Create live kernel memory dumps in Task Manager
Microsoft is 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.
Updates to Cloud Storage in Settings for Windows 11
In November, Microsoft introduced a visual overview of your cloud storage usage in Settings app. You will see updates to the Microsoft 365 apps and service data included in your cloud storage. Outlook attachment data will be included in your cloud storage as displayed on the visual with today’s build. This change will gradually roll out starting with a small number of insiders, so not everyone will see it right away. You may see an alert regarding your storage usage; however, it does not impact your storage amount as early as February 1st, 2023. Learn more about cloud storage here.
New Dialog
Microsoft has updated the dialog that shows when an app has a known compatibility issue to use the new Windows 11 design.
Windows Security Changes
- We are temporarily disabling the updated the Windows Security (firewall) notification dialogs that match the Windows 11 visuals that we introduced with Build 25267. We plan to re-introduce this change in a future flight after addressing some bugs.
- Windows 11 Insider Preview Build 25267 and later Pro editions no longer allow a user to connect to a remote share by using guest credentials by default, even if the remote server requests guest credentials. This matches the stronger security of the Enterprise and Education editions that’s been in place since Windows 10, to further improve Windows 11 default security. For more information on this behavior and to configure insecure guest authentication to a third party SMB server device that only supports guest authentication, review this documentation.
New Apple Apps in Windows 11
Previews of the Apple Music, Apple TV and Apple Devices apps are available in the Microsoft Store on Windows 11, limited to the U.S.
Get Help App: Troubleshoot network issues
Getting disconnected from the internet hurts productivity at work and relaxation at home. To help you get back online we’re replacing the Network Troubleshooter in the OS with a modern Get Help based experience. With new APIs that diagnose problems and offer specific recommendations to get online, the app targets the 30 most common connectivity issues. To use the new experience, you will need Get Help app version 10.2208.2551.0 or greater.
Fixes in this Build
Taskbar and System Tray
- Fixed an issue where switching windows through taskbar previews wasn’t working.
- Fixed multiple explorer.exe crashes affecting the system tray.
- When opening a flyout from the taskbar, pressing the Esc key to close the flyout should now return keyboard focus to the button it was invoked from.
Search on the taskbar
- We fixed the layout issues with the text in the search box on taskbar when using right-to-left display languages like Arabic.
- Fixed an issue where the selected search style in Taskbar Settings wasn’t persisting across updates. This setting should persist now on subsequent Insider Preview build upgrades.
File Explorer
- Fixed an explorer.exe crash which could happen when opening File Explorer, related to loading your recent files.
Voice Access
- Voice access will now work correctly for entering numbers in the Calculator app.
- Fixed a crash when giving move left and right commands with voice access.
Input
- Fixed an issue where the “insert text” button wasn’t working when using the Pinyin IME in double pinyin mode.
Widgets
- Fixed an issue where the widgets board will get stuck open in an invisible state for Insiders in China (and potentially others), causing clicks on the left side of the screen to not work. If you’re continuing to experience this, please make sure to check the Microsoft Store for the latest app updates.
Other
- To improve clarity, when Windows Defender Credential Guard is enabled, when attempting to use remote desktop with default credentials, it will now explicitly say “Windows Defender Credential Guard does not allow using Windows logon credentials. Please enter your credentials”.
