Windows Software Trace Preprocessor (WPP preprocessor)

The Windows software trace preprocessor (abbreviated WPP; the preprocessor and related support tools are known as WPP Software Tracing) is a preprocessor that simplifies the use of WMI event tracing to implement efficient software tracing in drivers and applications that target Windows 2000 and later operating systems.

WPP was created by Microsoft and is included in the Windows DDK. Although WPP is wide in its applicability, it is not included in the Windows SDK, and therefore is primarily used for drivers and driver support software produced by software vendors that purchase the Windows DDK
