Useful resource for structures

VERGILIUS PROJECT

About
This project provides a collection of Microsoft Windows kernel structures, unions and enumerations. Most of them are not officially documented and cannot be found in Windows Driver Kit (WDK) headers. The target audience of this site is driver developers and kernel researches.

Where did we get the information?
Information about kernel structures, unions and enumerations is extracted from publicly available PDB files. We wrote a sophisticated parser that reconstructs C/C++ code from PDB files. So far it's the best known reconstructor as it can handle const/volatile modifiers, bit fields, function pointers, unions, arrays and anonymous types.

Wow super interesting but is it the end of the rabbit hole?
