Since "HVCI" can refer to a few different technical concepts (mostly in cybersecurity and Windows operating systems), I have provided a detailed breakdown of the most common meaning below. It looks like you are looking for an

If you were looking for a different HVCI (e.g., a specific company stock ticker, a medical term, or an academic journal), please let me know. What is HVCI? HVCI stands for Hypervisor-Protected Code Integrity . It is a critical security feature built into modern versions of Microsoft Windows (Windows 10, Windows 11, and Windows Server 2016/2019/2022). Sometimes referred to as Memory Integrity , HVCI uses hardware virtualization to isolate the Code Integrity (CI) decision-making process from the rest of the operating system. HVCI stands for Hypervisor-Protected Code Integrity

In simple terms, HVCI ensures that only signed, trusted, and well-behaved code (drivers and system files) can run inside the Windows kernel. If malicious or untrusted code tries to execute, HVCI blocks it. Traditional Code Integrity runs inside the Windows kernel. If a hacker compromises the kernel, they can often disable code integrity checks. HVCI solves this by running the code integrity service inside a virtualized secure environment (a Virtual Secure Mode, or VSM), separate from the main OS kernel. In simple terms, HVCI ensures that only signed,
