WinObjEx64 is a Windows desktop application for browsing and analyzing the Windows NT Object Manager namespace. It provides a graphical tree/list view of kernel objects (directories, processes, threads, tokens, sections, ALPC ports, etc.) and exposes detailed properties, security descriptors, and internal kernel structures through property sheets and extra dialogs. The tool goes beyond standard object managers by reading kernel memory via a custom driver, allowing introspection of undocumented structures such as callback arrays, system service dispatch tables, control areas, and NDIS protocol blocks. It also includes a plugin system (via versioned DLLs) for extending functionality, with built-in plugins for API set schema viewing, NDIS protocol enumeration, and section object analysis. Architecturally, WinObjEx64 is a single-process native Win32 GUI application built with the Windows API. Its core modules include object enumeration (list.c), property page display (props/), kernel memory reading abstraction (drivers/ with interchangeable backends like KD, WinIo, or the custom kldbgdrv), and a worker-thread-based extras dialog system for complex system analysis (extras/). Key entry points are main.c (application lifecycle), list.c (object tree navigation), and plugmngr.c (plugin loading). External dependencies are limited to the Windows SDK, DbgHelp for symbol resolution, and optionally a signed kernel driver for advanced features. Data flows primarily involve querying the NT Object Manager via system calls (NtQueryObject, NtOpenDirectoryObject, etc.) and reading kernel memory through the driver (kdReadSystemMemory). Results are displayed in custom controls (TreeList, property sheets) with sorting, filtering, and CSV export. The plugin system allows third-party code to add new object types, dialogs, or analysis views by implementing a simple ABI with versioned structures and callbacks.
