System Informer (formerly known as Process Hacker) is the world's most powerful, free and open-source system diagnostics, process management, kernel monitoring, and memory inspection utility for Microsoft Windows. Engineered by the System Informer Team, System Informer provides systems engineers, cybersecurity analysts, reverse engineers, software developers, and Windows power users with an unparalleled real-time view into running processes, active services, open network sockets, loaded DLL modules, kernel drivers, system performance statistics, and hardware interrupts.

Far exceeding the capabilities of the default Windows Task Manager, System Informer allows users to safely terminate stubborn hung tasks, inspect memory spaces, edit security access tokens, monitor disk I/O rates per process, and detect malware hooks using dedicated kernel-mode drivers with zero advertising and zero telemetry.

## 🌟 Core Architecture & Engineering Highlights

System Informer is written in high-performance native C and operates with an optional signed kernel-mode driver (`kprocesshacker.sys`) that bypasses user-mode obfuscation.

### Key Architectural Strengths:
- **Hierarchical Process Tree Visualization**: Displays all running Windows processes in a color-coded parent-child hierarchy, instantly revealing unauthorized background child processes and sub-tasks.
- **Kernel-Mode Driver Architecture**: The signed kernel driver provides low-level process termination, memory inspection, and security token privileges even for protected processes.
- **Real-Time Network Socket Monitoring**: View all active TCP connections, listening UDP ports, remote IP addresses, bandwidth transfer rates, and geographical geolocation per process.
- **Deep Memory & Handle Inspection**: Search, inspect, and dump process memory heaps, edit string tables, and close locked file handles without rebooting your PC.
- **High-Precision Performance Graphs**: Real-time graphs for CPU multi-core utilization, GPU 3D engine usage, dedicated/shared VRAM, disk read/write throughput, and kernel commit charges.

## ⚙️ Key Capabilities & Diagnostics Tools

System Informer equips system administrators and power users with comprehensive forensic tools.

### 1. Advanced Task & Process Management
- **Forceful Process Termination**: Terminate unkillable malware processes, hung background tasks, and locked services with kernel-level termination hooks.
- **Process Suspension & Throttling**: Pause CPU-heavy games or render tasks temporarily to free up resources without closing the application.

### 2. Security Token & Privilege Auditing
- **Access Token Editing**: Inspect, enable, or disable Windows security privileges (`SeDebugPrivilege`, `SeShutdownPrivilege`) and view User Account Control (UAC) virtualization status.
- **Digital Signature Verification**: Instantly verify Authenticode digital signatures on running processes and loaded DLLs to detect unsigned malicious binaries.

### 3. File Lock & Handle Search
- **Unlock Locked Files**: Search for open file handles (`Ctrl + F`) to find out which application is locking a file and unlock it immediately with one click.
