November 8, 2022—KB5020013 (Security-only update)

NOTE After January 10, 2023, Microsoft will no longer provide security updates or technical support for Windows 7 SP1 and Windows Server 2008 R2 SP1. We recommend that you upgrade to a later version of Windows.

Summary

Learn more about this security-only update, including improvements, any known issues, and how to get the update.

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 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 this OS must follow the procedures in KB4522133 to continue receiving security updates after extended support ended on January 14, 2020. For more information about 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.

Note For information about the various types of Windows updates, such as critical, security, driver, service packs, and so on, please see the following article. To view other notes and messages for Windows 7 SP1 and Windows Server 2008 R2 SP1, see the following update history home page.

Improvements

This security-only update includes key changes for the following:

Updates the daylight-saving time (DST) for Jordan to prevent moving the clock back 1 hour on October 28, 2022. Additionally, changes the display name of Jordan standard time from “(UTC+02:00) Amman” to “(UTC+03:00) Amman”.
Addresses an issue where, after installing the January 11, 2022 or later update, the Forest Trust creation process fails to populate the DNS name suffixes into the trust information attributes.
Addresses security vulnerabilities in the Kerberos and Netlogon protocols as outlined in CVE-2022-38023, CVE-2022-37966, and CVE-2022-37967. For deployment guidance, see the following articles:

Known issues in this update

Symptom

Next step

After installing this update and restarting your device, you might receive the error, “Failure to configure Windows updates. Reverting Changes. Do not turn off your computer,” and the update might show as Failed in Update History.

This is expected in the following circumstances:

If you are installing this update on a device that is running an edition that is not supported for ESU. For a complete list of which editions are supported, see KB4497181.
If you do not have an ESU MAK add-on key installed and activated.
If you have purchased an ESU key and have encountered this issue, please verify you have applied all prerequisites and that your key is activated. For information on activation, please see this blog post. For information on the prerequisites, see the How to get this update section of this article.

After this update or a later Windows update is installed, domain join operations might be unsuccessful and error "0xaac (2732): NERR_AccountReuseBlockedByPolicy" occurs. Additionally, text stating "An account with the same name exists in Active Directory. Re-using the account was blocked by security policy" might be displayed.

Affected scenarios include some domain join or re-imaging operations where a computer account was created or pre-staged by a different identity than the identity used to join or re-join the computer to the domain.

For more information about this issue, see KB5020276—Netjoin: Domain join hardening changes.

Note Consumer Desktop editions of Windows are unlikely to experience this issue.

Please see KB5020276 for guidance on this issue.

After installing Windows updates released on or after November 8, 2022 on Windows Servers that use the Domain Controller role, you might have issues with Kerberos authentication. This issue might affect any Kerberos authentication in your environment. Some scenarios which might be affected:

Domain user sign in might fail. This might also affect Active Directory Federation Services (AD FS) authentication.
Group Managed Service Accounts (gMSA) used for services such as Internet Information Services (IIS Web Server) might fail to authenticate.
Remote Desktop connections using domain users might fail to connect.
You might be unable to access shared folders on workstations and file shares on servers.
Printing that requires domain user authentication might fail.

When this issue is encountered you might receive a Microsoft-Windows-Kerberos-Key-Distribution-Center Event ID 4 error event in the System section of the event log on your Domain Controller with the below text.

Note Affected events will contain "the missing key has an ID of 1" string:

While processing an AS request for target service <service>, the account <account name> did not have a suitable key for generating a Kerberos ticket (the missing key has an ID of 1). The requested etypes : 18 3. The accounts available etypes : 23 18 17. Changing or resetting the password of <account name> will generate a proper key.

Note This issue is not an expected part of the security hardening for Netlogon and Kerberos starting with November 2022 security update. You will still have to follow the guidance in these articles even after this issue is resolved.

Windows devices used at home by consumers or devices which are not part of an on-premises domain are not affected by this issue. Azure Active Directory environments that are not hybrid and have no on-premises Active Directory servers are not affected.

This issue is addressed in update KB5021651.

After installing this update or a later update on a domain controller (DC), you might experience a memory leak with the Local Security Authority Subsystem Service (LSASS,exe). Depending on the workload of your DC and the amount of time since the last restart of the server, LSASS might continually increase memory usage with the up time of the server and the server might become unresponsive or automatically restart.

Note The out-of-band updates for DCs released November 17, 2022 and November 18, 2022 might be affected by this issue.

To mitigate this issue, open a Command Prompt as an Administrator and use the following command to set the registry key KrbtgtFullPacSignature to 0:

reg add "HKLM\System\CurrentControlSet\services\KDC" -v "KrbtgtFullPacSignature" -d 0 -t REG_DWORD

Note After this known issue is resolved, you should set KrbtgtFullPacSignature to a higher setting, depending on what your environment will allow. We recommend that you enable Enforcement mode as soon as your environment is ready.

For more information about this registry key, please see KB5020805: How to manage Kerberos protocol changes related to CVE-2022-37967.

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

After installing this update, apps which use ODBC connections through Microsoft ODBC SQL Server Driver (sqlsrv32.dll) to access databases might not connect. Additionally, you might receive an error in the app, or you might receive an error from the SQL Server. Errors you might receive include the following messages:

The EMS System encountered a problem. Message: [Microsoft][ODBC SQL Server Driver] Protocol error in TDS Stream.
The EMS System encountered a problem. Message: [Microsoft][ODBC SQL Server Driver] Unknown token received from SQL Server.

Note for developers: Apps affected by this issue might fail to fetch data, for example when using the SQLFetch function. This issue might occur when calling SQLBindCol function before SQLFetch or calling SQLGetData function after SQLFetch and when a value of 0 (zero) is given for the ‘BufferLength’ argument for fixed datatypes larger than 4 bytes (such as SQL_C_FLOAT).

To decide whether you are using an affected app, open the app which connects to a database. Open a Command Prompt window, type the following command and then press Enter:

tasklist /m sqlsrv32.dll

If the command returns a task, then the app might be affected.

To mitigate this issue, you can do one of the following:

If your app is already using or able to use Data Source Name (DSN) to select ODBC connections, install Microsoft ODBC Driver 17 for SQL Server and select it for use with your app using DSN.Note: We recommend the latest version of Microsoft ODBC Driver 17 for SQL Server, as it is more compatible with apps currently using the legacy Microsoft ODBC SQL Server Driver (sqlsrv32.dll) than Microsoft ODBC Driver 18 for SQL Server.
If your app is unable to use DSN, the app will need to be modified to allow for DSN or to use a newer ODBC driver than Microsoft ODBC SQL Server Driver (sqlsrv32.dll).

This issue was resolved in KB5022339. If you have implemented the above workaround, it is recommended to continue using the configuration in the workaround.
