KB5055173: Overview with user sentiment and feedback

Overview

This is a Security and Quality Rollup update for .NET Framework 4.8 on Windows Server 2012 R2, scheduled for release on April 8, 2025. The update includes cumulative security and reliability improvements. It's important to note that this update comes after Windows Server 2012 R2 reached its end of support on October 10, 2023, though Extended Security Updates (ESUs) are available for purchase through October 13, 2026.

General Purpose

The update focuses on addressing two main areas: Windows Presentation Foundation (WPF) printing functionality and System.IO APIs operations. For WPF, it resolves an OutOfMemory exception issue that occurred when printing large numbers of pages. The update also improves the reliability of System.IO APIs when operating on files and directories on UNC shares. This maintenance release aims to enhance system stability and performance while ensuring continued compatibility with existing applications.

General Sentiment

The sentiment around this update appears generally positive, as it addresses specific functional issues without introducing major changes that could impact system stability. The improvements to printing functionality and file operations are welcome fixes for enterprise environments. However, organizations should note that this update comes after the end-of-support date for Windows Server 2012 R2, meaning they should be planning their migration strategy to newer supported versions of Windows Server.

Known Issues

• Installation may fail on Azure Arc-enabled devices running Windows Server 2012 R2
• Users must ensure all Subset of endpoints for ESU requirements are met for successful installation
