Process Explorer for Windows download

Quick summary

Process Explorer provides a detailed view of everything running on your PC, showing processes, their properties, and files in use. It’s presented as a hierarchical tree inside a split window so you can quickly drill down into any item and inspect its details.

The interface combines a tree view with a dual-pane display: the top pane shows active processes in a parent/child hierarchy, and the lower pane reveals in-depth data for whatever process you select. Use the tree to trace which programs launched which services and subprocesses.

Control actions you can perform

Inspect a process’s full properties, including its memory use and other resource counters.
Force an application to exit (terminate individual processes).
Alter a running process’s scheduling priority to change how the OS favors it.

Performance and usage indicators

Memory and disk footprint measurements, along with other process-specific resource counters.
Live CPU usage and graphs that summarize overall system load.
Input/output statistics showing current read/write activity.

Managing libraries and mapped files

Process Explorer enumerates loaded DLLs and memory-mapped files for each process, making it useful when tracking down module-related faults. You can apply filters to narrow the view to only DLLs or to include memory-mapped resources, which helps isolate problematic components.

Limitations and usability notes

The program’s built-in help is not functional, so there’s no integrated guidance if you run into questions. Because of that, Process Explorer works best for users who are comfortable exploring tools without step-by-step help or who can consult external documentation.
