Learn more about this cumulative security update, including improvements, any known issues, and how to get the update.
REMINDER Windows 7, Windows Server 2008 R2, Windows Embedded Standard 7, and Windows Embedded POS Ready 7 have reached the end of mainstream support and are now in extended security update (ESU) support. Windows Thin PC has reached the end of mainstream support; however, ESU support is not available. Starting in July 2020, there will no longer be optional, non-security releases (known as “C” 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 in the How to get this update section before installing this update. Customers who have purchased the Extended Security Update (ESU) for on-premises versions of this OS must follow the procedures in KB4522133 to continue receiving security updates after extended support ended on January 14, 2020. For more information about ESU and which editions are supported, see KB4497181. Because ESU is available as a separate SKU for each of the years in which they are offered (2020, 2021, and 2022)—and because ESU can only be purchased in specific 12-month periods—you must purchase the third year of ESU coverage separately and activate a new key on each applicable device for your devices to continue receiving security updates in 2022.If your organization did not purchase the third year of ESU coverage, you must purchase Year 1, Year 2, and Year 3 ESU for your applicable Windows 7 SP1 or Windows Server 2008 R2 SP1 devices before you install and activate the Year 3 MAK keys to receive updates. The steps to install, activate, and deploy ESUs are the same for first, second, and third year coverage. For more information, see Obtaining Extended Security Updates for eligible Windows devices for the Volume Licensing process and Purchasing Windows 7 ESUs as a Cloud Solution Provider for the CSP process. For embedded devices, contact your original equipment manufacturer (OEM).For more information, see the ESU blog.
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 for Windows 7 and Windows Server 2008 R2, see the following update history home page.
This cumulative security update contains improvements that are part of update KB5017361 (released September 13, 2022) and includes key changes for the following:
Symptom | Next step |
---|---|
After installing this update and restarting your device, you might receive the error, “Failure to configure Windows updates. Reverting Changes. Do not turn off your computer”, and the update might show as Failed inUpdate History. | This is expected in the following circumstances: |
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 KB5020000. 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, typeDate and time, and selectDate and time settings. From theDate & time settingspage, clear theAdjust for daylight saving time automatically check box.
Go to Control Panel >Clock and Region>Date and Time>Change time zoneand clear theAutomatically adjust clock for Daylight Saving Timecheck 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.| Please see KB5020276 for guidance on this issue.
After installing this update, some types of Secure Sockets Layer (SSL) and Transport Layer Security (TLS) connections might have handshake failures.Note for developers: Affected connections might send multiple frames in a single input buffer. Specifically, one or more complete records with a partial record that is less than 5 bytes might be sent in a single buffer.When encountering this issue, your app will receive SEC_E_ILLEGAL_MESSAGE when the connection fails.| To address this issue, install update KB5020447. Then, we recommend that you install the latest security update for your device.Note Update KB5020447 will not install automatically. To apply this update, check for updates and then choose the Optional update to download and install.
