How to Enable Core Isolation in Windows 11?

Enable Memory Integrity, also known as Hypervisor-protected Code Integrity (HVCI)


Enable Core Isolation in Windows 11: Core Isolation protects critical parts of the  Windows 11 operating system from attacks by using virtualization-based security (VBS). This creates a secure environment where essential system processes can run separately from the rest of the OS, making it much harder for malware to interfere. A key part of Core Isolation is Memory Integrity, also known as Hypervisor-protected Code Integrity (HVCI). Memory Integrity ensures that only trusted, signed drivers and system files can run, blocking unauthorized code from accessing the kernel. This prevents many common attacks that rely on injecting malicious code. Let’s go through the steps of enabling Core Isolation in Windows 11.

  • Open Windows Settings using Win Key + I
  • Click on Privacy and Security.
