windows Kernel.

    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
    Users of the Microsoft Input Method Editor (IME) for Japanese or Chinese languages might experience issues when attempting various tasks. You might have issues with input, receive unexpected results, or might not be able to enter text. For more information about the issues, workaround steps, and the currently resolved issues, please see KB4564002
    When installing a third-party driver, you might receive the error, “Windows can’t verify the publisher of this driver software”. You might also see the error, “No signature was present in the subject” when attempting to view the signature properties using Windows Explorer. This issue occurs when an improperly formatted catalog file is identified during validation by Windows. Starting with this release, Windows will require the validity of DER encoded PKCS#7 content in catalog files. Catalogs files must be signed per section 11.6 of describing DER-encoding for SET OF members in X.690.

    If this happens you should contact the driver vendor or device manufacturer (OEM) and ask them for an updated driver to correct the issue.

    How to get this update

    Before installing this update

    Microsoft strongly recommends you install the latest servicing stack update (SSU) for your operating system before installing the latest cumulative update (LCU). SSUs improve the reliability of the update process to mitigate potential issues while installing the LCU and applying Microsoft security fixes. For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

    If you are using Windows Update, the latest SSU (KB4577266) will be offered to you automatically. To get the standalone package for the latest SSU, search for it in the Microsoft Update Catalog.

    Release Channel Available Next Step
    Windows Update and Microsoft Update Yes None. This update will be downloaded and installed automatically from Windows 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) Yes This update will automatically sync with WSUS if you configure Products and Classifications as follows:
    Product: Windows 10, version 1903 and later
    Classification: Security Updates

    File information

    For a list of the files that are provided in this update, download the file information for cumulative update 4579311.

    Note Some files erroneously have “Not applicable” in the “File version” column of the CSV file. This might lead to false positives or false negatives when using some third-party scan detection tools to validate the build.

    What are you supposed to do if it offers a restart after cumulative update for net framework has done its thing. But the main cumulative update says it’s still installing . Wait til both are finished? I guess that’s what i will do but don’t recall seeing that before

    Either way will work. It's been happening this way for the past couple months.
