[KB5022910] WHAT'S NEW in Windows 11 Build 22621.1537 & 22624.1537?

This week, Microsoft released builds 22621.1537 and 22624.1537 (KB5022910) to the Beta Channel for Windows 11 Insiders.

Build 22624.1537 = New features rolling out.
Build 22621.1537 = New features off by default.
REMINDER: Insiders who were previously on Build 22623 will automatically get moved to Build 22624 via an enablement package. The enablement package artificially increments the build number for the update with new features getting rolled out and turned on to make it easier to differentiate from devices with the update with features off by default. This approach is being used for the Beta Channel only and is not indicative of any changes or plans for final feature rollouts.

➤ FULL CHANGELOG HERE:

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.]

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

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.

[Taskbar & System Tray]
We fixed the issue in the previous build where the option under Settings / Personalization / Taskbar in the Taskbar behavior section to show seconds in the clock on the system tray was not actually enabling the functionality. Enabling should work now.
