KB5079385

Microsoft released cumulative update KB5079385 for Windows 11, version 25H2 for insiders on the Dev channel – Windows 11 Insider Preview Quality Update (26300.7965). The preliminary build Windows 11 Insider Preview Build 26300.7965 (KB5079385) was released. Users of this channel will now receive Windows 11, version 25H2 updates, which are available using the enablement package KB5073032 (build 26300.xxx).

• Administrator protection. In Windows 11 Insider Preview Build 26300.7965 (Dev Channel), Microsoft re-enables the Administrator protection feature. It is designed to protect administrative rights and reduce risks associated with permanent administrator rights on the system. The feature provides a just-in-time administrative privilege model. This means a user with administrator rights can perform administrative actions, but privileges are granted only for the duration of a specific operation. This reduces the risk of abuse or compromise of administrative rights by malicious software. The feature is disabled by default. Administrators can enable it via OMA-URI in Microsoft Intune or using Group Policies.
• File sharing (Drag tray improvement). Based on user feedback, Microsoft refined the Drag tray interface. A more compact peek view is now used, reducing the chance of accidental panel appearance and making it easier to close when working near the top of the screen.
• File Explorer (voice input when renaming). When renaming files in File Explorer, you can now use voice input (Win + H).
• File Explorer (fix for white flashes). Fixed a white flash when opening new File Explorer windows or tabs if it is set to open the “This PC” section. Also fixed white flashes when resizing File Explorer interface elements.
• File Explorer (file unlocking reliability). Improved reliability of unlocking files downloaded from the internet so they can be correctly viewed in the File Explorer preview pane.

Installation via Windows Update: go to Settings > Windows Update and click Check for updates. A computer restart is required to complete installation.

Features and capabilities that are included in Dev channel builds may never appear in the final release, as Microsoft actively tests different concepts and gathers feedback. Features may change, be removed, or be replaced and may not leave the Windows Insider program. Some of them may appear in future versions of Windows when fully ready.

Some prerelease features may not be fully localized in all languages. Localization will gradually improve as feature development completes. If you notice translation issues for your language, report them through the Feedback Hub.

Please note that some accessibility features may temporarily not work with prerelease features such as Recall and Click to Do.

Since the Dev and Beta channels represent parallel development tracks, there are cases where some features and capabilities appear first in the Beta channel.
