How to Enable Core Isolation Memory Integrity in Windows 11
Core Isolation Memory Integrity in Windows 11 blocks malicious low-level attacks by creating a secure, isolated space in your computer’s memory. This built-in security tool relies on Virtualization-based Security (VBS) and Hypervisor-protected Code Integrity (HVCI) to stop unapproved software and bad drivers from running on your system.
Windows 11 checks every driver before it loads to make sure only trusted code runs on your PC. You need a processor with hardware virtualization turned on in your BIOS settings to use this feature.
Open Windows Security, navigate to Device security, then Core isolation details, and toggle the Memory integrity switch to On. This feature protects your system kernel by preventing malicious drivers from running.
How to enable or disable Core Isolation Memory Integrity
Core Isolation Memory Integrity stops harmful software from taking over your PC by blocking untrusted system drivers. You can turn Core Isolation Memory Integrity on or off by opening Windows Security, going to Device security, and choosing Core isolation details. If an incompatible driver blocks the switch, Windows will list the problematic file so you can remove or update it before trying again.
- In the search box on your taskbar , type Windows Security and select it from the list.
open windows security app - Inside the Windows Security window, click on Device security.
- On the next page, click the link labeled Core isolation details.

Troubleshooting Incompatible Drivers
Troubleshooting incompatible drivers is necessary when Core Isolation Memory Integrity refuses to turn on because of outdated hardware software. Windows prevents the security feature from starting if an old driver could allow malware access to your system memory. You need to check the Core isolation screen to see which file is causing the block, then visit the hardware manufacturer’s website to download an updated version.
To fix this, you should visit your computer manufacturer’s website. Look for updated drivers for your hardware. If you cannot find an update, you may need to uninstall the device or the software associated with that driver. You can often find the specific file path, such as 📁C:\
Comparison of Windows Security Features
| Feature | Purpose |
|---|---|
| Core Isolation | Uses virtualization to isolate core processes. |
| Secure Boot | Ensures only trusted firmware boots the PC. |
| Kernel-mode Hardware-enforced Stack Protection | Protects against memory-based attacks. |
Summary
Core Isolation Memory Integrity is a security feature that uses virtualization to protect your computer’s core system from harmful software.Why is Memory Integrity greyed out?
Memory Integrity might be greyed out if your computer’s hardware doesn’t support virtualization, or if this setting is turned off in your computer’s BIOS.
