Improvements and fixes

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

  • Addresses an issue with PropertyGet in JScript9.dll.

  • Addresses an issue with Assigned Access kiosks that are configured with Microsoft Edge as a kiosk application. These kiosks might sometimes fail to restart Microsoft Edge if users close the browser window.

  • Addresses an issue in which the use of App-V intermittently causes black screens to appear when signing in on the credentials page.

  • Addresses an issue that causes Windows to go into BitLocker recovery after a servicing update.

  • Addresses an issue that causes searchindexer.exe to keep handles to the per user search database in the path below after you sign out: “C:\Users\username\AppData\Roaming\Microsoft\Search\Data\Applications\<SID>\” As a result, searchindexer.exe stops working and duplicate profile names are created.

  • Addresses an issue that causes the DnsPsProvider.dll module to leak memory within a WmiPrvSE.exe process.

  • Addresses an issue that prevents Windows 10 virtual private network (VPN) users from connecting to Windows Server 2019 Routing and Remote Access service (RRAS) servers.

  • Addresses an issue that prevents Software-Defined Networking (SDN) virtual machines from working when you configure the Generic Routing Encapsulation (GRE) VPN bandwidth limitation.

  • Addresses an issue in Code Integrity that might cause a memory leak.

  • Enhances Microsoft Defender for Endpoint’s ability to identify and intercept ransomware and advanced attacks.

  • Addresses a memory leak issue in lsass.exe on domain controllers in the forest root domain that occurs when you have multiple forests and multiple domains in each forest. The SID-Name mapping functions leak memory when a request comes from another domain in the forest and crosses forest boundaries.

  • Improves the Windows Server Storage Migration Service by adding support for migration Windows Servers configured with Azure File Sync cloud tiering. Additionally, this update addresses multiple issues and improves reliability. For more information, see Storage Migration Service overview.

  • Addresses an issue with the virtual machine (VM) Load Balancing feature, which ignores a site’s fault domain.

  • Addresses a known issue that might prevent the successful installation of printers using the Internet Printing Protocol (IPP).

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

Windows 10 servicing stack update - 17763.2262

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."

  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 PC recovery option.

  3. Select Keep my Files.

Microsoft is working on a resolution and will provide an update in an upcoming release.

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 update, Windows print clients might encounter the following errors when connecting to a remote printer shared on a Windows print server:

  • 0x000006e4 (RPC_S_CANNOT_SUPPORT)

  • 0x0000007c (ERROR_INVALID_LEVEL)

  • 0x00000709 (ERROR_INVALID_PRINTER_NAME)

Note The printer connection issues described in this issue are specific to print servers and are not commonly observed in devices designed for home use. Printing environments affected by this issue are more commonly found in enterprises and organizations.

This issue is resolved in KB5007266.

After installing this or later updates, Microsoft Defender for Endpoint might fail to start or run on devices with a Windows Server Core installation. 

Note This issue does not affect Microsoft Defender for Endpoint on Windows 10.

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

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.
