    Windows 11 Batch File Security Improvements in Insider Preview

    Microsoft is rolling out new Windows 11 Insider Preview builds that improve security during batch file or CMD script execution. IT administrators can enable a more secure processing mode by adding the LockBatchFilesInUse registry value under HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor. Policy authors can enable this mode using the LockBatchFilesWhenInUse application manifest control. The new mode ensures batch files do not change during execution, enhancing performance and security by requiring signature validation only once.
