!!! warning Core Isolation Page Missing
You must have Virtulization enabled to use Core Isolation features. If you can't find the Core Isolation page in Windows Security, you may need to enable Virtualization in your BIOS/UEFI settings.

[Core isolation](https://support.microsoft.com/en-us/windows/core-isolation-e30ed737-17d8-42f3-a2a9-87521df09b78) is a security feature of Windows that protects essential core processes of Windows from malicious software by isolating them in memory. It mostly does this by running those core processes in a virtualized environment.

For Windows 11 users on supported hardware, core isolation features are enabled by default. Although effective, it comes at a **significant performance cost**. We generally recommend disabling core isolation features as the [performance hit](https://www.tomshardware.com/news/windows-11-gaming-benchmarks-performance-vbs-hvci-security) outweighs the security benefits for many users. However, remember that core isolation might not affect some applications and games more than others.
