Microsoft has released the KB5062553 update for Windows 11, version 24H2, bringing the OS build to 26100.4652. This cumulative update, dated July 8, 2025, introduces several enhancements and addresses various issues to improve system performance and security.
Key Improvements and Fixes:
- Taskbar and System Tray Enhancements: The taskbar now dynamically resizes icons to accommodate more applications when space is limited, ensuring all apps remain accessible. Users can adjust icon size preferences by navigating to Settings > Personalization > Taskbar > Taskbar behaviors. Additionally, the Accessibility menu in Quick Settings has been reorganized, providing text descriptions for assistive technologies like Narrator and Voice Access, facilitating easier identification and usage. (support.microsoft.com)
- File Explorer Performance: Performance improvements have been made when extracting archive files, particularly benefiting scenarios involving large numbers of files within extensive 7z or .rar archives. (support.microsoft.com)
- Graphics and Display: Underlying changes have been implemented to enhance display-related user experiences, including reducing screen flashing during certain display configuration transitions and eliminating unnecessary display resets that occurred in some cases. (support.microsoft.com)
- Input Method Editor (IME): An issue causing the Japanese touch keyboard to become unresponsive after switching between English and Japanese input has been resolved. (support.microsoft.com)
- Printing: A fix has been applied to address an issue where printed lines appeared unexpectedly thicker than intended. (support.microsoft.com)
- Remote Desktop: An issue causing Remote Desktop sessions to freeze shortly after connection, rendering mouse and keyboard input unresponsive, has been addressed. (support.microsoft.com)
- Windows Search: The update enhances the reliability of Windows Search, resolving issues where the search box responded very slowly, sometimes taking over 10 seconds to become usable. (support.microsoft.com)
- Windows Hello: For enhanced security, Windows Hello facial recognition now requires color cameras to detect a visible face during sign-in. (support.microsoft.com)
- Kerberos Authentication: Protections have been added for a vulnerability occurring when a certificate authority is part of the Windows root store but not the NTAuth store. This change, enabled by default, might cause Event ID: 45 events to be logged on the domain controller. (support.microsoft.com)
- Noto Fonts Display: There are reports of blurry or unclear CJK (Chinese, Japanese, Korean) text when displayed at 96 DPI (100% scaling) in Chromium-based browsers such as Microsoft Edge and Google Chrome. As a temporary workaround, users can set their display scaling to 125% or 150% to improve text clarity. (bleepingcomputer.com)
