BugChecker is a SoftICE-like kernel and user-mode debugger for Windows (XP through 11, x86 and x64) that runs entirely on the machine being debugged, without requiring a second host. It works by intercepting the kernel's KD API (KdSendPacket/KdReceivePacket) via a KDCOM.DLL replacement, presenting itself as an external kernel debugger while displaying output on a linear framebuffer and accepting input from a PS/2 keyboard.

Use cases

• debug windows kernel without a second machine
• softice-like debugger for windows 11
• single-machine kernel debugging on windows
• set breakpoints and inspect memory in kernel mode
• debug wow64 processes on x64 windows
• disable patchguard while kernel debugging
• step through kernel code with js expressions

When to choose

• you need kernel debugging on a single Windows machine without a host debugger or serial cable
• you want a SoftICE-style full-screen debugger experience on modern Windows
• you need to support debugging from Windows XP through Windows 11, x86 and x64
• you want to script debugger commands with JavaScript expressions

When to avoid

• you need a debugger with a modern GUI or IDE integration
• your machine lacks a PS/2 keyboard (built-in or external) and a linear framebuffer
• you require official vendor support or long-term stability guarantees
• you need to debug non-Windows operating systems
