Windows 11 Insider Preview Build 26220 Released in Dev Channel

11 Oct 2025

Microsoft has released Windows 11 Insider Preview Build 26220.6780 to the Dev Channel, introducing new features and fixes for testers. The update aims to enhance functionality for early adopters through improvements in search, personalization, and user interface design.

New Features and Enhancements

Several features are gradually rolling out to users who enable them via a toggle. Agent in Settings offers a new experience for modifying and recommending settings, while Drag Tray supports multi-file sharing and surfaces more relevant apps like WhatsApp and Snapchat. An improved Click to Do preview adds visual cues for quick actions, and a new OneDrive icon can be found in Accounts and Homepages. Additionally, there are Dark Mode enhancements for the Run dialog.

Stability and Fixes

Some key fixes include resolving crashes in File Explorer and the Taskbar, as well as correcting search result anomalies. Issues like unexpected Start menu behavior and taskbar conflicts have been addressed, ensuring a smoother user experience.

Known Issues and Precautions

Users should note disabled taskbar preview animations and issues in File Explorer's dark mode. An identified bug causes hardware conflicts with Xbox controllers, which can be temporarily resolved by uninstalling driver "oemXXX.inf" via Device Manager.

Insiders who enable the toggle in Settings > Windows Update gain early access to these features. It's crucial to be aware that Dev Channel features may change or not roll out in final versions. Microsoft continues localization and accessibility improvements across its releases.
