Microsoft has released the latest optional update for Windows 11, KB5101684, which brings 42 bug fixes and feature improvements to the operating system. This non-security preview update is part of Microsoft’s regular schedule to test new fixes and features before they’re included in Patch Tuesday updates.
The KB5101684 update affects both Windows 11 24H2 and 25H2 systems, bringing build numbers up to 26100.8973 and 26200.8973 respectively. The update includes a range of fixes for common issues, such as file backup problems with File History, newly enrolled devices remaining in an incorrect noncompliant state, and files on DFS mapped drives being mistakenly marked as originating from the internet.
One of the most significant features included in this update is Voice Isolation support for Voice Access. This new feature filters out background noise and other speakers to improve speech recognition, allowing users to choose whether to remove only non-speech background sounds or turn off filtering entirely. Additionally, Windows Hello Enhanced Sign-in Security is expanding to supported external fingerprint readers, enabling desktop and other Windows 11 users to use compatible peripheral sensors for more secure authentication.
Microsoft is also gradually rolling out several new features after installing the update, including improved File Explorer navigation, enhanced search results for misspelled or partial app names, and new precision touchpad controls for scrolling and zooming. The company has stated that these features will be available to all Windows 11 users in due course.
The KB5101684 update is available through the Settings app under Windows Update, where you can click “Check for Updates” to install it manually. Alternatively, you can download and install the preview update from the Microsoft Update Catalog if you prefer a more manual approach. However, please note that this update is optional, so you’ll need to explicitly choose to install it unless you have the “Get the latest updates as soon as they’re available” option enabled.
For Windows 11 users, this update offers significant improvements and bug fixes that can help resolve common issues and enhance overall performance. While some features are still being rolled out gradually, it’s essential for users to keep their operating system up-to-date to ensure they have access to the latest security patches and feature enhancements. As with any software update, we recommend carefully reviewing the release notes and change log before installing KB5101684 to understand exactly what changes and fixes are included.
