# Process Hacker / System Informer: Introduction and Configuration

**System Informer** is the actively developed successor to the popular (but now discontinued) Process Hacker 2. It is a free, open-source, and exceptionally powerful multi-purpose system utility that is **essential** for effective manual screensharing. While it offers extensive system monitoring and debugging capabilities, its primary relevance for screensharing lies in its ability to **deeply inspect running processes, services, network connections, and, crucially, their associated memory contents** for signs of unauthorized software or manipulation.
