Microsoft’s Windows 11 Insider Preview builds introduce a secure batch processing mode that prevents batch files from being modified during execution, configurable via the LockBatchFilesInUse registry value or the LockBatchFilesWhenInUse application manifest control. The update also improves performance by reducing signature validation overhead when code integrity is enabled and enhances Shared Audio with individual volume sliders, a taskbar indicator, and expanded Bluetooth LE Audio support. #Windows11 #LockBatchFilesInUse
