Windows 11 Build 25276 is now available for PCs in the Dev Channel of the Windows Insider Program. It is the second preview update of the year, and it includes a couple of new additions, such as the ability to create live kernel memory dumps in Task Manager and improvements to OneDrive storage in settings for Windows 11.
Build 25276 is not tied to any specific Moment or feature updates, as Microsoft says these updates are “independent”. Microsoft has also published ISO images of Windows 11 Build 25276, which can be used to directly update any Windows 10, 11 or even Windows 7 PC to this build.
It is worth noting that Build 25276 is not a big release, and it doesn’t come with tons of new features, but you’ll notice several noticeable changes. For example, Microsoft is introducing the ability to create live kernel memory dumps in Task Manager. This is one of the new “developer-focused” features, and more such changes are coming.
Microsoft says the feature aids the existing live kernel memory dumps (LKDs) functionality of the OS. This feature is an extension of the troubleshooting feature called “Memory dump” for user mode processes. For those unaware, this feature is beneficial because it helps you gather data to troubleshoot an abnormal situation.
For example, you can use it to find out what went wrong when Windows failed to boot or how a specific driver prevented a particular feature on the system. To use this tool, simply open Task Manager > Details page and right-click on the System process, which contains a new option called “Create live kernel memory dump file”.
When you click on the option, it will capture a Full live kernel or Kernel stack memory dumps. You can find the dump LiveKernelDumps folder.
It is also possible to edit settings for live kernel memory dumps by navigating to Task Manager Settings page.

Microsoft is now introducing a new addition that lets you view Outlook attachment data in your cloud storage. This change is still rolling out and will appear on some PCs, so not everyone will see it today.
Other cosmetic improvements include a new design for Windows’s “compatibility dialog” feature.
Microsoft is rolling out a new look for the popup/alert that shows up when Windows detects a known compatibility issue. This dialog now uses Windows 11’s Fluent design.
