Improvements: Enhanced the security of the Windows system.

[PPL Protection]

Users can bypass relevant settings.

ProtectedProcessLight (PPL) is a security mechanism introduced in Windows 10 to enhance the security of processes to resist malicious code attacks and data leaks. PPL is a process protection technology that divides the trustworthiness of processes into four levels, each with corresponding security features and limitations.

[Windows Kernel Vulnerability Driver Block List File (DriverSiPolicy.p7b)]

Updated the driver list and added the list of files with the risk of built-in vulnerability driver (BYOVD) attack.

[BitLocker (Known Issue)]

The BitLocker recovery screen will be displayed when starting the device. This situation occurs after installing the July 9, 2024 update. If device encryption is turned on, this problem is more likely to occur.

[Lock Screen]

This update solves the problem of CVE-2024-38143: The Use My Windows User Account checkbox is not available when connecting to Wi-Fi on the lock screen.

[NetJoinLegacyAccountReuse]

This update removed this registry key value.

[SBAT and EFI]

This update applies Secure Boot Advanced Targeting (SBAT) to systems running Windows. This will prevent vulnerable Linux EFI (Shim boot loader) from running.

This SBAT update does not apply to systems with dual-boot of Windows and Linux. After applying the SBAT update, older Linux ISO images may not be able to start. If this happens, users need to contact the Linux vendor to obtain the latest ISO image.
