Process Explorer is a free advanced task manager from Microsoft's Sysinternals suite, originally created by Mark Russinovich. It shows what standard Windows Task Manager doesn't: a full process tree with parent-child relationships, every file, registry key and DLL a process has open, and which company signed each running executable. It requires no installation and runs directly as a portable executable.
Why Process Explorer Goes Further Than Task Manager
Windows Task Manager tells you a process is running and roughly how much CPU or memory it's using, but not much else. Process Explorer adds the detail power users and IT professionals actually need: a searchable index of every open handle and loaded DLL, a live process tree showing exactly what launched what, and the ability to verify a running executable's digital signature before deciding whether to trust it.
Process Explorer Features
- Process Tree View — displays running processes with their parent-child launch relationships
- Handle and DLL Search — find which process has a specific file, registry key or DLL open
- Digital Signature Verification — checks whether a running executable's publisher signature is valid
- VirusTotal Integration — optionally submits a running process's image hash to VirusTotal for a reputation check
- CPU, GPU and Memory Graphs — live performance graphs for the system and individual processes
- Find Window's Process — drag a crosshair onto any open window to instantly identify its owning process
- Suspend and Kill Process Trees — pause or terminate a process along with its child processes
- No Installation Required — runs as a single portable executable

Avoid third-party "download manager" sites offering Process Explorer. They commonly wrap the genuine installer in their own bundler, which is how adware and browser hijackers get onto a machine that the user believed was clean.
