Microsoft released cumulative update KB5079481 (Build 28020.1743) for Windows 11 version 26H1, available to insiders on the Canary channel. This build belongs to the br_release development branch and is activated using the feature enablement package KB5073122. The Canary channel is intended for early preview of the latest changes: builds are released immediately after creation, with limited documentation and without thorough testing, so they may be unstable. Some tested changes will never be released, while others may appear in future versions of Windows.
- Joint audio listening (preview) — new control features. This feature allows two users to listen to audio simultaneously through compatible devices supporting Bluetooth LE Audio. This update adds separate volume sliders for each listener, allowing independent volume adjustment without affecting the other user. The overall volume can still be changed through quick settings, the device, or the keyboard. A new indicator also appears on the taskbar during joint listening: clicking it opens options to change volume or stop playback. The device ecosystem has expanded: Samsung Galaxy Buds 4 and Buds 4 Pro, Sony WF-1000XM6, and Xbox Wireless Headset are now supported.
- Context menu. When right-clicking .exe, .bat, or .cmd files, the Open item in the context menu now uses the same icon as the default application for that file type.
- File Explorer. Improved reliability of unlocking files downloaded from the internet so they can be viewed in File Explorer.
- Updated Feedback Hub. A modern interface and redesigned user experience are introduced. Simplified feedback submission: a single template with category search. Simplified navigation: My Feedback section in the navigation pane, and Community Feedback instead of All Feedback. The Announcements page has been removed — news is now in the Windows Insider Blog. A new feedback type Appreciation has been added to note what works well. The ability to choose public or private feedback is now available. A compact feedback submission mode is also available for quick on-the-fly submission with the option to switch to the full version.
Installation via Windows Update: go to Settings > Windows Update and click Check for updates. A computer restart is required to complete the installation.
To exit the Canary channel, a clean installation of Windows 11 is required, as insiders cannot switch to a channel with lower build numbers without it for technical reasons. The watermark in the lower-right corner of the desktop is normal for these preview builds.
