Written By published December 7, 2023

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 23601 to the Dev Channel.

What’s new in Build 23601

New features and improvements for Windows 365 Boot

The following improvements are beginning to roll out for Windows 365 Boot. (Local PC and Cloud PC should be on the same Dev Channel build.)

Dedicated mode for Windows 365 Boot: We are now launching a new mode for Windows 365 Boot – dedicated mode. You can now boot to your Windows 365 Cloud PC from your designated company-owned device. You will be able to seamlessly login to your Windows 365 Cloud PC from Windows 11 login screen using password-less authentication methods like Windows Hello for Business. The new dedicated mode also comes with fast account switcher experience to effortlessly switch profiles to login in, personalized experience with your username and password, display picture on lock and login screen, remember your username, etc. The feature will begin to get enabled for Windows 365 customers via a private preview in early 2024.

Customized company logo and name for Windows 365 Boot: In shared mode, organizations can now customize the login page to include their company branding from Intune. The feature will begin to get enabled for Windows 365 customers via a private preview in early 2024.

Fail fast mechanism for Windows 365 Boot: You no longer need to wait for the sign in process to the Cloud PC to complete only to find out Windows 365 Boot failed due to network issues or incomplete setup. The smart logic proactively informs users to resolve network issues or complete app setup so users can experience a smooth login to their Cloud PC.

Improved disconnect experience for Windows 365 Switch: You can now disconnect from their Cloud PC directly from their local PC. This can be done by going to Local PC > Task view > Right click on the Cloud PC button > Disconnect. We have also added tooltips on disconnect and sign-out options in the Cloud PC Start menu so that you can differentiate between these functionalities.

Improving discoverability of screen casting in Windows 11

Casting from your Windows PC allows you to wirelessly extend your display to another nearby PC, TV, or other external displays. After trying some improvements to this experience out with Windows Insiders in the Dev Channel with Build 23516, we’re making some additional refinement to those improvements that focus on educating users about the Cast feature and improving its discoverability in Windows 11. Those improvements include:

  • When doing multitasking activities on your PC such as often switching between windows to complete a task or using Snap Assist to organize your screen space, we will provide the suggestion to Cast via a notification toast.
  • We have updated the Cast flyout in Quick Settings with additional support for you in case you face any trouble discovering nearby displays, fixing connections, and more.

 

Cast flyout in Quick Settings now shows link for troubleshooting device discovery and other casting issues.

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Display and Graphics > Wireless Display and Casting.

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 this week, so the experience isn’t available to all Insiders just yet as we plan to monitor feedback before pushing it out to everyone.]

Changes and Improvements

[General]

  • Starting early next week, Windows Insiders in the Dev Channel on Build 23601 will be prompted to reboot to install Windows Configuration Update (KB1234567). Windows Configuration Updates are what we use to new features via Controlled Feature Rollout (CFR) technology. Windows Configuration Update (KB1234567) does not enable any new features as we’re testing the delivery of these updates via our servicing pipeline, and the reboot prompt to install them. After rebooting to install this update, it will be listed under “Other Updates” under Settings > Windows Update > Update History.

[Copilot in Windows*]

  • We are trying out the ability to “undock” Copilot in Windows with Windows Insiders. Just click the new icon to unpin the Copilot panel at the top right in the header. While undocked, Copilot can appear above or below other apps in Windows while maintaining its fixed position on the desktop. This allows users to access Copilot while minimizing disruption to other user activities. Additionally, can resize the Copilot window for a more comfortable experience. Simply click-and-drag the edge of the Copilot window to adjust the width to your needs.

  • We are trying out a change where when swiping from the right edge of the desktop on a touch display will open Copilot instead of notifications.

[Windows Share]

  • The Windows share window now supports sharing with WhatsApp under the “Share using” section. If you don’t have WhatsApp installed, you can choose to install it from Windows share window directly. Over time, we plan to try this experience out with other apps as well.

[Nearby Sharing]

  • We are introducing the ability to quickly give your device a more friendly name to identify sharing to and from with nearby share under Settings > System > Nearby sharing. This change originally began rolling out with Build 23545, but we are re-rolling it out with improvements to the experience. Let us know what you think.

[Narrator]

  • Narrator users can now use voice access to open applications, dictate text and interact with elements on the screen using their voice. Narrator users can use voice access to give Narrator commands using their voice . For e.g., “speak faster”, “read next line”, etc. To get started, search for “voice access” in Windows search and set it up.

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 Dev Channel

REMINDER: The Dev Channel has been rebooted. Windows Insiders who were in the Dev Channel on 25000 series builds have been moved to the new Canary Channel. Going forward, the Dev Channel will receive 23000 series builds. Insiders who were moved to the Canary Channel and want to move back to the Dev Channel can follow these instructions to do a clean installation of Windows 11 and then re-join the Dev Channel to receive 23000 series builds.

The Dev Channel receives builds that represent long lead work from our engineers with features and experiences that may never get released as we try out different concepts and get feedback. It is important to remember that the builds we release to the Dev Channel should not be seen as matched to any specific release of Windows and the features included may change over time, be removed, or replaced in Insider builds or may never be released beyond Windows Insiders to general customers. For more information, please read this blog post about how we plan to use the Dev Channel to incubate new ideas, work on long lead items, and control the states of individual features.

In some cases, features and experiences may go out to the Canary Channel first before going out to the Dev Channel however the Dev Channel will provide better platform stability. As we get closer to shipping, some features and experiences will also make their way to the Beta Channel when they are ready.

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.
