KB5055172: Overview with user sentiment and feedback

Overview

This is an Extended Security Update (ESU) for .NET Framework 4.8 on Windows Server 2012, released for April 8, 2025. The update is part of the ongoing security and quality rollup program for the .NET Framework. It's important to note that Windows Server 2012 reached end of support (EOS) on October 10, 2023, and this update is only available through the ESU program which will continue until October 13, 2026.

General Purpose

The update addresses several key areas in the .NET Framework 4.8. It includes improvements to Windows Presentation Foundation (WPF) printing functionality, specifically fixing issues with printing large numbers of pages that were previously causing OutOfMemory exceptions. The update also enhances System.IO APIs when operating on files and directories on UNC shares. This cumulative update contains all previously released security and reliability improvements.

General Sentiment

The sentiment around this update appears generally positive, as it addresses specific functional issues without introducing new security vulnerabilities. The update is particularly important for organizations still running Windows Server 2012 systems through the ESU program. The primary improvements focus on stability and reliability rather than security fixes, which suggests a mature and stable release.

Known Issues

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