Learn more about this cumulative security update, including improvements, any known issues, and how to get the update.
IMPORTANT Windows Server 2008 Service Pack 2 (SP2) has reached the end of mainstream support and is now in extended support. 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 Server 2008 SP2 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.
This cumulative security update contains improvements that are part of update KB5015866 (released July 12, 2022) and includes new improvements for the following issue:
Addresses an issue that might cause the Local Security Authority Server Service (LSASS) to leak tokens. This issue affects devices that have installed Windows updates dated June 14, 2022 or later. This issue occurs when the device performs a specific form of service for user (S4U) in a non-Trusted Computing Base (TCB) Windows service that runs as Network Service.
Enforces a hardening change that requires printers and scanners that use smart cards for authentication to have firmware that complies with section 3.2.1 of RFC 4556. If they do not comply, Active Directory domain controllers will not authenticate them. Mitigations that allowed non-compliant devices to authenticate will not exist after August 9, 2022. For more information about this change, see KB5005408.
Known issues in this update
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 in Update History.
This is expected in the following circumstances:
If you have purchased an ESU key and have encountered this issue, please verify you have applied all prerequisites and that your key is activated. For information on activation, please see this blog post. For information on the prerequisites, see the "How to get this update" section of this article.
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 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:
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 KB5018450.
