Insider KB5067115 Windows 11 Insider Dev and Beta build 26220.7051 (25H2) - Oct. 31

UPDATE 11/07:



Update: 11/5 – We are rolling out Quality Update 26220.7052. This update does not include anything new, doesn’t require a reboot, and is designed to test our servicing pipeline.

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 26220.7051 (KB5067115) to the Dev & Beta Channels.

Starting today, we are beginning to offer the same Dev Channel updates based on Windows 11, version 25H2 to Windows Insiders in the Beta Channel as a recommended update.

If you are an Insider in the Dev Channel, you now have a window to switch from the Dev Channel to the Beta Channel if you would like. This window will only be open for as long as we’re releasing the same 25H2-based updates across both the Dev and Beta Channels. After we move Dev Channel forward to a higher build number, the opportunity to switch between these channels will close. When the Dev Channel jumps ahead, things might not be as stable as the Dev Channel is today, so we highly encourage you to evaluate which channel you would like to be in during the time in which the window to switch is open.


For more information, see the Reminders section at the bottom of this blog post.


UPDATE 11/04:
We have an out‑of‑band feature rolling out gradually to #WindowsInsiders in the Dev & Beta Channels! You can choose your default Widgets dashboard in the new full‑page settings and see numbered badges showing alert counts. More details will be in the next Dev/Beta flight blog.

New features gradually being rolled out with toggle on*​

Introducing Ask Copilot in taskbar​

The Ask Copilot experience in the Windows taskbar demonstrating a query for ‘Out’ that shows apps, files, settings, and Copilot chat suggestions.

With the new Ask Copilot in 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 log in” toggle in the Copilot app settings.


Ask Copilot in 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.

Fixes gradually being rolled out with toggle on*​

[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 Start menu could result in the folder becoming invisible.

[File Explorer]​

• Made some underlying changes to help 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 issues where tooltips were not showing up as expected when using 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 which could cause logging into be very slow the first time when logging into a new account.

[Settings]​

Known issues​

[Taskbar & System Tray]​

• We’re investigating an issue which 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 dark mode version of the copy dialog.
• Scrollbar and footer are missing and showing a white block instead when text is scaled in dark mode version of the copy dialog.

Reminders for Windows Insiders in the Dev & Beta Channels​

• Updates are based on Windows 11, version 25H2 via an enablement package (Build 26220.xxxx).
• Many features are rolled out using Controlled Feature Rollout technology, starting with a subset of Insiders and ramping up over time as we monitor feedback to see how they land before pushing them out to everyone in this channel.
• For Windows Insiders who want to be the first to get features gradually rolled out to you, you can turn ON the toggle to get the latest updates as they are available via Settings > Windows Update*. Over time, we will increase the rollouts of features to everyone with the toggle turned on. Should you keep this toggle off, new features will gradually be rolled out to your PC over time once they are ready.
• Features and experiences included in these builds may never get released as we try out different concepts and get feedback. Features may change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they’re ready.
• Some features in active development we preview with Windows Insiders may not be fully localized and localization will happen over time as features are finalized. As you see issues with localization in your language, please report those issues to us via Feedback Hub.
• Check out Flight Hub for a complete look at what build is in which Insider channel.

Thanks,
Amanda
