Microsoft testing Windows 11 batch file security improvements

Microsoft has released new Windows 11 Insider Preview builds that enhance security and performance for batch files and CMD scripts. IT administrators can now activate a secure processing mode by adding the LockBatchFilesInUse registry value, which prevents modifications to batch files while they are running. This update also requires signature validation only once per batch file, improving performance. Additionally, the Shared Audio feature has been refined, allowing users to share audio across multiple devices with individual volume sliders and a new taskbar indicator. The feature now supports more Bluetooth LE Audio accessories, including Samsung Galaxy Buds 4, Sony WF-1000XM6, and Xbox Wireless Headset. These updates are available for Windows Insiders in the Beta and Dev channels with specific preview builds installed.
