Hello Windows Insiders,
Today we are releasing Windows 11 Insider Preview Build 26052 to the Canary and Dev Channels.
Insiders in the Canary Channel will receive Build 26052.1000 while Insiders in the Dev Channel will receive Build 26052.1100 (KB5035384) 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 26052.1100 does not include any additional code. (Arm64 devices in the Dev Channel will not receive Build 26052.1100.)
Flighting updates for Windows Insiders in the Canary & Dev Channels
Starting today, Windows Insiders in the Dev Channel are being moved from receiving 23000 series builds to receiving 26000 series builds.
Insiders in the Dev Channel will gain a set of new features such as energy saver, scrollable quick settings, QR codes for Wi-Fi sharing, support for creating 7-zip and TAR archives in addition to ZIP in File Explorer, Windows protected print mode, voice clarity, along with recent Server Message Block (SMB) protocol changes and improvements to Windows Local Administrator Password Solution (LAPS), and improvements across Settings and improvements for Bluetooth and Graphics as well. Note that apps such as Tips and WordPad will be removed after upgrading to this build.
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 26052), 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.
If you are a gamer, please take note that some popular games may not work correctly or crash when launched on these builds. Over time, we expect this experience to improve as bugs get fixed.
NOTE: As part of this move, rollouts for some features in the Dev Channel may get reset which means in a small number of cases features might disappear. As we ramp up feature rollouts, these features should return over time. 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 26052
Sudo for Windows
Sudo for Windows provides a new, yet familiar way to way to elevate processes directly from the command-line.
The sudo command can be configured to run in three different modes:
It is recommended that you review the security considerations for each mode here before enabling the sudo command on your machine.
Here is how you can enable the sudo command: Just navigate to Settings > System > For developers and toggle on the sudo command. Configure how the sudo command behaves by selected one of the modes in the drop-down menu (In a new window, with input disabled, inline).
NOTE: The setting for enabling Sudo may incorrectly be showing on Windows Server Insider Preview builds – this feature will not be available on Windows Server and the setting will be disabled in a future Server Insider Preview build.

Enhancements in Hearing Aid Support
As announced in October 2023, Windows took a step forward in accessibility, allowing direct pairing, audio streaming, and smooth call handling for customers with Bluetooth® Low Energy Audio (LE Audio) supported hearing aids on LE Audio-compatible PCs. Now, we are thrilled to introduce a set of features that will take this support to the next level: We’re introducing new capabilities to control audio presets, ambient sounds, and experience enhancements to the Settings > Bluetooth & devices page.
Customers can now adjust the audio presets that they or their audiologist configured in their hearing aids, right from the Settings or Quick Settings UI in Windows. These controls allow customers to quickly adjust the behavior of their hearing aids to their preference for the environment they’re in. Preset options and availability will vary based on the model and configuration of hearing aids.We’re also introducing capabilities for customers to adjust the volume of ambient sound captured by their hearing aids. These controls adjust the balance between streamed audio and sound picked up from the surrounding environment, helping customers choose what they want to focus on. Ambient sound control availability will vary based on the model of hearing aids.
These features require both your Windows device and hearing aid to support Bluetooth LE Audio. Note that not all Windows 11 PCs or hearing aids, even ones that support Bluetooth LE, have support for LE Audio. To learn more about LE Audio compatibility on Windows, please visit this link: Check if your Windows 11 PC supports Bluetooth Low Energy Audio. To learn more about LE Audio compatibility with hearing aids, consult your manufacturer or audiologist.
We’ve also enhanced the Bluetooth & devices settings page to provide additional functionality. Customers will now be able to:
These new enhancements are available for hearing aids and all other devices on this page. To try out this feature, go to Settings > Bluetooth & devices > Devices.
FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Devices and Drivers > Bluetooth – Audio quality, glitches, choppiness, and stuttering.
Audio mic test utility to test audio in different processing modes
Windows now offers a convenient way to test the difference between Default and Communication mode audio. This new utility can be found under the microphone properties via Settings > System > Sound. You can select the mode and record/listen to audio in both modes, allowing you to easily compare audio processing modes for applications built for the Windows ecosystem. Some audio drivers come with special audio effects for communications, and the toggle lets users hear how audio captured in your microphone sounds when recorded by a communications application versus a non-communications application. It’s important to note that the utility is for testing purposes only and will not affect the actual mode of the audio. You can use this to try out the Voice Clarity feature in the last flight!

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.
