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.

How does Core Isolation protect your Windows 11 System?

Core Isolation Functionalities

• Enhanced Protection : Core Isolation provides an additional layer of protection by ensuring that critical system processes run in a secure environment, making it harder for attackers to compromise the Windows 11 kernel.
• Prevention of Code Injection Attacks : By verifying that only signed and trusted code can execute in the system’s kernel, Core Isolation helps prevent code injection attacks, which are a common method used by malware to take control of a system.
• Improved Security for Virtual Machines : For users running virtual machines, it ensures that each VM has its own protected memory space, enhancing overall security in virtualized environments.
