Key Points
- Microsoft released Windows 11 Insider Preview Build 26300.8142 to the Dev Channel, introducing new Administrator Protection settings and touchpad customization options.
- Task Manager received significant updates, including new columns to monitor neural processing unit usage and application isolation contexts.
- Features are rolled out gradually through a controlled system, and Insiders are reminded that preview builds may change or not be included in final releases.
Microsoft has released Windows 11 Insider Preview Build 26300.8142 (KB 5079492) to participants in the Dev Channel. This pre-release build delivers several enhancements focused on security, input devices, and system monitoring. The update is part of the ongoing Windows Insider Program, which tests new concepts with a community of users before potential inclusion in future Windows updates.
One major addition is the expanded rollout of Administrator Protection. After previously enabling this feature for IT administrators, Microsoft now allows all Dev Channel Insiders to turn it on. The setting is located in Settings under Privacy & security, then Windows Security, and finally Account protection. Users must toggle the switch on and restart their device to activate the protection. This feature is designed to add a layer of security for administrative tasks.
For touchpad users, a new customization option is available. A setting in Settings > Bluetooth & Devices > Touchpad now lets users select the size of the right-click zone. This is the area in the bottom-right corner of the touchpad where a single press registers as a right-click. Options include default, small, medium, and large sizes. The setting only appears on touchpads with a pressable surface. If a user has already customized this area through a manufacturer’s app, the dropdown will show a "Custom" entry to preserve that configuration.
Task Manager has been updated with several new optional columns to provide deeper system insights, particularly for devices with a neural processing unit (NPU). Users can now add columns for overall NPU usage and NPU Engine activity on the Processes, Users, and Details pages. The Details page specifically adds columns for NPU Dedicated Memory and NPU Shared Memory. Furthermore, neural engines that are part of a GPU will now appear on the Performance page, giving a more complete view of AI-related activity. An additional new column, Isolation, shows which applications are running within an AppContainer, a security sandboxing technology. These columns can be enabled by right-clicking any column header in Task Manager and selecting them from the menu.
A minor visual update introduces a new icon for Windows Protected Print Mode. The build also addresses an accessibility issue that previously impacted the use of Braille displays for some Insiders.
The release highlights the controlled nature of feature distribution within the Dev Channel. Microsoft uses Controlled Feature Rollout technology, meaning new features first reach a small subset of Insiders. The rollout expands over time based on feedback and stability monitoring. Insiders who enable the toggle to get the latest updates as they are available via Settings > Windows Update will receive features sooner. Those who keep the toggle off will get updates more gradually as they become ready for broader deployment.
Microsoft emphasizes that features in Dev Channel builds are experimental. They may change significantly, be removed entirely, or never progress beyond the Insider program. Some may appear in future Windows releases when finalized, but there is no guarantee. Localization for these developing features is also incomplete and will improve over time. Users are encouraged to report any localization issues through the Feedback Hub.
Insiders should be aware that pre-release builds display a permanent desktop watermark in the lower-right corner. For a comprehensive view of which features are available in specific Insider channels, Microsoft directs users to the Flight Hub page.
This build gives Dev Channel participants an early look at practical improvements in device security, input flexibility, and system resource monitoring. The focus on NPU tracking reflects the growing role of AI accelerators in modern PCs. The gradual rollout model means not all Insiders will see every change immediately. Those interested in the latest features should ensure their toggle is enabled and use Feedback Hub to report their experiences, as this input directly influences the development path of these tools.
