Microsoft has released its Patch Tuesday updates for Windows 7 (KB5021291) and Windows 8.1 (KB5021294) for December 2022. They both contain pretty much the same improvements, however, the Windows 8.1 notes do not list any known issues. It’s important to note that only Windows 7 users who have purchased extended security update (ESU) support will receive the update.
Improvements (applies to Windows 7 and Windows 8.1)
This security-only update includes new improvements for the following issue:
- By order of the Fijian government, Fiji will not observe daylight saving time (DST) in 2022. Therefore, clocks do not change by an hour at 02:00 on November 13, 2022.
- A memory leak in the Local Security Authority Subsystem Service (LSASS.exe) occurs on Windows domain controllers. This issue is known to occur after installing Windows updates dated November 8, 2022, or later.
For more information about the resolved security vulnerabilities, please refer to the Deployments | Security Update Guide and the August 2022 Security Updates.

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. |

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. The EMS System encountered a problem. To decide whether you are using an affected app, open the app which connects to a database.

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