Starting in July 2020, there will no longer be optional releases (known as "C" or "D" 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. **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](<https://support.microsoft.com/help/824684>). To view other notes and messages, see the Windows Server 2012 update history [home page](<https://support.microsoft.com/help/4009471>). ## **Improvements** This cumulative security update contains improvements that are part of update [KB5016672](<https://support.microsoft.com/help/5016672>) (released August 9, 2022) and includes key changes for the following issue: * This update contains miscellaneous security improvements to internal OS functionality. No specific issues are documented for this release. For more information about the resolved security vulnerabilities, please refer to the [Deployments | Security Update Guide](<https://msrc.microsoft.com/update-guide/deployments>) and the [September 2022 Security Updates](<https://msrc.microsoft.com/update-guide/releaseNote/2022-Sep>). ## **Known issues in this update** **Symptoms**| **Next step** ---|--- Starting at 12:00 A.M. Saturday, September 10, 2022, the official time in Chile will advance 60 minutes in accordance with the August 9, 2022 official announcement by the Chilean government about a daylight saving time (DST) time zone change. This moves the DST change which was previously September 4 to September 10.Symptoms if the workaround is not used on devices between September 4, 2022 and September 11, 2022: * ​Time shown in Windows and apps will not be correct. * ​Apps and cloud services which use date and time for integral functions, such as Microsoft Teams and Microsoft Outlook, notifications and scheduling of meetings might be 60 minutes off. * ​Automation that uses date and time, such as Scheduled tasks, might not run at the expected time. * ​Timestamp on transactions, files, and logs will be 60 minutes off. * ​Operations that rely on time-dependent protocols such as Kerberos might cause authentication failures when attempting to logon or access resources. * ​Windows devices and apps outside of Chile might also be affected if they are connecting to servers or devices in Chile or if they are scheduling or attending meetings taking place in Chile from another location or time zone. Windows devices outside of Chile should not use the workaround, as it would change their local time on the device. | This issue is resolved in update [KB5018457](<https://support.microsoft.com/help/5018457>). After installing this update, file copies which use [Group Policy Preferences](<https://learn.microsoft.com/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/dn581922\(v=ws.11\)>) might fail or might create empty shortcuts or files that have 0 (zero) bytes.
