Core Isolation is a virtualization-based security that is used to protect the core parts of your device. When this feature is enabled, the supported hardware will use virtualization to create a secure area of system memory isolating certain processes and software in the PC’s memory, so that your operating system can prevent malicious code.

Core Isolation Memory Integrity can be known as another security layer that can protect important operating system processes from being tampered with by anything running outside the secure area.

For its special and powerful functions, it requires your hardware and firmware to be virtualization-supported in the way Windows 10/11 can run applications in the container and make other parts of the system inaccessible.

In the start, this feature is only available on Enterprise editions of Windows 10 but now it has been developed among Windows 10/11 PCs that meet certain hardware and firmware requirements.

If you have noticed before, this feature is set off by default in Device security and the below feature shows you the name Memory integrity, known as Hypervisor-protected Code Integrity (HVCI).

Memory integrity is a subset of Core Isolation and when it is enabled, this service can run inside the hypervisor-protected container created by Core Isolation.

With such an excellent powerful feature, you may wonder why Microsoft set it off by default. According to the feedback of users, this feature can, more or less, dip down your PC performance and the compatibility issue with drivers becomes the biggest hamper.

This feature has high requirements for your device drivers and software. You must ensure your device drivers and Windows applications compatible with the Core Isolation feature.

Once one of your startup drivers has some issues with the feature, it will be disabled automatically so that the next operations can run well. That’s why you find it is off after the startup even though you have manually enabled it.

Besides, some people find that some devices or software will run into troubles after enabling Core Isolation. Under the circumstances, you can check for updates for this device or software.

And you need to notice that some applications can’t run with the Core Isolation feature, such as virtual machines or debuggers. These applications will ask exclusive access to the system’s virtualization hardware and that is forbidden in the Core Isolation-enabled situation.

This tutorial will apply for computers, laptops, desktops, and tablets running the Windows 10 and Windows 11 operating systems (Home, Professional, Enterprise, Education) from all supported hardware manufactures, like Dell, HP, Acer, Asus, Toshiba, Lenovo, Alienware, Razer, MSI, Huawei , Microsoft Surface, and Samsung.
