Device Drivers

This documentation is for user-mode applications that want to use ETW for event tracing. This documentation is not for device drivers that run in kernel-mode. For those writing device drivers and kernel-mode applications that want to use ETW as a low-impact debugger to troubleshoot timing-related problems, see Event Tracing for Windows, WPP Software Tracing, and WMI Event Tracing in the Windows Driver Kit (WDK) for information on instrumenting your driver.
