Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 23615 to the Dev Channel. We are releasing ISOs for this build – they can be downloaded here.
What’s new in Build 23615
USB 80Gbps
We are excited to announce support for the latest generation USB standard, USB 80Gbps, in this build of Windows. USB 80Gbps support will initially launch on select devices based on the Intel Core 14th Gen HX-series mobile processors, such as the new Razer Blade 18.
This is the first major version update of the USB4®standard and increases performance to 80Gbps from 40Gbps. It enables the next generation of high-performance displays, storage, and connectivity. It is fully backwards compatible with peripherals built for older generations of USB and Thunderbolt™ and works alongside all other USB Type-C features.
FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Devices and Drivers > Buses.
Changes and Improvements
[Copilot in Windows*]
- We are trying out opening Copilot automatically when Windows starts on widescreen devices with some Windows Insiders in the Dev Channel. This can be managed via Settings > Personalization > Copilot. Note that this is rolling out so not all Insiders in the Dev Channel will see this right away.
[Windows Share]
- For Microsoft Edge and other browsers that invoke the Windows share window, the Windows share window now supports the ability to share URLs directly to WhatsApp, Gmail, X (formerly Twitter), Facebook, and LinkedIn. In Microsoft Edge, you can invoke the Windows share window by clicking the share icon at the top right in the toolbar and choosing the Windows share options.
Fixes
[Task Manager]
- Fixed an issue which was impacting Task Manager reliability for some Insiders.
[Windows Share]
- Fixed an issue which was impacting Windows share window reliability for some Insiders.
NOTE: Some fixes noted here in Insider Preview builds from the Dev Channel may make their way into the servicing updates for the released version of Windows 11.
Known issues
[Copilot in Windows*]
- When first launching or after refreshing Copilot in Windows while using voice access, you’ll need to use “Show grid” commands to click in the “Ask me anything” box for the first time.
[Widgets]
- Announcements from the Microsoft Start feed are still shown on the taskbar after the feed is hidden.
- Keyboard navigation from settings subpages back to the top-level Settings page is broken.
- Incorrect spacing and fonts used in some settings pages.
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:
- .NET TFM packages for use in .NET apps as described at aka.ms/windowsinsidersdk
- C++ packages for Win32 headers and libs per architecture
- BuildTools package when you just need tools like MakeAppx.exe, MakePri.exe, and SignTool.exe
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.
