Announcing Windows 11 Insider Preview Build 23419

Hello Windows Insiders,

Today we are releasing Windows 11 Insider Preview Build 23419 to the Dev Channel. We are releasing ISOs for this build – they can be downloaded here.

What’s new in Build 23419

Create live kernel memory dumps in Task Manager

We are introducing a set of new developer-focused features in Task Manager to aid the collection of live kernel memory dumps (LKDs). This is in addition to the existing “Memory dump” for user mode processes. The goal of kernel live dump is to gather data to troubleshoot an abnormal situation but allow the OS to continue operation. This reduces downtime when compared to a bug check for “non-fatal” but high-impact failures and hangs. Click here for more info on live kernel dumps.

To capture a live kernel memory dump (LKD), go to the Details page in Task Manager, right-click on the System process and the context menu should light up to show “Create live kernel memory dump file” to capture a Full live kernel or Kernel stack memory dumps.

The dumps will be written to a fixed location:

%LocalAppData%\Microsoft\Windows\TaskManager\LiveKernelDumps

You can also go to the Task Manager Settings page to view/edit the settings for live kernel memory dumps.

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Desktop Environment > Task Manager.

USB4 Settings Page

We are adding a USB4 hubs and devices Settings page for users under Settings > Bluetooth & devices > USB > USB4 Hubs and Devices. USB4 enables new productivity scenarios for docking, high performance peripherals, displays and charging. The USB4 settings page provides information about the system’s USB4 capabilities and attached peripherals on a USB4 capable system. These insights are meant to assist with troubleshooting in case users need support from their device manufacturer (OEM) or system administrator. The features provided by this page are:

If the system does not support USB4 with the Microsoft USB4 Connection Manager, this page will not be displayed.

To confirm whether your system is USB4 capable or not, check for “USB4 Host Router” populating in the Device Manager.

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Devices and Drivers > Buses.

Cloud Suggestion in Simplified Chinese IME

We are trying out some changes that will allow you to easily type popular words in Simplified Chinese. The changes include an improved cloud suggestion and integrated search suggestion. The cloud suggestion adds the most relevant word from Bing to the IME candidate window. We’ve updated the back-end logic so that we can provide better, fresh suggestions.

The integrated search suggestion gives you additional suggestions that are similar to what you see in Bing search page. You can either insert a suggestion as text or search it directly in Bing.

To turn on these features, select a chevron button at the right end of the IME candidate window. You’ll find Turn on button.

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Input and Language > Text Input.

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 are being 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.
