Announcing Windows 11 Insider Preview Build 26002 (Canary Channel)

Written By published November 29, 2023

UPDATE 12/5: We are starting to roll out Cumulative Update Build 26002.1010 (KB5033735). 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 26002 to the Canary Channel.

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.

[ADDED 12/4] New widgets board settings

We’ve updated the widget settings experience, providing more ways for users to customize their widgets board experience.  One of the new settings enables you to just show widgets on your widgets board and another makes it easier for you to discover how to personalize your feed content.

The new settings experience also allows you to select the account you want to use for your Microsoft Start powered widgets and feeds. This means you are no longer limited to using the account you used to sign into Windows to drive those experiences, just like your other app powered widgets. You can easily manage the account used by Microsoft Start by navigating to ‘Microsoft Start’ settings under the ‘Personalize your content’ section in your widgets board settings. This change allows you to further personalize the experience to your preferences. The new settings experience is not limited by region.

[We are beginning to roll this out to Windows Insiders in the Canary, Dev, and Beta Channels today, so the experience isn’t available to all Insiders just yet as we plan to monitor feedback before pushing it out to everyone.]

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Desktop Environment > Widgets.

What’s new in Build 26002

Energy Saver

Starting with this build (Build 26002), we are introducing energy saver, which extends and enhances battery saver. It is an easy way to extend battery life and reduce energy use by trading off some system performance. It can be toggled on and off via Quick Settings in the system tray or configured to run automatically whenever the device reaches a certain battery percentage. While optimized to extend battery life, energy saver will be available when PCs are plugged in (this includes desktop PCs) for those aiming to conserve energy all the time.

Changes and Improvements

[Taskbar & System Tray]

  • We’re trying out a change that improves the overall performance and responsiveness of Quick Settings in the system tray.
  • We’re making it easier to manage VPN in Quick Settings. If you have a single VPN, a new split toggle lets you turn it on and off with a single click. If you have multiple VPNs, we’ve made some changes to the list to reduce the time it takes to start a connection.
  • We are beginning to roll out a new refresh button on the Wi-Fi Quick Settings flyout so you can now refresh the list of wireless networks available. There is also indication of scan progress to help you find nearby networks if the first scan does not reveal the one you are looking for.

  • This update starts the roll out of account-related notifications for Microsoft accounts on the Settings homepage. A Microsoft account connects Windows to your Microsoft apps. The account backs up all your data and helps you manage your subscriptions. You can also add extra security steps to keep you from being locked out of your account. This feature displays notifications across the Start menu and Settings. You can manage Settings notifications in Settings > Privacy & security > General.


  • Removed colored backplates from app icons in Settings > Apps > Installed apps, as well as Settings > System > Notifications. This is an early implementation with more fixes on the way in future flights.

Fixes for known issues

  • Fixed an issue which was causing installation of some apps, including Phone Link, to fail with error 0x87AF0813 in the previous flight.
  • Fixed an underlying issue in recent Canary Channel builds where the Microsoft Store was getting stuck when trying to check for and install app updates.
  • Fixed an issue causing Settings to crash when navigating to Bluetooth & Devices > Touchpad.
  • Fixed an issue which was causing File Explorer to crash on launch for people using a non-default regional sorting option.

Known issues


  • [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.
  • [NEW] After Build 26002 is done downloading and is ready to restart to finish the installation, the restart button is missing from the Windows Update Settings page. You can reboot by clicking the Windows Update icon in the system tray or open Start and reboot from the power button there. After installing Build 26002, Windows Update settings page may not load correctly, but if you close Settings and re-open (or reboot) and navigate to the Windows Update settings page it should load again.
  • We’re working on a fix for an issue where attempting to reboot into safe mode hangs on the boot logo.

[Widgets – Added 12/4]

  • [NEW] The Microsoft 365, Outlook Calendar, and To Do widgets get stuck in an error state when the Microsoft Start feed is disabled.
  • [NEW] You may experience a loading delay when the Microsoft Start feed is reenabled.
  • [NEW] Announcements from the Microsoft Start feed are still shown on the taskbar after the feed is hidden.
  • [NEW] The Widgets Board should automatically close and reopen when enabling or disabling feeds.
  • [NEW] Keyboard navigation from settings subpages back to the top-level Settings page is broken.
  • [NEW] Incorrect spacing and fonts used in some settings pages.

For developers

You can download the latest Windows Insider SDK at

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.
