MC447316: Take action: Out-of-band update to address issues after installing the October 2022 Windows security updates

Microsoft is releasing Out-of-band updates today, October 17, 2022, for some versions of Windows. This update addresses a known issue that might cause SSL/TLS handshakes to fail.

All versions are available only on the Microsoft Update Catalog and will not be offered through Windows Update. For instructions, see the release notes for your OS listed below. Note: Organizations can manually import these updates into Windows Server Update Services (WSUS) and Microsoft Endpoint Configuration Manager.

Cumulative updates:

  • Windows 11, version 21H2: KB5020387
  • Windows Server 2022: KB5020436
  • Windows 10, version 20H2; Windows 10, version 21H1; Windows 10, version 22H1; Windows 10 Enterprise LTSC 2021: KB5020435
  • Windows 10 Enterprise LTSC 2019; Windows Server 2019: KB5020438
  • Windows 10 2016 LTSB; Windows Server 2016: KB5020439
  • Windows 10 2015 LTSB; KB5020440

Note: You do not need to apply any previous update before installing these cumulative updates.

Standalone Updates:

Note: If you are using security only updates for these versions of Windows Server, you only need to install these standalone updates for the month of October 2022. Security only updates are not cumulative, and you will also need to install all previous Security only updates to be fully up to date. Monthly rollup updates are cumulative and include security and all quality updates. If you are normally using Monthly rollup updates, you will need to install both the standalone updates listed above to resolve this issue, and install the Monthly rollups released October 11, 2022 to receive the quality updates for October 2022.
