Windows 11 Build 25276 Released: New Task Manager Feature

Windows 11 Build 25276 is now available in the Dev Channel of the Windows Insider Program. This is the second preview update this year. It brings new features such as the ability to create live kernel memory dumps in Task Manager and improvements to OneDrive cloud storage in Windows 11 Settings.

Build 25276 is not tied to any particular Moment or feature update, as Microsoft calls those updates “standalone.” Microsoft has also released an ISO image of Windows 11 Build 25276 that can be used to directly update any Windows 10, 11, or even Windows 7 PC to this build.

It’s worth noting that Build 25276 isn’t a big release, nor does it bring a ton of new features, but you’ll notice a couple of notable changes. Creating live kernel memory dumps in Task Manager is one of the new “developer-focused” features, and more such changes are coming.

Microsoft says the feature helps with the operating system’s existing Live Kernel Dump (LKD) feature. This feature is an extension to a troubleshooting feature called “memory dumping” for user-mode processes. For those who don’t know, this feature is useful because it helps you gather data to rule out anomalies.

For example, you can use it to find out what went wrong when Windows won’t start, or how a specific driver is preventing a specific function on your system. To use this tool, just open the Task Manager > Details page and right-click on the system process, there is a new option called “Create Live Kernel Memory Dump File”.

When you click on that option, it will capture a full live kernel or kernel stack memory dump. You can find dumps in the LiveKernelDumps folder.

Settings for Live Kernel Memory Dump can also be edited by navigating to the Task Manager settings page.
