BugChecker
BugChecker is a single-host kernel debugger for the Microsoft Windows 2000 and XP operating systems. "Single-host" means that the debugger and the debuggee (in this case the whole system, comprehensive of the kernel, hal, device drivers and user applications) can be debugged on a single machine, without the need of a second computer running the debugger application. "Kernel debugger", as the name suggests, is a program that allows to "trace" inside the system kernel, setting breakpoints and the like as you would do when debugging a normal user application.
