KB5062553: Overview with user sentiment and feedback

Overview

KB5062553 is a security update released on July 8, 2025, for Windows 11 version 24H2 (OS Build 26100.4652). This mandatory security patch addresses multiple vulnerabilities and includes improvements previously introduced in the June 2025 non-security update (KB5060829). The update focuses on enhancing system security while also fixing several functional issues related to graphics, multimedia, and Windows Firewall. The update is part of Microsoft's regular Patch Tuesday release cycle and contains fixes for 137 security flaws, including one zero-day vulnerability (CVE-2025-49719) that has been actively exploited in the wild. This particular vulnerability affects Microsoft SQL Server and could lead to information disclosure. While Microsoft has assessed the exploitability of this vulnerability as less likely, its public disclosure and confirmed exploitation make it a significant security concern. In addition to security patches, KB5062553 updates several AI components for Windows Copilot+ PCs, including Image Search, Content Extraction, and Semantic Analysis, all updated to version 1.2506.707.0. The update also includes a Windows 11 servicing stack update (KB5063666 - version 26100.4651) that improves the component responsible for installing Windows updates.

General Purpose

The primary purpose of KB5062553 is to address critical security vulnerabilities in Windows 11 version 24H2. It patches 137 security flaws, including a zero-day vulnerability in Microsoft SQL Server that has been exploited in the wild. This makes the update essential for maintaining system security and protecting against potential threats. Beyond security fixes, the update resolves several functional issues that were affecting user experience. It fixes a graphics issue where game content would become out of sync with cursor position after using ALT+Tab to switch between applications when game resolution doesn't match desktop resolution. It addresses a multimedia problem where notification sounds weren't playing for on-screen alerts, volume adjustments, and sign-in events. The update also tackles a Windows Firewall issue that was causing Event 2042 errors in Event Viewer with "Config Read Failed" and "More data is available" messages. For Windows Copilot+ PCs, the update refreshes AI components including Image Search, Content Extraction, and Semantic Analysis to version 1.2506.707.0. Additionally, it includes improvements to the Copilot key functionality, enhancing its reliability and fixing an issue where users couldn't restart Copilot after using the key. The update also introduces a redesigned Accessibility menu in Quick Settings for improved clarity and usability, with text descriptions for assistive technologies like Narrator and Voice access.

General Sentiment

The general sentiment toward KB5062553 appears to be mixed, with some users experiencing installation issues while others report successful updates. According to Windows Latest, some users are encountering installation failures with error codes such as 0x8007371b, 0x800f0991, 0x80073712, and 0x80071a2d. There are also reports of the update getting stuck during installation or attempting to roll back changes after initial installation. One particularly concerning issue is that the update was supposed to fix Windows Firewall reporting errors in Event Viewer (Event 2042), but according to Windows Latest, the July update may actually be bringing this problem to more PCs that weren't previously affected. Microsoft has acknowledged this issue but hasn't provided detailed information about its cause, only mentioning it's related to an upcoming feature. Despite these problems, the update contains important security fixes that make it essential for most users, including patches for a zero-day vulnerability that's being actively exploited. The functional improvements to graphics, multimedia, and accessibility features are generally viewed positively, as they address specific user pain points. For users experiencing installation problems, alternative installation methods such as using the .msu offline installer from Microsoft Update Catalog or performing a place upgrade using the Media Creation Tool have been suggested as potential workarounds. However, these extra steps add complexity to what should be a routine update process.
