KB5058451: Overview with user sentiment and feedback

Overview

KB5058451 is a Monthly Rollup update for Windows Server 2012 released on May 13, 2025. This Extended Security Update (ESU) is part of Microsoft's continued support for Windows Server 2012 systems that have purchased extended support, as the base operating system reached end of support on October 10, 2023. ESU support will continue until October 2026, providing critical security updates for organizations that need additional time to complete their migration plans.

General Purpose

This update includes security improvements focused on enhancing the Secure Boot Advanced Targeting (SBAT) capabilities for Linux system detection. The update builds upon previous security improvements from KB5055581 released in April 2025. The patch is particularly important for maintaining system security and ensuring proper system operation, especially in environments where Linux systems may be present alongside Windows Server installations.

General Sentiment

The general sentiment towards this update appears positive, with no major issues reported in the initial rollout. However, there is a notable installation consideration for Azure Arc-enabled devices running Windows Server 2012, where the update might fail to install unless specific endpoint requirements are met. Organizations should carefully review the Connected Machine agent network requirements before proceeding with installation.

Known Issues

• Installation may fail on Azure Arc-enabled devices running Windows Server 2012 unless specific endpoint requirements are met
• Latest Servicing Stack Update (SSU KB5058530) must be installed before this update can be installed
• Language packs installed after this update will require the update to be reinstalled
