Part 1: What Is the Kernel Security Check Failure on Blue Screen?

The Kernel Security Check Failure, also known as the Blue Screen of Death (BSOD), is an error message displayed on a blue screen in Windows 11 as well as Windows 10, meaning that the core component of the operating system - Kernel - is corrupted and leading to a critical related system issue.

When the Kernel detects a violation in the system's security protocols or encounters a problem with a driver or hardware component, it triggers a mechanism called a “bug check” or “stop error”, resulting in BSOD with the Kernel Security Check Failure error message. The purpose of it is to prevent further damage to the system and to ensure the stability and security of the computer.

The causes of the "Kernel Security Check Failure" can vary and may include incompatible or outdated drivers, faulty hardware, memory problems, system file corruption, or malware infections.
