Process Hacker is a free, open-source utility for monitoring system processes and services running on both 32-bit and 64-bit Windows operating systems. It serves as a replacement or supplement to the Windows Task Manager.
The list of all processes can be displayed in various formats, including simple or tree view, with options to show hidden processes and more. A similar list for services allows for quick management (stopping, starting, deleting). Specific processes related to a single application are grouped together and highlighted with a distinct color. Monitoring and control also extend to dynamic link libraries (DLLs) and the detection and complete removal of rootkits.
Key features include:
- Termination of any processes (including antivirus and firewall programs, thanks to the application’s kernel-mode driver);
- Viewing process statistics;
- Displaying performance graphs;
- Full execution history of processes;
- Customizable tree view with color coding;
- Viewing memory used by a specific process;
- Debugging executable programs;
- Reading and editing security descriptors for processes, threads, and handles;
- Detecting hidden processes and terminating them promptly;
- Simple unloading of DLLs;
- Viewing and closing network connections;
- Detaching from debuggers.
As of June 2022, the program has been developed by a new team and has been rebranded as System Informer for Windows.
System Informer, commonly known as Process Hacker, is a powerful tool used primarily by IT professionals, system administrators, and advanced users to monitor and manage system processes and resources. This open-source utility provides deep insights into running processes, services, and system performance, allowing users to identify issues that may affect system stability or security.
Moreover, security analysts leverage System Informer to identify malicious processes that may be running undetected on a system. By providing real-time monitoring and the ability to manipulate processes, it aids in the detection of potential threats and enhances overall system security. In essence, System Informer is a versatile tool that empowers users to optimize performance and maintain the integrity of their systems.
IT professionals utilize System Informer for troubleshooting purposes, enabling them to detect resource-hungry applications, analyze memory usage, and terminate unresponsive processes. Its advanced features, such as the ability to view detailed information about each process, including handles and threads, make it an invaluable resource for diagnosing complex problems.

Use Ctrl+F to search for a handle or DLL. If all else fails, you can right-click on an entry and close the handle linked to the file. However, this should only be considered as a last resort, as it may result in data loss or corruption.
