Windows 11 Insider Preview Build 26300.7939 is now available in the Dev Channel. Key additions include enhanced security for batch file processing via a new LockBatchFilesInUse registry setting that prevents file modification during execution and reduces signature validation overhead. Shared audio (preview) gains per-listener volume sliders and a taskbar indicator, with new device support including Samsung Galaxy Buds 4, Sony WF-1000XM6, and Xbox Wireless Headset. Narrator gets a new status bar reading command, and there are reliability improvements for taskbar autohide animations, storage cleanup, and ADLaM keyboard input.
