Written By published August 31, 2023

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 23536 to the Dev Channel.

Fixes

[Windows Copilot]

  • Fixed an issue that was causing the Windows Copilot icon in the taskbar to be flipped backwards for right-to-left languages.

[Taskbar]

  • Fixed an explorer.exe crash impacting taskbar appearing correctly after powering on your device.
  • Fixed an issue which was causing apps in the taskbar to appear cut off without a rounded corner on the end when you had a lot of app windows open, and the taskbar was set to not combine.

[Live captions]

  • Fixed an issue that was causing live captions to sometimes show the same line of text twice.

[Input]

  • Fixed a high hitting ctfmon.exe crash in recent flights, which may have impacted the ability to type for some Insiders.

[Settings]

  • Did some work to help improve the performance of opening Settings for Insiders with the new Home page.

[Task Manager]

  • Fixed an issue that could cause Task Manager to crash when using the end task option in the Details page recent builds.

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

[Start menu]

  • Some apps under All apps on the Start menu, such as PWA apps installed via Microsoft Edge, may incorrectly be labeled as a system component.

[Search on the Taskbar]

  • Sometimes the tooltip when mousing over the search box does not match the current search highlight.

[Input]

  • [NEW] Unicode Emoji 15 support which began rolling out with Build 23475 and the updated color font format with COLRv1 support that began rolling out with Build 23506 no longer appear after updating to Build 23531 due to a bug. This issue will be fixed in a future flight soon.

[Windows Copilot]

  • You can use Alt + Tab to switch out of Windows Copilot, but not back into it. Windows + C will move focus back to Windows Copilot
  • When first launching or after refreshing Copilot while using voice access you’ll need to use “Show grid” commands to click in the “Ask me anything” box for the first time.

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.
