We recommend you install the latest security updates for your device. Customers installing Windows Server 2019 using media should install the latest [Servicing Stack Update (SSU)](<https://docs.microsoft.com/windows/deployment/update/servicing-stack-updates>) before installing the language pack or other optional components. If using the [Volume Licensing Service Center (VLSC)](<https://www.microsoft.com/licensing/servicecenter/default.aspx>), acquire the latest Windows Server 2019 media available. The proper order of installation is as follows: 1. Install the latest prerequisite SSU, currently [KB5005112](<https://support.microsoft.com/help/5005112>) 2. Install optional components or language packs 3. Install latest cumulative update **Note** Updating your device will prevent this issue, but will have no effect on devices already affected by this issue. If this issue is present in your device, you will need to use the workaround steps to repair it.**Workaround:** 1. Uninstall and reinstall any recently added language packs. For instructions, see [Manage the input and display language settings in Windows 10](<https://support.microsoft.com/windows/manage-the-input-and-display-language-settings-in-windows-12a10cb4-8626-9b77-0ccb-5013e0c7c7a2>). 2.

For instructions, see [Update Windows 10](<https://support.microsoft.com/windows/update-windows-3c5ae7fc-9fb6-9af1-1984-b5e0412c556a>). **Note **If reinstalling the language pack does not mitigate the issue, use the In-Place-Upgrade feature. For guidance, see [How to do an in-place upgrade on Windows](<https://docs.microsoft.com/troubleshoot/windows-server/deployment/repair-or-in-place-upgrade>), and [Perform an in-place upgrade of Windows Server](<https://docs.microsoft.com/windows-server/get-started/perform-in-place-upgrade>). After installing KB5001342 or later, the Cluster Service might fail to start because a Cluster Network Driver is not found.| This issue occurs because of an update to the PnP class drivers used by this service. After about 20 minutes, you should be able to restart your device and not encounter this issue. For more information about the specific errors, cause, and workaround for this issue, please see KB5003571. After installing this update, the Encrypted File System (EFS) API [OpenEncryptedFileRaw(A/W)](<https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-openencryptedfilerawa>), often used in backup software, will not work when you back up to or from a Windows Server 2008 SP2 device. OpenEncryptedFileRaw will continue to work on all other versions of Windows (local and remote).| This behavior is expected because we addressed the issue in CVE-2021-36942.**Note** If you cannot use backup software on Windows 7 SP1 and Server 2008 R2 SP1 or later after installing this update, contact the manufacturer of your backup software for updates and support. After installing updates released April 22, 2021 or later, an issue occurs that affects versions of Windows Server that are in use as a Key Management Services (KMS) host. Client devices running Windows 10 Enterprise LTSC 2019 and Windows 10 Enterprise LTSC 2016 might fail to activate. This issue only occurs when using a new Customer Support Volume License Key (CSVLK). **Note** This does not affect activation of any other version or edition of Windows. Client devices that are attempting to activate and are affected by this issue might receive the error, "Error: 0xC004F074. The Software Licensing Service reported that the computer could not be activated. No Key Management Service (KMS) could be contacted. Please see the Application Event Log for additional information."Event Log entries related to activation are another way to tell that you might be affected by this issue. Open **Event Viewer **on the client device that failed activation and go to **Windows Logs **> **Application**. If you see only event ID 12288 without a corresponding event ID 12289, this means one of the following: * The KMS client could not reach the KMS host. * The KMS host did not respond. * The client did not receive the response. For more information on these event IDs, see [Useful KMS client events - Event ID 12288 and Event ID 12289](<https://docs.microsoft.com/windows-server/get-started/activation-troubleshoot-kms-general#event-id-12288-and-event-id-12289>).| This issue is resolved in KB5009616. ## How to get this update **Before installing this update**Prerequisite:You **must **install the May 11, 2021 servicing stack update (SSU) (KB5003243) or the latest SSU (KB5005112) before installing the latest cumulative update (LCU).
