How to Disable VBS in Windows 11 for Better Performance

Virtualization-Based Security (VBS) is a security feature in Windows 11 designed to protect sensitive data and system integrity. However, some users may experience performance issues, compatibility problems, or simply prefer to disable VBS for troubleshooting or specific use cases. Disabling VBS can improve system responsiveness and reduce resource consumption, especially on older hardware or when running certain applications that conflict with this security layer. Before proceeding, ensure you understand the implications of disabling security features, as it can potentially expose your system to vulnerabilities. This guide provides a clear, step-by-step process to disable VBS in Windows 11 safely and effectively.

What You’ll Need

• A Windows 11 administrator account
• Access to Group Policy Editor or Registry Editor
• Optional: Backup your system before making significant changes

Step-by-Step

1. Open the Settings app: Click on the Start menu and select the gear icon or press Windows + I to open Settings.
2. Navigate to System > Recovery: In the Settings window, go to ‘System’ on the left sidebar, then click on ‘Recovery’.
3. Access Advanced Startup Options: Under the ‘Advanced startup’ section, click on ‘Restart now’. This will reboot your PC into a special menu.
4. Enter Troubleshoot Menu: After restart, select ‘Troubleshoot’ > ‘Advanced options’ > ‘Startup Settings’ > ‘Restart’.
5. Disable VBS via Registry or Group Policy: Once your system restarts, choose the method below to disable VBS.
6. Method 1: Using Registry Editor:
   • Press Windows + R, type ‘regedit’, and press Enter to open Registry Editor.
   • Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard
   • Locate the ‘EnableVirtualizationBasedSecurity’ DWORD value. If it doesn’t exist, create it.
   • Double-click on ‘EnableVirtualizationBasedSecurity’ and set the value to 0.
   • Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
   • Find ‘RunAsPPL’ and set it to 0 if it exists.
   • Close Registry Editor and restart your PC to apply changes.
7. Method 2: Using Group Policy Editor:
   • Press Windows + R, type ‘gpedit.msc’, and press Enter.
   • Navigate to Computer Configuration > Administrative Templates > System > Device Guard.
   • Double-click on ‘Turn On Virtualization Based Security’.
   • Set it to ‘Disabled’ and click ‘Apply’ then ‘OK’.
   • Close Group Policy Editor and restart your PC.

Common Mistakes

• Not backing up your system before making registry or group policy changes—this can lead to issues if something goes wrong.
• Forgetting to restart after applying changes—VBS won’t be disabled until the system restarts.
• Modifying the wrong registry keys or settings—ensure you’re editing the correct entries to avoid system instability.
• Disabling security features without understanding the risks—this can expose your system to vulnerabilities.
• Assuming VBS disables automatically after setting changes—manual restart is required for changes to take effect.

Tips

• Always create a system restore point before editing registry or group policy settings.
• If you’re unsure about editing the registry, use the Group Policy method as it provides a safer, GUI-based approach.
• Check your system’s security settings after disabling VBS to ensure no unintended vulnerabilities are introduced.
• Disabling VBS may affect features like Hyper-V or Windows Defender Application Guard—consider these impacts before proceeding.
• If you encounter issues after disabling VBS, re-enable it by reversing the steps outlined above.

Troubleshooting

If disabling VBS does not go as planned or you experience system instability, try the following:

• Revert changes: Use the registry or group policy method to re-enable VBS by setting the appropriate values back to ‘1’ or ‘Enabled’.
• Run System File Checker: Open Command Prompt as administrator and run ‘sfc /scannow’ to repair corrupted system files.
• Check for Windows updates: Ensure your system is up-to-date, as updates can fix bugs related to security features.
• Use System Restore: Restore your system to a point before the changes if problems persist.
• Consult Event Viewer: Look for error logs related to security settings to identify underlying issues.

Frequently Asked Questions

• Can I disable VBS safely? Yes, but be aware it reduces some security protections. Only disable if necessary and understand the risks.
• Will disabling VBS affect my Windows 11 performance? Potentially, especially if VBS was causing performance issues. It may improve responsiveness in some cases.
• Is it possible to re-enable VBS later? Absolutely. Just follow the same steps and set the relevant registry keys or group policy settings back to enabled.
• Does disabling VBS impact Windows Defender? Not directly, but some security features like Credential Guard rely on VBS, so they may be affected.
• What security risks do I face after disabling VBS? You may be more vulnerable to malware or exploits that target system vulnerabilities protected by VBS.
• Can I disable VBS on Windows 11 Home? Disabling VBS typically requires Group Policy Editor, which is only available in Windows 11 Pro and Enterprise. For Home editions, editing the registry is the alternative.

This comprehensive guide should help you disable VBS in Windows 11 safely and effectively, whether for troubleshooting, performance gains, or other specific needs. Always proceed with caution and consider security implications carefully.
