REMINDER Windows 7, Windows Server 2008 R2, Windows Embedded Standard 7, and Windows Embedded POS Ready 7 have reached the end of mainstream support and are now in extended security update (ESU) support. Windows Thin PC has reached the end of mainstream support; however, ESU support is not available. 

Starting in July 2020, there will no longer be optional, non-security releases (known as "C" releases) for this operating system. Operating systems in extended support have only cumulative monthly security updates (known as the "B" or Update Tuesday release).

Verify that you have installed the required updates listed in the How to get this update section before installing this update. 

Customers who have purchased the Extended Security Update (ESU) for on-premises versions of these operating systems must follow the procedures in KB4522133 to continue receiving security updates after extended support ends on January 14, 2020. For more information on ESU and which editions are supported, see KB4497181.

Because ESU is available as a separate SKU for each of the years in which they are offered (2020, 2021, and 2022)—and because ESU can only be purchased in specific 12-month periods —you must purchase the third year of ESU coverage separately and activate a new key on each applicable device for your devices to continue receiving security updates in 2022.

If your organization did not purchase the third year of ESU coverage, you must purchase Year 1, Year 2, and Year 3 ESU for your applicable Windows 7 SP1 or Windows Server 2008 R2 SP1 devices before you install and activate the Year 3 MAK keys to receive updates. The steps to install, activate, and deploy ESUs are the same for first, second, and third year coverage. For more information, see Obtaining Extended Security Updates for eligible Windows devices for the Volume Licensing process and Purchasing Windows 7 ESUs as a Cloud Solution Provider for the CSP process. For embedded devices, contact your original equipment manufacturer (OEM).

For more information, see the ESU blog.

REMINDER Starting in August, 2019, updates to .NET Framework 4.6 and above, for Windows Server 2008 SP1, Windows Server 2008 R2 SP1, and Windows 7SP1, require SHA-2 Code signing support. Please make sure that you have all the latest Windows Updates before applying this update to avoid installation issues. For more detailed information about SHA-2 code signing support updates, please see KB 4474419.

Summary

The November 8, 2022 update for Windows 7 SP1 and Windows Server 2008 R2 SP1 includes cumulative reliability improvements in .NET Framework 4.8. We recommend that you apply this update as part of your regular maintenance routines. Before you install this update, see the How to get this update section.

Security Improvements

This security update addresses a vulnerability which exists in System.Data.SqlClient and Microsoft.Data.SqlClient libraries where a timeout occurring under high load can cause incorrect data to be returned as the result of an asynchronously executed query or command. For more information please see CVE-2022-41064.

Quality and Reliability Improvements

WPF1

- Addresses an issue where a FailFast crash could occur when using WebBrowser.NavigateToString.

- Addresses an ArgumentOutOfRangeException that can arise when calling ListBox.ScrollIntoView while there are pending changes to the visual tree that will change or clear the underlying ItemsCollection.

- Addresses an ArgumentException "Width and Height must be non-negative" that can arise in an ItemsControl with grouping enabled, custom margins on the GroupItems, collapse/expand of GroupItems enabled, and run in high-DPI.
