System Informer

System Informer is a free, multipurpose software tool for monitoring computer activity, debugging software, and detecting malware. It provides detailed, real-time views of system resources and processes, helping users identify resource-intensive programs, investigate runaway processes, and understand system performance. Graphs and statistics can be explored over time, including information about processes that have since stopped running.

The tool also helps users find processes that are accessing a particular file by searching for handles or DLLs, and it shows programs with active network connections. Additional features provide detailed process and system activity, live disk access and usage data, network usage information, GPU usage by process, and service and driver management. For software troubleshooting, System Informer can display detailed stack traces with kernel-mode, WOW64, and .NET support. Users can add columns to see more activity data and choose light or dark themes, with optional modern icons. System Informer is available to download, and users can access its project resources, report bugs, ask questions, or connect with the community through its listed channels.
