Capture ETW events with C++ (Part 1)

ETW is the backbone of Windows telemetry and most developers never touch it directly. Here's how to consume real-time ETW events in C++, from zero. In this video I walk through the full pipeline: creating a trace session, enabling a provider, setting up a real-time consumer, and receiving event callbacks all in plain Win32 C++. What you'll learn: • How to structure and allocate EVENT_TRACE_PROPERTIES correctly • How to call StartTrace, EnableTraceEx2, OpenTrace, and ProcessTrace • How to implement an event record callback and extract header data (PID, TID, timestamp) • How to handle the "session already exists" error gracefully • Why admin privileges are required and when they're not Full write-up with code on the TrainSec free knowledge library: https://trainsec.net/library/windows-...
