KB5055557: Overview with user sentiment and feedback

Overview

This is the April 2025 Monthly Rollup update for Windows Server 2012 R2. The update includes important security improvements and Daylight Saving Time (DST) changes for the Aysen region in Chile. This is an Extended Security Update (ESU) release, which means it's part of the paid extended support program for Windows Server 2012 R2 that continues until October 2026.

General Purpose

The update serves multiple purposes including implementing security enhancements and timezone adjustments. A key security improvement involves changes to the system drive's inetpub folder structure to increase protection. The update also includes DST changes for Chile's Aysen region to align with government requirements for 2025. Additionally, this update builds upon previous security improvements from KB5053887 released in March 2025.

General Sentiment

The general sentiment towards this update appears positive, with no major issues reported. The update is particularly important for organizations still running Windows Server 2012 R2 under the ESU program. However, users should note that this update requires the latest Servicing Stack Update (SSU KB5055665) to be installed first. The implementation of security improvements and timezone updates appears to be straightforward with no significant concerns raised in the available documentation.

Known Issues

• No known issues have been reported with this update as of release
• Installation may fail on Azure Arc-enabled devices running Windows Server 2012 R2 unless specific endpoint requirements are met
