Microsoft has released Windows 11 Insider Preview Build 23419 for Windows Insiders on the dev channel. As well as being available via Windows Update Microsoft have also made an ISO available for performing clean installs of Windows 11.

The main change is for developers: The update has Live Kernal memory dumps in Task Manager which will enable devs to debug their code.

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:


Microsoft are improving support for USB4:

For Insider with USB4 devices Microsoft have added a new Setting page (Settings > Bluetooth & devices > USB > USB4 Hubs and Devices). If you don’t have a USB4 device connected you will not see the new setting.

An other change Microsoft is trying out for a few insiders is the renaming of the Recommended section of the start menu to For You.

There is the VPN status on the network icon in the system tray and the abiltiy to show seconds in the system tray clock:

There is also a new Bing chat button in the search box as well as an updated in-app help page included in the 23403.

Here are the fixes and known issues in build 23419:



  • Improved the experience on logon after booting up by reducing the performance impact of startup apps.

[Taskbar & System Tray]

  • Fixed an issue that was causing Narrator to read the position before the name on system tray icons.
  • Fixed an issue causing the show hidden icons flyout to open behind things like OneNote flyout and live captions.
  • Fixed an issue which could cause explorer.exe crashes related to drag and drop.

[Search on the Taskbar]

  • Fixed a search crash from the last flight.

[File Explorer]

  • Fixed an issue which could cause explorer.exe to crash when opening Home if certain content was visible in the Recent section.
  • Made some improvements to the performance of loading File Explorer in the case where there’s a disconnected network drive visible in the navigation pane.

[Start menu]

  • Fixed an issue where dragging content across an open Start menu folder could cause a crash.


  • Fixed an issue where after using voice typing your PC might not enter modern standby.

[Live captions]

  • We fixed the issue causing live captions to not work for Chinese Traditional on Arm64 devices.

[Task Manager]

  • Fixed an issue where some of the details in the Performance page wouldn’t display properly until you resized the window or changed pages back and forth.

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

[Search on the Taskbar]

  • There is an issue where some people may not see the search box on taskbar and/or the settings to adjust the search box experience on the taskbar after updating to Build 23403. We are aware of the issue, and we are working on a fix.

[File Explorer]

Insiders who have access keys in File Explorer:

  • Access keys will appear inconsistently if no button is pressed. Pressing a button will cause them to reappear.

Insiders will have issues with the following commands on recommended files in File Explorer:

  • Clicking on the Share command will currently bring up the Windows share sheet (non-OneDrive).
  • Clicking on the “Open File Location” command will pop an error dialog that can easily be dismissed.
  • Clicking on the ‘Remove from list’ command will result in no actions.

[Live captions]

  • On ARM64 devices, enhanced speech recognition support installed through the Language & Region settings page will require restarting live captions if you switch languages in the live captions Caption language menu.
  • Certain languages shown on the Language & Region settings page will indicate speech recognition support (e.g., Korean) but don’t yet have support for live captions.
  • When adding a language through the Language & Region settings page, language feature installation progress may become hidden, and you may not see install completion of “Enhanced speech recognition” (required by Live Captions). (You can use the language’s “Language options” to monitor progress.) If this happens, there may be an unexpected delay before the live caption setup experience detects this and lets you continue.
  • Captioning performance may be degraded in non-English languages and missing out-of-language filtering in non-English (United States) languages which means that incorrect captions will be shown for speech not in the caption language.
