Part 1: What Is HVCI for Valorant?

HVCI, or Hypervisor-Protected Code Integrity, is a Windows security feature that uses hardware virtualization to prevent unauthorized code from running in the operating system kernel. In simple terms, it helps protect your system from low-level malware and ensures only verified drivers and programs can execute. Valorant relies on a secure environment to maintain fair gameplay, which is why enabling HVCI is sometimes required for proper operation.

Key features of HVCI for Valorant:

• Protects system memory from malicious code injection
• Strengthens kernel-level security enforcement
• Works alongside virtualization-based security
• Prevents unsigned drivers from loading
• Supports Riot Vanguard anti-cheat compatibility
• Enhances overall system integrity during gameplay

Understanding this security layer helps explain why many players look up how to enable HVCI for Valorant when troubleshooting launch errors

Part 2: How To Enable and Disable HVCI Valorant?

Configuring HVCI depends on your Windows version. Below are detailed methods for enabling HVCI on Windows 10 and Windows 11, and for disabling HVCI if needed for troubleshooting or compatibility reasons.

How To Enable HVCI Valorant in Windows 10

If you’re using Windows 10, enabling HVCI requires turning on Memory Integrity through Windows Security. 

Follow these steps carefully:

Step 1. Press Windows + I to open Settings.

Step 2. Navigate to Update & Security.

Step 3. Click Windows Security in the left sidebar.

Step 4. Select Device Security.

Step 5. Under Core Isolation, click Core isolation details.

Step 6. Toggle Memory Integrity to ON.

Step 7. Restart your computer to apply changes.

After rebooting, launch Valorant to verify that the security requirement is satisfied. If you previously searched for hvci enable valorant solutions, this is typically the method recommended by system security prompts.

If Memory Integrity cannot be enabled, it usually means an incompatible driver is installed. Updating or removing conflicting drivers often resolves the issue.

How To Enable HVCI Valorant in Windows 11

Windows 11 integrates security features more tightly, but the process remains straightforward. Here’s how to enable HVCI Valorant Windows 11:

Open Settings from the Start menu.

Step 1. Go to Privacy & Security.

Step 2. Select Windows Security.

Step 3. Click Device Security.

Step 4. Under Core Isolation, open Core isolation details.

Step 5. Turn on Memory Integrity.

Step 6. Restart your system.

Once your system reboots, Valorant should recognize the secure environment automatically. Many players searching for how to enable HVCI Valorant Windows 11 discover that this setting resolves Vanguard security warnings instantly.

If the toggle is unavailable, ensure virtualization is enabled in BIOS and that your system supports hardware virtualization.

How to Disable HVCI Valorant?

In some cases, users may need to disable HVCI due to performance concerns, compatibility issues, or troubleshooting steps recommended by support teams. While security is important, temporarily disabling HVCI can help identify whether it’s causing conflicts.

To disable HVCI Valorant:

Step 1. Open Settings.

Step 2. Navigate to Windows Security.

Step 3. Click Device Security.

Step 4. Select Core isolation details.

Step 5. Toggle Memory Integrity to OFF.

Step 6. Restart your computer.

Disabling HVCI reduces kernel-level protection, so it should only be done when necessary. If your system struggles with stability or driver compatibility, this method can help diagnose the issue before re-enabling security features.
