Version:

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.

Improvements

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

  • Addresses an issue that leads to User Datagram Protocol (UDP) packet drops from Linux virtual machines (VMs).

  • Updates daylight saving time (DST) in Chile to start on September 11, 2022 instead of September 4, 2022.

  • Addresses a known issue in which file copies which use Group Policy Preferences might fail or might create empty shortcuts or files that have 0 (zero) bytes.

For more information about the resolved security vulnerabilities, please refer to the Deployments | Security Update Guide and the October 2022 Security Updates.

Known issues in this update

Symptoms

Next step

On October 5, 2022, the Jordanian government made an official announcement ending the winter-time Daylight Saving Time (DST) time zone change. Starting at 12:00 a.m. Friday, October 28, 2022, the official time will not advance by an hour and will permanently shift to the UTC + 3 time zone. 

The impact of this change is as follows: 

  1. Clocks will not be advanced by an hour at 12:00 a.m. on October 28, 2022 for the Jordan time zone.

  2. The Jordan time zone will permanently shift to the UTC + 3 time zone.

Symptoms if no update is installed and the workaround is not used on devices in the Jordan time zone on October 28, 2022 or later:

  • 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 using 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 Jordan might also be affected if they are connecting to servers or devices in Jordan or if they are scheduling or attending meetings taking place in Jordan from another location or time zone. Windows devices outside of Jordan should not use the workaround, as it would change their local time on the device.

This issue is addressed in KB5020010. This update will not install automatically. To apply this update, you can check for updates and select the optional preview to download and install.

If you cannot install this update, you can mitigate this issue on devices in Jordan by doing either of the following on October 28, 2022:

  • Select the Windows logo key, type Date and time, and select Date and time settings. From the Date & time settings page, clear the Adjust for daylight saving time automatically check box.

  • Go to Control Panel > Clock and Region > Date and Time > Change time zone and clear the Automatically adjust clock for Daylight Saving Time check box.

Important We recommend using ONLY the above workaround to mitigate the issue with time created by the new Daylight Savings Time in Jordan. We do NOT recommend using any other workaround, as they can create inconsistent results and might create serious issues if done incorrectly.

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.

We have added guidance to KB5020276 and are evaluating whether optimizations can be made in a future Windows Update. This guidance will be updated as soon as those changes are released.

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 (KB5018922) 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 (KB5018413).

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.
