KB5055557: Overview with user sentiment and feedback

Overview

KB5055557 is the April 2025 Monthly Rollup update for Windows 8.1 and Windows Server 2012 R2. This is an Extended Security Update (ESU) release, as Windows Server 2012 R2 reached end of support in October 2023. The update includes important security improvements and Daylight Saving Time (DST) changes for specific regions.

General Purpose

The update serves multiple purposes including implementing Daylight Saving Time changes for the Aysen region in Chile to comply with government DST orders for 2025. It also includes security improvements related to system protection, specifically creating a new %systemdrive%inetpub folder as part of enhanced security measures. This update requires the latest Servicing Stack Update (SSU) KB5055665 to be installed first before it can be deployed.

General Sentiment

The sentiment around this update appears generally positive, with no major issues reported. However, there are some implementation requirements that administrators should be aware of, particularly the prerequisite of installing the latest SSU before this update can be applied. For Azure Arc-enabled devices running Windows Server 2012 R2, there may be installation challenges that require ensuring all Subset of endpoints for ESU requirements are met.

Known Issues

• Installation may fail on Azure Arc-enabled devices running Windows Server 2012 R2 unless specific endpoint requirements are met
• A new %systemdrive%inetpub folder will be created after installation (by design, not an issue)
• Language packs must be installed before this update to avoid reinstallation requirements
