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.
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.
FEEDBACK: Please file feedback in Feedback Hub (Win + F) under Power & Battery > Energy saver.
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.
