Process Hacker Overview
Process Hacker is a free, open-source advanced process viewer and system-monitoring tool for Windows, often described as a powerful replacement for Task Manager. It shows detailed, color-coded information about running processes, their resource usage, threads, handles, loaded modules, and network connections, and lets you inspect or terminate processes that Task Manager cannot. It is widely used for troubleshooting, malware analysis, and understanding exactly what a system is doing, with the ability to dig into a process's memory and properties. Note that the project's active development has continued under the name System Informer. As a single complete installer, Process Hacker finishes setup on a machine that has no connection. It can also reveal which process is using a file or folder, which is handy when Windows blocks a delete or rename with a 'file in use' error.
