Splits memory into Virtual Trust Levels (VTLs). VTL 0 hosts the standard Windows kernel, while VTL 1 hosts an isolated, high-security microkernel. Hypervisor-Protected Code Integrity (HVCI)

Understanding the Windows 10 1809 Kernel: Architecture, Isolation, and Enterprise Features

HVCI ensures that all kernel-mode drivers and system code are cryptographically signed and verified before execution. The VTL 1 memory manager sets memory page permissions strictly: a page can be writable or executable, but never both simultaneously (W^X enforcement). This defense mechanism blocks common kernel exploitation techniques, such as buffer overflows designed to inject and execute arbitrary code inside Ring 0.
