KB5055521: Overview with user sentiment and feedback

Overview

KB5055521 is a cumulative security and quality improvement update for Windows 10 version 1607 and Windows Server 2016. Released on April 8, 2025, this update includes important security patches and system improvements. The update addresses Daylight Saving Time (DST) changes for the Aysen region in Chile and implements important security enhancements to the operating system.

General Purpose

This update serves multiple purposes including implementing critical security improvements for the Windows operating system. It includes a DST update for Chile's Aysen region to support government-mandated time zone changes in 2025. The update also creates a new %systemdrive%inetpub folder as part of security enhancements, which should not be deleted regardless of IIS installation status. This change is part of broader security improvements and requires no action from IT administrators or end users.

General Sentiment

The general sentiment towards this update appears cautious but positive. The update primarily focuses on security improvements and time zone adjustments, which are typically low-risk changes. However, there is a known issue affecting Active Directory Group Policy audit settings that may impact enterprise environments. While this issue doesn't affect the core functionality of security auditing, it may cause reporting inconsistencies in enterprise settings. Home users are unlikely to be affected by the reported issues.

Known Issues

• Active Directory Group Policy audit settings may display incorrectly in Local Group Policy Editor
• Logon/Logoff audit events might show as disabled even when enabled and working
• The issue affects only the display of audit settings and not their actual functionality
• A fix is available in KB5058921 (OS Build 14393.7973) Out-of-band update
