Note

REMINDERWindows 8.1 will reach end of support on January 10, 2023, at which point technical assistance and software updates will no longer be provided. If you have devices running Windows 8.1, we recommend upgrading them to a more current, in-service, and supported Windows release. If devices do not meet the technical requirements to run a more current release of Windows, we recommend that you replace the device with one that supports Windows 11.
Microsoft will not be offering an Extended Security Update (ESU) program for Windows 8.1. Continuing to use Windows 8.1 after January 10, 2023 may increase an organization’s exposure to security risks or impact its ability to meet compliance obligations.
For more information, see Windows 8.1 support will end on January 10, 2023.
Windows Server 2012 R2 will reach end of support on October 10, 2023 for Datacenter, Essentials, Embedded Systems, Foundation, and Standard.

Improvements

This cumulative security update includes improvements that are part of update KB5021294 (released December 13, 2022). This update also makes improvements for the following issues:

Authentication might fail after you set the higher 16-bits of the msds-SupportedEncryptionTypes attribute. This issue might occur if encryption types are not set or if RC4 Encryption type is disabled on the domain.
Starting in this release, we are displaying a modal dialog box to remind users about the End of Support for Windows 8.1 in January 2023. This reminder does not appear on managed devices that run Windows 8.1 Pro or Windows 8.1 Enterprise.
Resolves a known issue that affects apps that use Microsoft Open Database Connectivity (ODBC) SQL Server Driver (sqlsrv32.dll) to connect to databases. The connection might fail. You might also receive an error in the app, or you might receive an error from the SQL Server.

For more information about the resolved security vulnerabilities, please refer to the Deployments | Security Update Guide and the January 2023 Security Updates.

Known issues in this update

Symptom

Next step

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.

This issue is resolved in KB5023765.
