KB5055581: Overview with user sentiment and feedback

Overview

KB5055581 is the April 2025 Monthly Rollup update for Windows Server 2012 Extended Security Update (ESU) customers. This update is part of Microsoft's ongoing commitment to provide security and reliability improvements to supported Windows Server platforms. The update is specifically designed for Windows Server 2012 systems that are enrolled in the Extended Security Update program, which provides critical security updates beyond the standard end of support date.

General Purpose

This monthly rollup includes security improvements and addresses vulnerabilities in Windows Server 2012. A notable security enhancement involves changes to the system folder structure, specifically the creation of a new %systemdrive%inetpub folder that enhances system protection. The update also incorporates previous security improvements from KB5053886 released in March 2025. This patch is particularly important for maintaining the security posture of Windows Server 2012 systems that are still in operation beyond the standard support lifecycle.

General Sentiment

The general sentiment toward this update appears to be neutral to positive. The update is straightforward in its implementation, though there are some specific requirements that administrators need to be aware of. The most notable consideration is the requirement to have the latest Servicing Stack Update (SSU) installed before this update can be applied. For Azure Arc-enabled devices, there are additional prerequisites regarding endpoint connectivity that need to be verified for successful installation.

Known Issues

• Installation may fail on Azure Arc-enabled devices running Windows Server 2012 if specific endpoint requirements are not met
• A new %systemdrive%inetpub folder will be created after installation - this is expected behavior and should not be deleted
• Language packs must be reinstalled if they are installed after this update
