Microsoft has released its latest optional non-security preview update, KB5101684, which brings 42 bug fixes and feature improvements to Windows 11 users. This cumulative update is part of Microsoft’s monthly testing schedule, where they release updates before Patch Tuesday to gauge user feedback and identify any issues.
The KB5101684 update will install on Windows 11 24H2 and 25H2 systems, updating the operating system to build 26100.8973 for the former and 26200.8973 for the latter. The update includes fixes for a range of issues, including problems with File History backups, newly enrolled devices remaining in a noncompliant state, and files on DFS mapped drives being incorrectly marked as originating from the Internet.
One of the notable additions in this update is Voice Isolation support for Voice Access. This feature filters out background noise and other speakers to improve speech recognition, allowing users to choose between removing only non-speech background sounds or turning off filtering entirely. Another significant addition is the expansion of Windows Hello Enhanced Sign-in Security to supported external fingerprint readers, enabling desktop and other Windows 11 users to use compatible peripheral sensors for more secure authentication.
The update also includes several improvements to File Explorer, such as displaying file sizes in appropriate units (KB, MB, GB) instead of just KB-only. This makes it easier for users to understand file sizes at a glance. Additionally, middle-clicking to open a folder in a new tab is now supported in the Address Bar and Home page, providing a more consistent and efficient navigation experience across File Explorer.
Microsoft has also included several high-confidence device targeting data updates, increasing coverage of devices eligible to automatically receive new Secure Boot certificates. This will improve device security and reduce the risk of malware attacks. Furthermore, this update improves the stability of Office applications used in virtualized environments, ensuring a more reliable experience for users working with these apps.
The KB5101684 update is optional, and users can choose to install it by going to Settings > Windows Update > Check for Updates. Alternatively, they can manually download and install the update from the Microsoft Update Catalog. While this update does not include security updates, it still provides valuable improvements to the operating system’s stability and functionality.
In conclusion, the KB5101684 update offers a range of fixes and feature enhancements that will improve the overall user experience on Windows 11. By installing this optional update, users can take advantage of new features like Voice Isolation support for Voice Access and improved File Explorer navigation. As always, it’s essential to exercise caution when updating your operating system, but with Microsoft’s testing schedule in place, this update has been thoroughly vetted before its release.
