Replacements
Listings that take over the same core job as Process Explorer.
System Informer
An open-source Process Explorer alternative that monitors resources, debugs software and helps detect malware, with no installation needed.
System Informer is open source under MIT and adds service control and detailed kernel-mode stack traces, but needs Windows 10 or later and its driver may be flagged.
Sysinternals Suite
Microsoft's bundle of Sysinternals troubleshooting and diagnostic utilities for Windows in a single download.
Sysinternals Suite bundles dozens of Microsoft diagnostic tools in one roughly 192 MB download with ARM64 builds, for those wanting the wider toolkit alongside process inspection.
NeoHtop
Inspect running processes in a desktop system monitor.
NeoHtop is an MIT-licensed desktop process monitor for Windows, macOS and Linux offering CPU and memory views with process search and filtering, rather than handle and DLL inspection.
Also worth comparing
These listings name Process Explorer as their own alternative, so the relationship runs both ways.
Task Manager DeLuxe
A portable Windows task manager replacement with detailed process, service, network and performance monitoring.
Process Explorer is Microsoft's portable Windows process viewer with parent-child trees, open handles and loaded DLLs, but lacks per-process network traffic and autostart viewing.
