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


UPDATE 3/20:


 Windows Blogs:

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.

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.

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.

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.

Improvements to Copilot in Windows* now rolling out to more Windows Insiders

We have been trying out a new runtime for Copilot in Windows* that allows you to manage more settings via Copilot, including accessibility-focused settings, and use Power Automate Desktop through Copilot! We are now rolling out these Copilot in Windows improvements to more Windows Insiders in the Canary Channel (which first began rolling out on 2/20) and beginning to roll these improvements out to Windows Insiders in the Dev Channel.

More built-in capabilities via Copilot in Windows


Try asking Copilot to turn on Narrator or Live Captions, turn on battery saver, show you available networks, even empty your recycle bin or clean up your storage. Here’s the full list of things you can ask Copilot to do!

New with this update:
  • Ask for available wireless networks.
  • Ask for system or device information.
  • Ask for battery information.
  • Ask to clean storage.
  • Ask to empty recycle bin.
  • Ask to toggle battery saver.
  • Ask to show startup apps.
  • Ask for your IP address.
  • Ask for system, device, or storage information.
Try accessibility features:
  • Ask to turn on narrator.
  • Ask to open voice access.
  • Ask to turn on magnifier.
  • Ask to change text size.
  • Ask to start live captions.
  • Ask to turn on high-contrast.
  • Ask to start voice typing.
Already live, now on the new runtime:

  • Ask to toggle Bluetooth.
  • Ask to toggle do not disturb.
  • Ask to add a device.
  • Ask to take a screenshot.
  • Ask to cast your screen to another monitor.
  • Ask to change your background image.

  • Ask to launch an application.
  • State that certain parts of your PC aren’t working: Audio, Windows Update, Camera, Bluetooth, Printer, Network, others.
  • Ask to snap a window.
  • Ask to start a focus session.
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: [email protected].

[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.

[Taskbar & System Tray]

  • You can turn on live captions more quickly by using the new quick setting. Just open quick settings from the system tray, scroll down, then select the live captions quick setting.


    The new live captions quick setting highlighted with a red box in the quick settings flyout from the system on the taskbar.

  • Updated the design of the progress bar under app icons to help make it easier to see. This will appear on the taskbar as well as the Start menu.

    Design of progress bar under app icons has been updated to show a thin line under the colored progress bar to make it easier to see.

  • When extracting files, if there is a file name conflict you can now choose to apply your selected action (skip, replace) for all conflicts.

[Windows Update]

  • Removed the What’s New link in Windows Update history for Windows Insiders – it will only show now for retail (released) versions of Windows. To check what’s new in Insider builds, please follow this blog.

[Printing]

  • [ADDED] Building off the printer improvements first introduced with Build 26020, we have added the ability to rename your printer directly from Settings > Bluetooth & devices > Printers & scanner.

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.

Join the club, I had that too (now seen on three different machines). fg2001gf11F thinks that it was something in the 26080.1201 update that broke it for later updates.....


...I too had to restore each of my machines to an earlier build before I could get the1400/1300 update to install.
My last restore point date was 1/28/2024 26040 was installed on 1/27/2024 I to was going to restore to earlier time but the date's make me believe that it would not help

I never rely on restore points these days, I've had issues in the past with some that failed to restore. I keep system images that I can go back to, if needed.

I agree. Never had success with restore point restoration, even way back to win 7, 8 - use backups from macrium.
