Highlights

  • Updates security for your Windows operating system.   

Improvements and fixes

This security update includes quality improvements. Key changes include: 

  • Addresses a known issue that prevents an internet print server from properly packaging modified printer properties before sending the package to the client.

  • Addresses an issue that prevents some applications, such as Microsoft Office and Adobe Reader, from opening or causes them to stop responding. This occurs on devices that are subject to Microsoft Exploit Protection for Export Address Filtering (EAF).

  • Addresses a known issue with Windows Server 2019 virtual machines (VMs) that use Software Defined Networks (SDN) or traditional multi-tenant Routing and Remote Access service (RRAS) gateways. These VMs might lose connectivity with external networks that use gateway connections. This issue occurs after installing KB5005102 or a later Windows update.

  • Addresses a known issue that might ask for administrative credentials every time you attempt to print. This occurs in environments in which the print server and print client are in different times zones.

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 new Security Update Guide website and the October 2021 Security Updates.

Windows 10 servicing stack update - 17763.2170

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 KB5005568, installation of printers using Internet Printing Protocol (IPP) might not complete successfully. Devices which had connected to and installed the printer prior to the installation of KB5005568 are unaffected and print operations to that printer will succeed as usual.

Note IPP is not commonly used by devices designed for home use. Printing environments affected by this issue are more commonly found in enterprises and organizations.

Microsoft is working on a resolution and targeting its release in a future update.

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.
