 Highlights

  • Updates an issue with using the slider control on the File Open or Save dialog when the system language is set to Hebrew. Options about the size of the file and other details are missing.  

  • Updates an issue that resets syncing for Microsoft OneDrive to “Known folders only” after you install a Windows update. 

Improvements and fixes

This non-security update includes quality improvements. Key changes include:

  • Addresses an issue that prevents users from tracking Distributed Component Object Model (DCOM) activation failures.

  • Addresses an issue that causes the Windows Management Instrumentation (WMI) provider host process to stop working. This occurs because of an unhandled access violation that occurs when using the Desired State Configuration (DSC).

  • Addresses an issue that prevents you from writing to a WMI repository after a low memory condition occurs.

  • Addresses an issue that might prevent you from minimizing an application that uses unthemed windows.

  • Addresses an issue that causes Authentication Mechanism Assurance (AMA) to stop working. This issue occurs when you migrate to Windows Server 2016 (or newer versions of Windows) and when using AMA in conjunction with certificates from Windows Hello for Business.

  • Addresses an issue that prevents Code Integrity rules from working correctly when specifying Package Family Name rules in a Code Integrity policy. This issue occurs because of the incorrect handling of case-sensitive names.

  • Addresses an issue that prevents the ShellHWDetection service from starting on a Privileged Access Workstation (PAW) device and prevents you from managing BitLocker drive encryption.

  • Addresses an issue in Windows Defender Exploit Protection that prevents some Microsoft Office applications from working on machines that have certain processors.

  • Addresses an issue with using the slider control on the File Open or Save dialog when the system language is set to Hebrew. Options about the size of the file and other details are missing.

  • Addresses an issue that might occur when you configure the policy, "Delete user profiles older than a specified number of days on system restart". If a user has been signed in for longer than the time specified in the policy, the device might unexpectedly delete profiles at startup.

  • Addresses an issue with the Microsoft OneDrive sync setting "Always keep on this device". The setting is unexpectedly reset to "Known folders only" after you install a Windows update.

  • Addresses a race condition in the server message block (SMB) client that might slow the I/O for a connection until the I/O times out.

  • Addresses an issue with using the robocopy command with the backup option (/B) to fix copy failures. This issue occurs when the source files contain Alternate Data Streams (ADS) or Extended Attributes (EA) and the destination is an Azure Files share.

  • Addresses a threading issue that might cause the Windows Remote Management (WinRM) service to stop working when under a high load. This is a client solution; so, apply this update to the affected computers that communicate with WinRM.

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

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.

Windows 10 servicing stack update - 17763.2140

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

Symptom

Workaround

After installing KB4493509, devices with some Asian language packs installed may receive the error, "0x800f0982 - PSFX_E_MATCHING_COMPONENT_NOT_FOUND."

This issue is addressed by updates released June 11, 2019 and later. We recommend you install the latest security updates for your device. Customers installing Windows Server 2019 using media should install the latest Servicing Stack Update (SSU) before installing the language pack or other optional components. If using the Volume Licensing Service Center (VLSC), acquire the latest Windows Server 2019 media available. The proper order of installation is as follows:

  1. Install the latest prerequisite SSU, currently KB5005112

  2. Install optional components or language packs

  3. Install latest cumulative update

Note Updating your device will prevent this issue, but will have no effect on devices already affected by this issue. If this issue is present in your device, you will need to use the workaround steps to repair it.

Workaround:

  1. Uninstall and reinstall any recently added language packs. For instructions, see Manage the input and display language settings in Windows 10.

  2. Click Check for Updates and install the April 2019 Cumulative Update or later. For instructions, see Update Windows 10.

Note If reinstalling the language pack does not mitigate the issue, use the In-Place-Upgrade feature. For guidance, see How to do an in-place upgrade on Windows, and Perform an in-place upgrade of Windows Server.

After installing KB5001342 or later, the Cluster Service might fail to start because a Cluster Network Driver is not found.

This issue occurs because of an update to the PnP class drivers used by this service.  After about 20 minutes, you should be able to restart your device and not encounter this issue.
For more information about the specific errors, cause, and workaround for this issue, please see KB5003571.

After installing this or a later update, Windows Server 2019 virtual machines (VMs) employing Software Defined Networks (SDN) or traditional multi-tenant RRAS gateways may lose connectivity with external networks using Gateway connections. Installing the August preview or later update will not affect Windows Server 2019 hosts, Network Controller VMs, and Software Load Balancer VMs.

This issue is resolved in KB5006672.

After installing updates released April 22, 2021 or later, an issue occurs that affects versions of Windows Server that are in use as a Key Management Services (KMS) host. Client devices running Windows 10 Enterprise LTSC 2019 and Windows 10 Enterprise LTSC 2016 might fail to activate. This issue only occurs when using a new Customer Support Volume License Key (CSVLK). 

Note This does not affect activation of any other version or edition of Windows. 

Client devices that are attempting to activate and are affected by this issue might receive the error, "Error: 0xC004F074. The Software Licensing Service reported that the computer could not be activated. No Key Management Service (KMS) could be contacted. Please see the Application Event Log for additional information."

Event Log entries related to activation are another way to tell that you might be affected by this issue. Open Event Viewer on the client device that failed activation and go to Windows Logs > Application. If you see only event ID 12288 without a corresponding event ID 12289, this means one of the following:

  • The KMS client could not reach the KMS host.

  • The KMS host did not respond.

  • The client did not receive the response.

For more information on these event IDs, see Useful KMS client events - Event ID 12288 and Event ID 12289.

This issue is resolved in KB5009616.

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). SSUs improve the reliability of the update process to mitigate potential issues while installing the LCU. For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

Prerequisite:

You must install the August 10, 2021 SSU (KB5005112) before installing the LCU.

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.
