Insider Windows 11 Insider Canary 26080.1 and Dev 26080.1300 (KB5037139) or 26080.1400 (KB5037140) - March 18

UPDATE 3/20:



UPDATE 3/18: We are starting to roll out two servicing updates to Windows Insiders in the Dev Channel. Both these updates do not include anything new and are designed to test our servicing pipeline for Windows 11, version 24H2. Most Insiders in the Dev Channel will receive Cumulative Update Build 26080.1300 (KB5037139). However, Insiders that have Virtualization Based Security (VBS) turned on will receive Build 26080.1400 (KB5037140) and may not experience a restart upon installing the update. Arm64 devices, even with VBS turned on, will only receive Build 26080.1300 (KB5037139).

---

UPDATE 3/15: We are starting to roll out Cumulative Update Build 26080.1201 (KB5037135) to Windows Insiders in the Dev Channel. This update does not include anything new and is designed to test our servicing pipeline.

---

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 26080 to the Canary and Dev Channels. We are releasing ISOs for this build – they can be downloaded here.

Insiders in the Canary Channel will receive Build 26080.1 while Insiders in the Dev Channel will receive Build 26080.1100 (KB5037133) as we test delivery of a full build and a servicing update at the same time. There is no difference between the two of these as Build 26068.1100 does not include any additional code.

Two important notes:

• If you’re experiencing an issue with Settings crashing or not loading the Windows Update settings page to download and install Build 26080 – you may have to reboot to correct the issue.
• Insiders on Build 26080 and higher who have Dev Drives should no longer see their Dev Drives breaking when rolling back as long as you roll back to Build 26063 and higher. (Insiders in the Dev Channel will need to wait for another new build to get released to ensure rollback happens to build that has this issue fixed.)

The Canary and Dev Channels receiving the same builds is only temporary. During the times in which the Canary and Dev Channels are on the same builds (e.g. Build 26080), the window is open for Insiders in the Canary Channel to switch to the Dev Channel. At some point in the future, the Canary Channel will jump to higher build numbers and the window will be closed.

NOTE: Some features may begin rolling out to the Canary Channel first before the Dev Channel even if the two channels have the same build.

What’s new in Build 26080​

Updates to Microsoft Teams in Windows 11​

Starting with Windows 11, version 24H2, Teams users will get access to a preview experience of the new, unified Microsoft Teams experience on Windows. In this preview, Microsoft Teams will be available as a single application, enabling users to seamlessly switch between multiple cloud environments, tenants, and account types across personal and work. This new, unified application will soon be rolled out to commercial customers as well, through the normal update process. To add or access additional accounts, select your profile picture at the upper right corner of Teams when you sign into Teams.


Teams work user interface showing the Me control open with both work and personal account.

We received consistent feedback from personal and work users: you prefer a single Teams app that allows you to easily access and switch between personal and work accounts. This update lets you use one app for all kinds of Teams accounts.


Teams personal account user interface over Teams work user interface.

You can join any Teams meeting with ease. In upcoming builds, when you are joining a meeting, you can select the account you want to use. You will also be able to join a meeting without signing in.

Notifications have been improved, showing which Teams account they belong to. In addition, personal notifications have more details, giving clear and easy actions from the notification banner.


A Teams notification that someone is calling.

You can now launch personal and work accounts simultaneously with separate icons on the taskbar. We listened to users about their communication needs in various aspects of their lives and how they want to use Teams. The feedback was clear that a multi-window experience is preferred.

Other things to know:

• This unified preview app experience is labeled “Microsoft Teams (work or school)”. The app name will be automatically updated to “Microsoft Teams” in future releases.
• This is a preview release, and you will notice some changes from your current experience using Microsoft Teams (free) and Microsoft Teams (work or school). These changes and more updates will continue until we reach general availability. Notably in this release, Teams will launch into a separate icon for single accounts.
• We will remove the standalone consumer app, “Microsoft Teams (free)”, in future releases.
• If you lose access to either Teams applications through use of the Windows Insiders Program, you can access your preferred Teams application from this download page.
• For Enterprise Admins, the ability to sign in with Microsoft accounts will be part of a normal monthly update, there is no new app to install if you have new Teams. The functionality is targeted for preview in April and general availability in May. The ability for users to sign in with Microsoft accounts will follow all sign in restriction polices as it has for all versions of Teams. Admins can learn more in Message Center (MC719659).
• [ADDED] This preview version of Microsoft Teams is immediately available on clean installs of Windows 11 Insider Preview Build 26080 and higher.
• [ADDED] Existing Windows Insiders need to be on Microsoft Teams version 24057.2000.2723.3544 or higher to see this capability, which is rolling out gradually.

Introducing Power Automate via Copilot in Windows

Power Automate is a low-code automation solution that is part of the Power Platform. We’re excited to introduce the Power Automate plugin in Copilot in Windows. This first release of the plugin offers automation features for Excel, PDF manipulation and file management.

To use the plugin, download or update Power Automate Desktop to the latest version from the Microsoft Store. Currently plugins are only accessible if you are signed in to Copilot in Windows with a Microsoft account.

After you have Power Automate installed and you activate the plugin in the plugins section in Copilot in Windows, you can ask for tasks such as:

• Write an email to my team wishing everyone a happy weekend.
• List the top 5 highest mountains in the world in an Excel file.
• Rename all PDF files in a folder to add the word final at the end.
• Move all word documents to another folder.
• I need to split a PDF by the first page. Can you help?

Do you want to share your feedback on the Power Automate plugin or do you have other automation scenarios that you would like us to support? Feel free to contact us: powerautomate-ai@microsoft.com.

[The rollout continues for these Copilot in Windows improvements to Windows Insiders in the Canary and Dev Channels today, so the experience isn’t available to all Insiders just yet.]

FEEDBACK: Because of an issue with our feedback pipeline, please do not use the in-line feedback form that opens from thumbs up/down for these actions right now, and instead file feedback about using these in Feedback Hub (WIN + F) under Desktop Environment > Copilot in Windows.

Changes and Improvements​

[Copilot in Windows*]​

• We are beginning to roll-out an updated Copilot in Windows experience that adds the ability to switch between the existing “docked” behavior that attaches Copilot to the side of your desktop, and a new mode where it acts like a normal application window which you can resize and move around your screen. As part of this change, we’re also introducing some under-the-hood improvements as well. This experience is beginning to roll out to Windows Insiders in the Canary Channel As always, please report any issues you experience to us via Feedback Hub.

Fixes for known issues​

[General]​

• IMPORTANT NOTE FOR DEV DRIVE USERS: Insiders on Build 26068 and higher who have Dev Drives should no longer see their Dev Drives breaking when rolling back as long as you roll back to Build 26063 and higher. Rolling back to earlier builds may still result in issues with Dev Drives.
• IMPORTANT NOTE: Fixed an issue causing Windows Update in Settings to not load or crash in Build 26063. If you are still on Build 26063 and encounter this, rebooting may resolve the issue. If it doesn’t, the update should still eventually download on its own – appreciate your patience.
• Fixed an issue for Narrator not working when setting up a device or in Advanced Startup.

[Copilot in Windows*]​

• Fixed an issue where if you turned the Copilot icon off and back on in Settings never showed it on your taskbar again.

[Taskbar & System Tray]​

• Fixed a memory leak related to showing the tooltip for the date and time in the taskbar when you had enabled additional clocks.

[File Explorer]​

• Fixed an underlying issue believed to be the cause of some Insiders finding File Explorer had started freezing and using unexpectedly high CPU in the last couple builds. Please file feedback in the Feedback Hub if you continue experiencing this after upgrading.
• Fixed an issue where your preference for “Show extracted files when complete” when extracting files in File Explorer wasn’t persisting across upgrades.
• Fixed a timing issue where when you start a search from Home in File Explorer, it might unexpectedly show no results the first time you tried.
• Fixed an issue causing the Details view in File Explorer to be unexpectedly cramped in recent builds when using compact mode.
• Made a change to help address an issue where after a DWM crash, when you opened File Explorer it could just show a blank area on top instead of rendering the area correctly.
• Fixed an issue where the 7zip and ZIP compression options weren’t displaying correctly for Insiders with the English (United Kingdom) display language.

[Task Manager]​

• Fixed an issue which could lead to your GPU showing as -1 in Task Manager.
• Fixed an issue where Task Manager may unexpectedly show no GPU % used (when that was not the case).
• Fixed an issue impacting Task Manager reliability.

[Audio]​

• Fixed an issue causing HDMI connected devices to not have audio in the last few builds.

[Input]​

• Fixed an issue causing the input switcher (WIN + Space) design to revert to an older style and draw in the wrong location.
• Fixed an issue where DWM could hang when writing with pen in Snipping Tool.
• Fixed a high hitting ctfmon.exe crash, which could impact the ability to input text.
• Fixed an issue where magnifier wasn’t following the mouse cursor when centered on screen in recent builds.
• Fixed an issue where mouse cursor shadows (if enabled) were not rendered correctly with large cursors.
• Fixed an issue where the mouse cursor was unexpectedly leaving a trail of mice on the screen.
• Fixed an issue which could lead to some mice and keyboards not working in safe mode.
• Fixed an issue where when waking your PC from sleep in Build 26063 the touchpad might be banged out in Device Manager, resulting in the mouse cursor not showing when you tried to use it.

[Settings]​

• Fixed an issue where a Display Connection section was incorrectly showing up under Settings > System > Display > Graphics that when clicked, would crash Settings.
• Fixed an issue where a brightness slider might not show in Settings > System > Display in recent builds even though a brightness slider was available for you to use in Quick Settings.

[Other]​

• Fixed an underlying issue which could lead to Snipping Tool hanging.
• Fixed an underlying dxgi.dll issue which led to some app and game crashes in Build 26058+.
• Fixed an underlying issue with winmmbase.dll which could lead to app crashes in Build 26058+.
• Fixed an issue related to tcpip.sys which was causing some Insiders to see bugchecks with UNEXPECTED_KERNEL_MODE_TRAP in the last few builds.
• Fixed an issue which was causing some Insiders to see bugchecks with SYSTEM_SERVICE_EXCEPTION in the last few builds.
• Fixed an issue which was causing some Insiders to see bugchecks with DPC_WATCHDOG_VIOLATION in the last few builds.
• Fixed an issue where if you attempted to use the Windows Update troubleshooter, it would show error 0x803C010A.

Known issues​

[General]​

• [IMPORTANT NOTE FOR GAMERS – UPDATED!] Most popular games should work correctly again in the most recent Insider Preview builds in the Canary and Dev Channels. Please be sure to submit feedback in Feedback Hub on any issues you see with playing games on the latest builds.
• [UPDATED] We’ve made some more changes to help reduce the number of rollbacks (with error code 0xC1900101) when installing the latest builds and are continuing to investigate reports. If your PC rolls back trying to install this build, please file feedback in Feedback Hub.
• In some cases, the File Explorer context menu no longer has the acrylic effect. This will be fixed in a future flight.
• We’re investigating reports of mouse cursor issues after installing Build 26058+, including that the cursor is disappearing in some apps. If you’re experiencing issues, please file feedback describing exactly what you’re seeing under Input and Language > Mouse in the Feedback Hub. This build includes a number of fixes to help with recent reports.
• When opening the context menu in File Explorer, the icons may appear out of place and overlapping text.
• [NEW] Running the command “sudo pwsh” won’t work properly in this build.

[Copilot in Windows*]​

• [NEW] Voice access does not work reliably with the updated Copilot in Windows experience that introduces the ability for Copilot to act like a normal application window noted in the above blog post.
• [NEW] Using Windows Ink to write in Copilot will not work with the updated Copilot in Windows experience that introduces the ability for Copilot to act like a normal application window noted in the above blog post.
• [NEW] When Copilot in Windows is docked and resized to a large width, Copilot does not always fill the width of the panel. Resizing Copilot to less than half of the width of your screen usually fixes this issue.
• [ADDED 3/14] With the updated Copilot in Windows experience that introduces the ability for Copilot to act like a normal application window, you may not be able to bring focus to the “…” or refresh buttons within Copilot when using a keyboard (ex: by using tab to cycle through buttons).

For developers​

You can download the latest Windows Insider SDK at aka.ms/windowsinsidersdk.
SDK NuGet packages are now also flighting at NuGet Gallery | WindowsSDK which include:

• .NET TFM packages for use in .NET apps as described at aka.ms/windowsinsidersdk
• C++ packages for Win32 headers and libs per architecture
• BuildTools package when you just need tools like MakeAppx.exe, MakePri.exe, and SignTool.exe

These NuGet packages provide more granular access to the SDK and better integration in CI/CD pipelines.
SDK flights are now published for both the Canary and Dev Channels, so be sure to choose the right version for your Insider Channel.
Remember to use adaptive code when targeting new APIs to make sure your app runs on all customer machines, particularly when building against the Dev Channel SDK. Feature detection is recommended over OS version checks, as OS version checks are unreliable and will not work as expected in all cases.

Reminders for Windows Insiders​

• The Canary and Dev Channels receive builds with features and experiences that 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.
• Many features in the Canary and Dev Channel are rolled out using Control 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 these channels.
• As the Canary and Dev Channels receive the same builds, some features may begin rolling out to the Canary Channel first before the Dev Channel.
• While the Canary Channel is now on Windows 11, version 24H2, this is just temporary. At some point in the future, the Canary Channel will jump ahead to receiving new builds not matched to any specific release in a higher build series.
• To get off the Canary or Dev Channel, a clean install of Windows 11 will be required. As a reminder – Insiders can’t switch to a channel that is receiving builds with lower build numbers without doing a clean installation of Windows 11 due to technical setup requirements.
• The desktop watermark shown at the lower right corner of the desktop is normal for these pre-release builds.
• Check out Flight Hub for a complete look at what build is in which Insider channel.
• Copilot in Windows* in preview is being rolled out gradually to Windows Insiders in select global markets. The initial markets for the Copilot in Windows preview include North America, United Kingdom and parts of Asia and South America. It is our intention to add additional markets over time.

Thanks,
Amanda & Brandon
