Friday Windows 11 preview build is here, and it is a slightly different one. Build 26220.7051 (KB5067115) is out for both Dev and Beta Channels, where Microsoft now ships the same 25H2 build. This is also an opportunity for Dev Insiders to switch to the Beta Channel without reinstalling the operating system. After a brief period of time, Dev builds will move to higher numbers, and they may become less stable.
As for the new features in build 26220.7051, it introduces the Ask Copilot feature on the taskbar (one that Microsoft announced recently), the full-screen gaming experience for more handheld consoles, shared Bluetooth audio so that you can play audio on multiple headphones, File Explorer performance improvements, various fixes, and more.

Here is the changelog:
Introducing Ask Copilot in taskbar
With the new Ask Copilot in the taskbar, Copilot becomes a natural part of how you use your PC, ready to help, guide and collaborate the moment you need it.
This opt-in experience gives you one-click access to Copilot Vision and Voice, enabling more natural interaction in your flow. Whether through text, voice, or guided support with Copilot Vision, you can engage on your terms, in the way that works best for you. You’re always in control. As you type, results appear and update instantly, making it easier than ever to find what you need.

To get started, go to Settings > Personalization > Taskbar > Ask Copilot to enable the experience. You can also manage whether the Copilot app launches automatically at sign-in using the “Auto start on login” toggle in the Copilot app settings.
Ask Copilot in the taskbar complements the familiar Windows Search experience, so you can continue using Search as you always have from Start while trying out this new experience.
Ask Copilot uses existing Windows APIs to return apps, files, and settings—just like Windows Search—and does not grant Copilot access to your personal content. For more details, you can learn about privacy and control options for Microsoft Copilot here.

Full-screen experience
Following the initial launch of the full-screen experience (FSE) on the ASUS ROG Xbox Ally and ROG Xbox Ally X, today’s preview to Windows Insiders expands availability to additional Windows 11 handheld devices currently in market.
Designed with console-style navigation in mind, the Xbox PC app, paired with the full-screen experience, delivers a clean, distraction-free interface for handheld gaming. You’ll get smooth task switching and optimized performance, with background processes minimized and non-essential tasks deferred—so gameplay stays responsive and uninterrupted.
How to enable FSE:
On supported devices, go to Settings > Gaming > Full screen experience, then select Xbox as your home app. Once enabled, you can access FSE from Task View and Game Bar or configure your handheld for the full-screen experience on startup.
Availability:
- Currently available on ASUS ROG Xbox Ally and ROG Xbox Ally X
- Preview rolling out to MSI Claw models today
- Additional OEMs enabling their handhelds in the coming months

Shared audio (preview)
In this update, we are beginning the rollout of shared audio (preview), a new experience built on Bluetooth® LE Audio broadcast technology, for Copilot+ PCs. Shared audio allows two family members to watch movies together while traveling, or two students to share music while studying.
To get started, access the “Shared audio (preview)” tile in quick settings, select two supported paired and connected accessories and click “Share” to begin.

For more information about shared audio (preview), including details about compatible PCs and accessories, visit Extending Bluetooth® LE Audio on Windows 11 with shared audio (preview).
Here are the changes, improvements, and fixes that are rolling out gradually:
[Prism]
We are enabling the feature update to Prism, our emulator for Windows on Arm, that makes it possible for more 64-bit x86 (x64) applications to run under emulation by adding support for more CPU features under emulation. This support will be made available to any 64-bit x86 (x64) application under emulation by default, and 32-bit x86 applications can be opted in to the support using the emulation settings in the Properties window.
Please submit any feedback on compatibility issues or performance regressions through the Feedback Hub (Win + F) under Apps and the specific app you’re seeing issues with (if you don’t see the app listed, use “All other apps”) to help us ensure that this updated Prism provides a great experience.
[General]
- Fixed an underlying issue leading to keyboards or other USB devices not working for a small number of Insiders after the latest flights.
[Start menu]
- Fixed an issue where interacting with a folder or its contents in the Start menu could result in the folder becoming invisible.
[File Explorer]
- Made some underlying changes to help the responsiveness of File Explorer when navigating in network locations.
- Made some more underlying improvements to help reduce the launch time of File Explorer.
- Fixed an issue where “Open” in File Explorer’s context menu wasn’t showing the right icon for .exe, .cmd & .bat files (was showing a generic executable icon, instead of the default app for that file type).
- Fixed an issue where you might see your desktop icons move when interacting with files, such as opening or renaming them.
- Fixed a couple of issues where tooltips were not showing up as expected when navigating Home with a keyboard.
[Lock and login screens]
- Fixed a memory leak when your lock screen was set to slide show, which could lead to performance or reliability issues over time when unlocking your PC.
- Fixed an issue that could cause logging in to be very slow the first time when logging into a new account.
[Settings]
- Fixed an issue where the search box in Settings could become overlapped with the minimize and maximize buttons in the title bar.
[Other]
- Fixed an issue where, after the latest updates, screen readers might unexpectedly say “legacy window” without reading out the window contents when interacting with certain apps.
- Fixed an issue where, after the latest updates, text might not render correctly when editing content within a multiline text box in certain apps.
- Fixed an issue where protected content playback might fail on some machines after the latest updates.
- Fixed an issue that could cause Ethernet upload speeds to be significantly lower on some PCs after the latest updates.
And here is the list of known bugs:
[Taskbar & System Tray]
- We’re investigating an issue that is causing the Start menu to not open for some Insiders on click, although it will open if you press the Windows key. It’s believed this issue may also potentially impact the notification center (which you can open with WIN + N).
- We’re investigating an issue where, for some Insiders, apps aren’t showing in the system tray when they should be.
[File Explorer]
- Copy progress might flash when clicking more or less details in the dark mode version of the copy dialog.
- Scrollbar and footer are missing and showing a white block instead when text is scaled in the dark mode version of the copy dialog.
