KB5061978: Overview with user sentiment and feedback

Overview

This is an out-of-band update (OS Build 17763.7322) released on May 27, 2025, that includes security and quality improvements from the previous update KB5058392 (released May 13, 2025). The update primarily addresses issues affecting Windows 10 Enterprise LTSC 2019, Windows 10 IoT Enterprise LTSC 2019, Windows 10 IoT Core LTSC, and Windows Server 2019.

This update is particularly significant as it addresses critical functionality issues in the Hyper-V Platform, specifically focusing on problems affecting confidential virtual machines running on Windows Server 2022.

General Purpose

The primary purpose of this update is to resolve a critical issue in the Hyper-V Platform's direct send path for guest physical addresses (GPA). The issue was causing confidential virtual machines running on Hyper-V with Windows Server 2022 to intermittently stop responding or restart unexpectedly, affecting service availability and requiring manual intervention. This problem particularly impacted Azure confidential VMs.

The update also includes the latest servicing stack update (SSU) combined with the latest cumulative update (LCU) to improve the reliability of the update process and mitigate potential installation issues. The servicing stack is the component responsible for installing Windows updates, and these improvements help ensure more reliable update installations.

General Sentiment

The sentiment towards this update appears generally positive as it addresses a specific and significant issue affecting virtual machine stability and service availability in enterprise environments. The fact that it's released as an out-of-band update indicates its importance and urgency in addressing the Hyper-V platform issues.

The inclusion of servicing stack improvements also suggests Microsoft's continued commitment to improving the update process itself. However, as with any out-of-band update, some caution is warranted during deployment, particularly in production environments.
