KB5055581: Overview with user sentiment and feedback

Overview

KB5055581 is a Monthly Rollup update for Windows Server 2012 released on April 8, 2025. This update is part of Microsoft's Extended Security Update (ESU) program for Windows Server 2012, which reached end of support on October 10, 2023. The ESU program will continue providing critical security updates until October 13, 2026, requiring an annual subscription renewal.

General Purpose

This cumulative security update includes important security improvements and fixes from previous updates (KB5053886). The update addresses vulnerabilities in Windows Server 2012, particularly focusing on OS Security and Kerberos Authentication. A key security enhancement involves the creation of an inetpub folder for increased system protection, and improvements to certificate authority handling in Windows root store and NTAuth store interactions.

General Sentiment

The update appears to be a standard monthly security rollup with clear documentation and implementation requirements. Microsoft has provided detailed installation prerequisites, notably requiring the latest Servicing Stack Update (KB5055667) before installation. The changes seem focused on strengthening system security without introducing significant operational changes.

Known Issues

• No known issues have been reported with this update at the time of release
• Installation may fail on Azure Arc-enabled devices running Windows Server 2012
• Requires latest SSU (KB5055667) to be installed first
