Insider KB5079492 Windows 11 Insider Dev build 26300.8142 (25H2) - March 30

UPDATE 4/03:



Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 26300.8142 (KB 5079492) to the Dev Channel.

Changes in Dev Channel builds and updates are documented in two buckets: new features, and improvements (including notable fixes) that are being gradually rolled out for Insiders who have turned on the toggle to get the latest updates as they are available (via Settings > Windows Update*) and then new features, and improvements (including notable fixes) rolling out to everyone in the Dev Channel. For more information, see the Reminders section at the bottom of this blog.

Changes and Improvements gradually being rolled out with toggle on*​

[Administrator Protection]​

• After resuming the rollout of Administrator Protection as enabled by IT admins, we are also now rolling out the ability to enable Administrator Protection in Settings under Privacy & security > Windows Security > Account protection and switching the toggle to on. A restart will be required.

[Touchpad]​

• We’re adding a new setting in Settings > Bluetooth & Devices > Touchpad so you can choose how large the right-click zone size is (this is the portion in the bottom-right of your touchpad where pressing a single finger will result in a right-click), between default, small, medium, and large. Note – this setting only appears for touchpads that have a pressable surface for this. Some manufacturers may provide customization for this in their own apps – if you’ve customized your setting using an app like this, a “Custom” entry will be added to the dropdown, which preserves that value.

[Task Manager]​

We’re making a few improvements to Task Manager:

• We’re updating Task Manager to provide better insight into NPU usage for PCs that include an NPU. New optional NPU and NPU Engine columns are now available on the Processes, Users, and Details pages. The Details page also adds NPU Dedicated Memory and NPU Shared Memory optional columns to give you deeper visibility into how workloads are using NPU resources. Additionally, if there are neural engines that are part of a GPU, they will now appear on the Performance page, providing a more complete view of AI‑related system activity.

Reminders for Windows Insiders in the Dev Channel​

• Updates are based on Windows 11, version 25H2 via an enablement package (Build 26300.8142).
• Many features are rolled out using Controlled Feature Rollout technology, starting with a subset of Insiders and ramping up over time as we monitor feedback to see how they land before pushing them out to everyone in this channel.
• The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.
• For Windows Insiders who want to be the first to get features gradually rolled out to you, you can turn ON the toggle to get the latest updates as they are available via Settings > Windows Update*. Over time, we will increase the rollouts of features to everyone with the toggle turned on. Should you keep this toggle off, new features will gradually be rolled out to your PC over time once they are ready.
• Features and experiences included in these builds may never get released as we try out different concepts and get feedback. Features may change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they’re ready.
• Some features in active development we preview with Windows Insiders may not be fully localized and localization will happen over time as features are finalized. As you see issues with localization in your language, please report those issues to us via Feedback Hub.
• Check out Flight Hub for a complete look at what build is in which Insider channel.

Thanks,
Windows Insider Program Team
