This is an Extended Security Update (ESU) that includes security improvements and fixes from the previous month's update KB5055581. The update is part of the extended support phase for Windows Server 2012, which reached end of standard support in October 2023 but continues to receive security updates through ESU until October 2026.

General Purpose

The primary purpose of this update is to enhance system security and functionality for Windows Server 2012 systems. A key improvement focuses on the Secure Boot Advanced Targeting (SBAT) system, specifically enhancing the detection capabilities for Linux systems. The update also includes cumulative security fixes from previous updates, ensuring continued protection for systems enrolled in the Extended Security Update program.

General Sentiment

The general sentiment towards this update appears positive, with no major issues reported in the initial deployment. However, there is a notable installation consideration for Azure Arc-enabled devices running Windows Server 2012, where the update might fail to install without proper endpoint configuration. Microsoft has provided clear guidance for ensuring successful installation on these systems by following the Connected Machine agent network requirements.

Known Issues
