KB5055173: Overview with user sentiment and feedback

Overview

This is an April 2025 Security and Quality Rollup update for .NET Framework 4.8 on Windows Server 2012 R2. The update includes cumulative security and reliability improvements. This update is part of Microsoft's extended security update (ESU) program, as Windows Server 2012 R2 reached end of support on October 10, 2023.

General Purpose

The update addresses 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 System.IO APIs improvement focuses on operations involving files and directories on UNC shares. The update is cumulative, containing all previously released security improvements.

General Sentiment

The sentiment around this update appears generally positive as it addresses specific functional issues without introducing major changes. The update is particularly important for organizations still running Windows Server 2012 R2 under the ESU program. The improvements to WPF printing and UNC share operations address common enterprise scenarios.

Known Issues

• Installation may fail on Azure Arc-enabled devices running Windows Server 2012 R2
• Users must verify Subset of endpoints for ESU requirements before installation
