Highlights 

  • Updates security for your Windows operating system.   

Improvements and fixes

This security update includes quality improvements. Key changes include:

  • Addresses known compatibility issues between some Intel “Killer” and “SmartByte” networking software and Windows 11 (original release). Devices with the affected software might drop User Datagram Protocol (UDP) packets under certain conditions. This creates performance and other issues for protocols based on UDP. For example, some websites might load slower than others on the affected devices, which might cause videos to stream slower in certain resolutions. VPN solutions based on UDP might also be slower. 

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 website and the October 2021 Security Updates.

Windows 11 servicing stack update - 22000.190

  • 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

Devices which attempt to connect to a network printer for the first time might fail to download and install the necessary printer drivers.

This issue has been observed in devices which access printers via a print server, using HTTP connections. When a client connects to the server to install the printer, a directory mismatch occurs, which causes the installer files to generate incorrectly. As a result, the drivers may not download.

Note: The printer connection methods described in this issue are not commonly used by devices designed for home use. The printing environments affected by this issue are more commonly found in enterprises and organizations.

IT administrators with admin privileges can still install printer drivers on the client through other means, such as copying packaged drivers from a known good package location. Only the automatic download and installation processes are impacted by this issue.

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

Installation of printers using Internet Printing Protocol (IPP) might not complete successfully.

Note IPP is not commonly used by devices designed for home use. The 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.

If you want to remove the LCU

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.
