Hello Windows Insiders,
Today we are releasing Windows 11 Insider Preview Build 25982 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 25982
Copilot in Windows* in Preview
We are beginning to roll out Copilot in Windows in preview to Windows Insiders in the Canary Channel. Rolling this out in the Canary Channel to Insiders in the select global markets mentioned below will be gradual, so some Insiders will not see it immediately.
As Yusuf mentioned in his blog post last month, you can use Copilot to get help with summarizing a web page, composing an email, changing your settings to dark mode, or generating an image for that unique idea in your head. Need to enable Bluetooth or connect a new pair of headphones? Copilot can help. Not sure of the best way to capture a screenshot? Ask Copilot to do it for you. Copilot in Windows can change the way you use your PC and inspire you to try new things that you may not have thought of before. It is where productivity and creativity meet.
To get started, look for the Copilot icon on the taskbar or simply press WIN + C to launch Copilot in Windows using the same Microsoft account (MSA) or Microsoft Entra ID (formerly Azure Active Directory) account that you use to sign in on Windows.
Just click the “…” icon at the top right of the side bar in Windows Copilot to submit feedback on any issues you run into.
[We are beginning to roll this out, so the experience isn’t available to all Insiders in the Canary Channel just yet as we plan to monitor feedback and see how it lands before pushing it out to everyone.]
Availability*: 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.
SMB client encryption
Starting with this build (Build 25982), SMB now supports requiring encryption of all outbound SMB client connections. With this new option, administrators can mandate that all destination servers use SMB 3 and encryption, and if missing those capabilities, the client won’t connect. This enforces the highest level of network security as well as bringing management parity to SMB signing, which allows both client and server requirements.
For more information on configuring this SMB client encryption, review https://aka.ms/SmbClientEncrypt. For more information on SMB encryption, review https://aka.ms/SmbEncrypt.

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.
