Highlights

  • Updates an issue that might prevent printers, scanners, and multifunction devices from working. This issue occurs on devices that do not comply with a certain specification and use smart card authentication. 

Improvements and fixes

This non-security update includes quality improvements. Key changes include:

  • Temporarily addresses an issue with devices that do not comply with section 3.2.1 of the RFC 4556 specification, which is required for CVE-2021-33764. Noncompliant printers, scanners, and multifunction devices might not work when you use smart card authentication (PIV). You must enable this temporary mitigation using a registry key. Otherwise, this issue will occur after you install the July 13, 2021 or later update on domain controllers (DC) in your environment.

    Important You must have your noncompliant devices updated and compliant or replaced by February 8, 2022. After that, the mitigation will not work in security updates. For more information, see KB5005408.

If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.

Windows Update Improvements

Microsoft has released an update directly to the Windows Update client to improve reliability. Any device running Windows 10 configured to receive updates automatically from Windows Update, including Enterprise and Pro editions, will be offered the latest Windows 10 feature update based on device compatibility and Windows Update for Business deferral policy. This doesn't apply to long-term servicing editions.

Known issues in this update

Symptom

Workaround

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.

This issue is resolved in KB5010359.

How to get this update

Before installing this update

Microsoft strongly recommends you install the latest servicing stack update (SSU) for your operating system before installing the latest cumulative update (LCU). SSUs improve the reliability of the update process to mitigate potential issues while installing the LCU and applying Microsoft security fixes. For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.
