How to get this update

Before installing this update

Windows Server 2008 Service Pack 2 (SP2) has reached the end of mainstream support and is now in extended support. 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.

To view other notes and messages for Windows Server 2008 SP2, see the following update history home page.

Monthly rollup updates are cumulative and include security and all quality updates. If you use Monthly rollup updates, you have to install both this update and the Monthly rollup released May 10, 2022 to receive the quality updates for May 2022. If you have already installed updates released May 10, 2022, you do not have to uninstall the affected update before you install any later updates including this update.

If you use Security-only updates for Windows Server, you only have to install this update for May 2022. Security-only updates are not cumulative, and you will also have to install all previous Security-only updates to be fully up to date.
