Freeware Shorts: System Explorer (Everything About Your Computer)

System Explorer

System Explorer (Version: 3.6.2 as of this post) bills itself as a system management tool and an explorer of system internals. It is more than just a system profile builder. System Explorer provides lots of, almost too much, information about many aspects of the system or computer in a tabbed interface. Some tabs are open and visible when starting the program, others can be opened in the Firefox new tab style by clicking the + button to the top right and choosing from the available sections. Most sections or tabs have additional capabilities via a right click. Examples include terminating processes, copying file paths to the clipboard, virus checking a file online on and many more.

System Explorer also has a status bar at the bottom with CPU, RAM, swap file and other usage information. A similar graphical overview is also available via the color of its tray icon or hovering over the icon itself.

Tasks is like the windows task manager’s Applications tab, it provides a list of open programs. Processes list all running processes with process id (PID), CPU time, memory usage, ‘sub’ processes, parameters the process may be running with, online security check (click the security check icon and any details available in the system explorer database will be shown online) and more. Also like many other sections, System Explorer has a search feature near the top right.

Modules lists the dll files the running programs are using, like some other sections this can be filtered to not show Windows’ own. Performance (see image) shows graphs for overall processor or CPU, page fault, swap, network connection, kernel and physical memory usage and lots more. Services list all services running with their driver type, name and startup type or mode (automatic, manual or disabled). Drivers lists all drivers running on the system including name, startup type and location/path. Windows is much like Tasks but has a list of all open windows, so if several instances of one program are open you see them here. Autoruns has a list of all processes or programs that run automatically on startup. Uninstaller has the shortcuts to uninstall programs. History is like an event viewer of sorts in that it contains a list of all recent actions, for example “New TCP/IP PID=3292 “Palemoon.exe””. Snapshot takes snapshots of the file system and registry and saves it for future comparison.

System Explorer

There are additional sections that list Users, Security Info with basic information on anti virus and Windows firewall states and Additional Info with lots of information on the system like Windows serial number, computer name, system folders, system date, audio and video codecs, fonts, file types and lots more.

It is really necessary to explore the program or have a look at the online help to really discover all its features. System Explorer is free for personal use and runs on Windows XP and newer versions.


  1. System Explorer has been my favourite task manager for years being (at least for me) the most powerful, feature-rich and complete tool among all other similar free applications (Auslogics Task Manager, Process Explorer, Process Hacker, etc.) but some time ago the developer began to include adware modules (Driver Scan, Security Scan, etc.) in both portable and installer versions so I keep an older release and never update it any more.
