Windows 11 409 Published by

Microsoft has released both Windows 11 Insider Preview Builds 22621.1537 and 22624.1537 to Windows insiders in the beta channel.





Announcing Windows 11 Insider Preview Build 22621.1537 and 22624.1537

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 22621.1537 and Build 22624.1537 (KB5022910) to the Beta Channel. 

What’s new in Build 22624.1537

Access Keys in File Explorer

We are adding access key shortcuts into the XAML context menu in File Explorer. An access key is a one keystroke shortcut that allows a keyboard user to quickly execute a command in context menu. Each access key will correspond with a letter in the display name. It’s part of our effort to make File Explorer more accessible. To try this out, you can click on a file in File Explorer and press the  menu key on your keyboard.

[We are beginning to roll this out, so the experience isn’t available to all Insiders in the Beta Channel just yet as we plan to monitor feedback and see how it lands before pushing it out to everyone.]

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Files, Folders, and Online Storage > File Explorer.

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.

Content Adaptive Brightness Control (CABC) on plugged in devices including desktop PCs

Content Adaptive Brightness Control (CABC) is already a feature that users are familiar with. This feature in Windows 11 will dim or brighten areas of a display or monitor based on the content being displayed with the goal of striking a balance between reduced power consumption with visual experience to save battery life. Starting with this build, we are allowing this feature to run on devices such as laptops and 2-in-1’s that are plugged into a charger, as well as on desktop PCs. For most users, this change won’t be noticeable and should reduce energy consumption.

This feature can be adjusted via Settings > System > Display under “Brightness & color” and through a drop-down menu with 3 options: Off, Always, and “On Battery Only”. For battery powered devices such as laptops and 2-in-1’s, the default is “On Battery Only”. On desktop PCs, this is off by default. We encourage Insiders across laptops, 2-in1’s, and desktop PCs to try the  “Always” option and give us feedback on the visual quality of CABC so we can ensure it is properly tuned.

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