Announcing Windows 11 Insider Preview Build 26016 (Canary Channel)

Written By published December 13, 2023

UPDATE 12/15: We are starting to roll out Cumulative Update Build 26016.1012 (KB5034402). This update does not include anything new and is designed to test our servicing pipeline for builds in the Canary Channel.

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 26016 to the Canary Channel. This will be our last Canary Channel flight until January 2024.

We are releasing ISOs for this build – they can be downloaded here.

NOTE: Some Insiders may experience a download “loop” where the build appears to download multiple times with an 8024200D error. The download will eventually succeed, and the build should install. 

REMINDER: As builds released to the Canary Channel are “hot off the presses,” we will offer limited documentation for builds flighted to the Canary Channel including documenting only the most significant and highly impactful known issues. Please note that we will not publish a blog post for every flight – only when new features are available in a build.

What’s new in Build 26016

Windows Protected Print Mode

Windows protected print mode lets your PC exclusively print using the Windows modern print stack which is designed to work with Mopria certified printers only. With Mopria certified printers, users no longer must depend on third-party software installers as well as get additional security benefits. Print devices will “just work” resulting in a safe and streamlined installation and printing process. Read more about the security benefits of switching to IPP printing here.

Here is how you can enable Windows protected print mode. These instructions are also published in a Quest for Insiders in Feedback Hub:

  1. Press Start.
  2. Open the Local Group Policy Editor.
  3. Navigate to Computer Configuration > Administrative Templates > Printers.
  4. Right click on ‘Configure Windows protected print’ and click ‘Edit’.
  5. Select the ‘Enabled’ radio button.
  6. Click ‘Apply’ and click ‘OK’.
  7. Windows protected print is now enabled.

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Devices and Drivers > Print.

Changes and Improvements

[Taskbar & System Tray]

  • Added an icon to the “Diagnose network problems” entry when right clicking the Wi-Fi icon in the taskbar.

[Settings]

  • [ADDED] We’re beginning to rollout a change that renames the Phone Link settings page under Settings > Bluetooth & devices to Mobile devices. As part of this change, a new section will appear for allowing a PC to access mobile devices – this section currently does not introduce anything new yet and we’ll have more to share in a future flight. 
The Phone Link settings page is being renamed to Mobile devices.

Fixes for known issues

  • Fixed an issue causing WinRE (Windows Recovery Environment) to not render correctly in the previous flight.
  • Fixed an issue causing keyboard shortcuts to not work on the desktop – including using the delete key to delete files off of your desktop, CTRL key combos to take action on desktop icons, or using ALT + F4 on the desktop to open the shutdown dialog.
  • Fixed an underlying issue causing the details pane in File Explorer to unexpectedly take keyboard focus sometimes.
  • Fixed an issue causing it to not be possible to save changes to shortcuts (.lnk) in the previous flight, as they would cite something was using the process.
  • We did some work to help improve the performance of loading Settings > Apps > Installed apps.
  • Fixed an issue where Settings was crashing when attempting to navigate to the “System and Reserved” section under System > Storage.

Known issues

[General]

  • [REMINDER] Some popular games may not work correctly on the most recent Insider Preview builds in the Canary Channel. Please be sure to submit feedback in Feedback Hub on any issues you see with playing games on these builds.
  • We’re investigating an issue where the print queue is showing a messaging saying it can’t find the app when opened.
  • [NEW] We’re investigating an issue causing a small number of Insiders to not be able to open Settings after the previous flight. If you are impacted, please see this forum post for a workaround.
  • [NEW] Navigating to Settings > Power will crash Settings on this build. As a workaround, you can use commands to configure power modes on your device. powercfg /overlaysetactive will set the active user configured power mode, powercfg /q OVERLAY_SCHEME_CURRENT will get the active user configured power mode. For more information on using powercfg to adjust these settings, click here.

[Widgets]

  • You may experience a loading delay when the Microsoft Start feed is reenabled.
  • Announcements from the Microsoft Start feed are still shown on the taskbar after the feed is hidden.
  • The Widgets Board should automatically close and reopen when enabling or disabling feeds.
  • Keyboard navigation from settings subpages back to the top-level Settings page is broken.
  • Incorrect spacing and fonts used in some settings pages.

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:

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.

About the Canary Channel

The Canary Channel is the place to preview platform changes that require longer-lead time before getting released to customers. Some examples of this include major changes to the Windows kernel, new APIs, etc. Builds that we release to the Canary Channel should not be seen as matched to any specific release of Windows and some of the changes we try out in the Canary Channel will never ship, and others could show up in future Windows releases when they’re ready.

The builds that will be flighted to the Canary Channel are “hot off the presses,” flighting very soon after they are built, which means very little validation and documentation will be done before they are offered to Insiders. These builds could include major issues that could result in not being able to use your PC correctly or even in some rare cases require you to reinstall Windows. We will offer limited documentation for the Canary Channel, but we will not publish a blog post for every flight – only when new features are available in a build.

Our Canary Channel won’t receive daily builds; however, we may ramp up releasing builds more frequently in the future.

The desktop watermark you see at the lower right corner of your desktop is normal for these pre-release builds.

*Availability of Copilot in Windows: 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.
