kernel access

Kernel access refers to the level of control that software, particularly security tools, has over the core of the Windows operating system. Recent discussions on WindowsForum highlight Microsoft's reassessment of kernel access following the July 2024 CrowdStrike outage, which caused widespread Blue Screen of Death (BSOD) errors on 8.5 million devices. In response, Microsoft is moving security features away from the kernel to improve stability and prevent similar failures. The Windows Resiliency Initiative aims to enhance system resilience by limiting third-party kernel access. These changes affect how security vendors integrate with Windows, prioritizing safer, non-kernel environments for critical operations.
