When it comes to debugging on Windows, there are many existing tools (OllyDbg, Immunity Debugger, x64dbg) but none come close to the functionalities offered by WinDbg. Often seen as harder tool, we'll use this workshop to focus on the latest version of WinDbg (previously known as WinDbgX or WinDbg Preview) to share some (lesser known) insights and useful techniques, for both user and kernel mode debugging during this hands-on workshop.
