What is Windows kernel debugging?
Kernel mode debugging gives system engineers direct access to any part of the system, including the core Windows OS and device drivers. It is used to debug kernel programs and the kernel. It helps inspect the target program’s memory, control its execution, and manipulate its memory address space. For local kernel debugging, the debugger runs on the same system that is being debugged. And, if you want to establish a kernel-mode debugging session between a host computer and a target computer, then first you need to set up them and connect with a debug cable.
