Microsoft has rolled out Windows 11 Insider Preview Build 26220.7051 (KB5067115) to users in the Dev and Beta Channels, marking another step forward for version 25H2. The update continues Microsoft’s approach of gradually introducing new features and system enhancements through controlled rollouts, with the goal of improving productivity, accessibility, and gaming performance across devices.
For this build, the Dev and Beta Channels are now receiving the same updates, giving Windows Insiders the opportunity to switch between the two as long as both share the same base version. Once the Dev Channel advances to a higher build number, that window will close, so testers are being encouraged to decide which channel best fits their needs before that happens.
Copilot Gets a Taskbar Upgrade
The standout feature in this build is the addition of Ask Copilot, which integrates Microsoft’s AI assistant directly into the Windows taskbar. Designed for quick access, this tool brings Copilot Vision and Voice into the user’s workflow with a single click. Users can interact through text, voice, or guided assistance, allowing for more natural engagement while still maintaining privacy controls.
Ask Copilot functions alongside the existing Windows Search, using the same APIs to deliver results for apps, files, and settings. The feature doesn’t access personal data, ensuring that privacy remains consistent with standard Windows operations. It can be enabled through the system settings menu under Personalization > Taskbar > Ask Copilot, and users can choose whether Copilot starts automatically at login.
Full Screen Experience Expands to More Handhelds
Following its debut on the ASUS ROG Xbox Ally and ROG Ally X, the full screen experience (FSE) is now rolling out to additional handheld gaming devices running Windows 11. The mode is built to make portable PCs feel more like consoles, emphasizing clean navigation and optimized performance.
Paired with the Xbox PC app, the feature simplifies access to games while minimizing background processes that could interrupt gameplay. Players can activate the mode through Settings > Gaming > Full screen experience and designate Xbox as the home app. The update is currently available for ASUS and MSI handhelds, with support for more devices expected soon.

Bluetooth Shared Audio Enters Preview
Microsoft is introducing shared audio (preview), a new feature powered by Bluetooth LE Audio broadcast technology, aimed primarily at Copilot+ PCs. The functionality allows two users to connect supported audio devices to a single PC at once, making it easier to share sound while watching videos, listening to music, or studying together.
The setup process is straightforward: users can open Quick Settings, select the “Shared audio (preview)” tile, choose two compatible devices, and begin sharing. Compatibility details and further guidance are available on Microsoft’s support channels.
Performance and Compatibility Improvements
The build also delivers updates to Prism, Microsoft’s emulator for Windows on Arm devices. The enhanced version supports a wider range of 64-bit x86 applications by improving CPU feature emulation, helping expand app compatibility and improve performance stability.
Several system-level fixes are included as well. These address issues with USB connectivity, Start menu responsiveness, File Explorer speed, and visual consistency. Microsoft has also corrected memory leaks tied to slideshow lock screens, refined login performance for new accounts, and improved Settings and accessibility features. Network performance issues affecting Ethernet upload speeds have been resolved in this release.
General: Resolved issues affecting USB devices and keyboards after recent updates.
Start Menu: Fixed a problem where folders could become invisible after interaction.
File Explorer: Enhanced responsiveness in network locations and reduced launch time. Fixed icon and tooltip inconsistencies.
Lock and Login: Addressed memory leaks in slideshow lock screens and improved login performance for new accounts.
Settings: Fixed UI overlap in the Settings search box.
Accessibility: Improved compatibility with screen readers and resolved text rendering issues in certain apps.
Network: Corrected an issue that could reduce Ethernet upload speeds.
Ongoing Issues and Rollout Notes
Microsoft has acknowledged a few ongoing issues in this build, including occasional Start menu failures when clicked, missing icons in the system tray, and visual inconsistencies in the File Explorer copy dialog while using dark mode.
The company continues to use Controlled Feature Rollout (CFR) to release new features gradually. This allows early testers to receive updates first through an optional toggle in Settings > Windows Update, while other users receive them later once feedback has been analyzed.
As always, Microsoft reminds Insiders that experimental features may change or be removed before general release. Localization and stability updates will continue throughout the 25H2 cycle.
Taskbar and System Tray: Start menu may not open on click for some users but will open with the Windows key. Some apps may not appear in the system tray.
File Explorer: Copy dialog may display visual glitches in dark mode, including missing scrollbar and footer.
