About this tag
Core isolation is a Windows security feature introduced with the Windows 10 April 2018 Update and built into Windows 11, leveraging virtualization-based security to isolate kernel-level processes. Its Memory integrity component, also known as Hypervisor-Protected Code Integrity (HVCI), prevents malicious or unsigned code from running in the Windows kernel, protecting against rootkits and vulnerable drivers. Enabling core isolation can fail if incompatible drivers are detected, requiring troubleshooting to resolve blocks. While it strengthens system defenses, some users report performance impacts, particularly in gaming scenarios. Discussions on WindowsForum.com cover enabling the feature, fixing driver compatibility issues, and balancing security with performance, especially on systems like AMD Ryzen processors.
