Microsoft has released the KB5060829 update for Windows 11, version 24H2, introducing a suite of enhancements aimed at improving user experience, accessibility, and system performance. This preview build, OS Build 26100.4484, is currently available to Insiders in the Release Preview Channel.
Taskbar Enhancements
The taskbar now features an intelligent icon resizing mechanism that automatically reduces the size of app icons when space becomes limited, ensuring all applications remain visible. Users can customize this behavior through three settings: always use small icons, never use small icons, or shrink icons only when the taskbar is full. Additionally, the visibility of indicators beneath open apps has been improved, and Quick Settings now provide descriptions for assistive tools like Narrator and Voice Access. Administrators can configure Start menu pins to apply only once at the first sign-in, allowing users to personalize their layout thereafter. (windowsreport.com)
Voice Access and Narrator Improvements
Voice Access now supports Simplified and Traditional Chinese and allows users to add custom words to the dictionary, enhancing dictation accuracy. The Narrator introduces a "Screen Curtain" feature that blacks out the display while reading aloud, offering privacy in public spaces. This feature can be toggled using the keyboard shortcut Caps Lock + Ctrl + C. (pureinfotech.com)
Windows Share and File Explorer Enhancements
The Windows Share window now displays link previews and offers new image compression levels—High, Medium, and Low—providing users with more control over shared content quality. File Explorer has improved performance when extracting large .7z and .rar archives, reducing wait times during file operations. (pureinfotech.com)
PC Migration Tool
A new PC migration tool is introduced within the Windows Backup app, facilitating the transfer of files and settings during the setup of a new computer. While the full functionality will be available in a future update, users can preview the landing and pairing experience in the app. (pureinfotech.com)
Default Browser Settings in the EEA
In the European Economic Area (EEA), changes have been made to default browser settings to comply with the Digital Markets Act. When setting a new default browser via Settings > Apps > Default apps, additional file and link types will be associated with the chosen browser if it registers them. The new default browser will be pinned to the Taskbar and Start menu unless the user opts out by unchecking the respective boxes. A separate one-click button is now available for browsers to change the default application for .pdf files, provided the browser registers for this file type. (pureinfotech.com)

- Storage Optimization: Fixed an issue that prevented unused language packs and Feature on Demand packages from being fully removed, leading to unnecessary storage use and longer Windows Update installation times.
- Windows Search: Enhanced reliability and resolved an issue that prevented users from typing in Windows Search in some cases. (pureinfotech.com)
