Security-only update

Summary

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

REMINDER Windows 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.

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, see the Windows 8.1 and Windows Server 2012 R2 update history home page.

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 KB5018476.

After installing this update, file copies which use Group Policy Preferences might fail or might create empty shortcuts or files that have 0 (zero) bytes. Known affected Group Policy Objects are related to files and shortcuts in User Configuration > Preferences > Windows Settings in Group Policy Editor.

This issue is resolved in update KB5018476. If any workaround was used to mitigate this issue, we recommend that you revert to your original configuration.

How to get this update

Before installing this update

We strongly recommend that you install the latest servicing stack update (SSU) for your operating system before you install the latest Rollup. SSUs improve the reliability of the update process to mitigate potential issues while installing the Rollup and applying Microsoft security fixes. For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

If you use Windows Update, the latest SSU (KB5017398) will be offered to you automatically. To get the standalone package for the latest SSU, search for it in the Microsoft Update Catalog

REMINDER If you are using Security-only updates, you will also need to install all previous Security-only updates and the latest cumulative update for Internet Explorer (KB5016618).

Language packs

If you install a language pack after you install this update, you must reinstall this update. Therefore, we recommend that you install any language packs that you need before you install this update. For more information, see Add language packs to Windows.
