11 Best Free System Information Tools

Reviews of the Best Free System Information Utilities

System information tools are software programs that gather all the important, but hard to come by, details about the hardware in your computer system. This sort of data is very helpful to someone helping you with a problem with your computer.

There are other great uses for these tools, too, like providing data on the type of RAM you have so you buy the right upgrade or replacement, creating a list of hardware when selling a computer, keeping tabs on the temperature of your important components, and lots more.

Speccy v1.32 in Windows 8
What We Like
  • Shows detailed information on lots of components

  • Lets you copy text out of the program

  • Results can be shared via the web and exported to a file

  • Works as a regular and a portable program

What We Don't Like
  • A report can't be made of specific sections of information

  • Infrequent updates

Piriform, creators of the popular CCleanerDefraggler, and Recuva programs, also produce Speccy, our favorite free system information tool. The program's layout is nicely designed to provide all the information you need without being overly cluttered.

A summary page gives you brief, but very helpful information on things like the operating system, memory, graphics, and storage devices. A more detailed look at each category is organized in their respective sections.

Our favorite feature is the ability to send system specs from the program to a public web page to easily share with others. Exporting to a file, as well as printing, are additional options, making saving a list of all your hardware details really easy.

This tool should work fine for all versions of Windows.

What We Like
  • Easy to read and use

  • Completely portable with a small download size

  • Supports making reports

  • Lets you copy text from the program

  • Includes features not found in other programs

What We Don't Like
  • Information on some components aren't included in reports

  • Isn't as detailed as similar tools

Free PC Audit includes all the features you'd expect to find in any system information utility, including the ability for a report to be saved as a simple text file.

For example, you can see information on all the hardware, like the motherboard, memory, and printers. In addition, it displays the Windows product key and ID, a list of installed software, and all the currently running processes, among many other things.

Free PC Audit is completely portable, making it perfect for a flash drive.

We tested it in Windows 10, 8, and 7, but it should also work fine in Windows 11 and older versions.

PC Wizard

PC Wizard 2014 v2.13 in Windows 7
What We Like
  • Lets you see a summary of everything in one section

  • Provides lots of detail

  • Supports copying and exporting results

What We Don't Like
  • Buttons aren't labeled, which can be confusing

  • It's often slow when scanning the computer

  • Setup tries to install another program

Another tool that shows detail on a huge variety of components is PC Wizard. It's easy to save a report detailing any or all parts of the program, and you can even copy out single lines of data to the clipboard.

Out of all the system information tools we've used, this one is certainly the most informative. It includes not only the basic and advanced information on internal and external hardware, but also useful operating system details.

PC Wizard can be installed on all versions of Windows, which includes Windows 11, 10, 8, 7, Vista, and XP.

Memory information in HWiNFO64 7.02
What We Like
  • Easy to use

  • Results are detailed

  • Lets you copy specific results

  • A one-page summary of all the details is available

  • Supports extensions

  • Works in Windows, as a DOS program, and in portable mode

  • Supports alarms

What We Don't Like
  • Missing information found in some similar programs

HWiNFO shows nearly the same details as these other free system information tools, like for the CPU, motherboard, monitor, audio, network, and other components.

A sensor status window is included to monitor the current and average speed/rate of the memory, hard drive, and CPU. HWiNFO can also run a benchmark against these areas.

Report files can be created for some or all of the system components, and you can also set up automatic reporting that sounds an alarm when a sensor exceeds a particular threshold.

Unfortunately, we found that this program doesn't include as much information as some of the other applications from this list. Although, the data it does display is still very helpful.

It runs on Windows 11, 10, 8, 7, and older ones. There's an installer, portable edition, and a download for DOS.

Belarc Advisor isn't as detailed as some of these other free system information tools. However, basic information on the operating system, processor, motherboard, memory, drives, bus adapters, display, group policies, and users are shown.

In addition to the above, a unique feature is the ability to list all the security updates Windows is missing. You can also view software licenses, installed hotfixes, program usage frequency, and version numbers for select Microsoft products.

Results of a scan open in a web browser and can be viewed on a single web page.

The program is quick to download and doesn't try to install additional programs during setup, which is always nice.

Both 32-bit and 64-bit versions of Windows 11, 10, 8, 7, Vista, and XP are supported.

ASTRA32 is another free system information tool that shows amazing detail on numerous devices and other parts of the system.

There are several categories to separate the information it gathers on hardware, like that of a motherboard, storage, and monitor information. 

A system summary section is perfect for seeing an overview of all the hardware and operating system details. Also, a dedicated section for live monitoring is included to show the temperature and current usage of various hardware components.

ASTRA32 works as a demo program, but it doesn't really mean much because it still provides lots of useful information.

It can be used on Windows 11, 10, 8, 7, Vista, XP, 2000, and Windows Server 2008 and 2003.

ESET SysInspector

ESET SysInspector
What We Like
  • Has lots of features that make it unique

  • Results are centered around security

  • It's portable

  • Can make reports about what the program finds

What We Don't Like
  • Isn't built to show as much info as similar tools

ESET SysInspector is dead simple to use because of its search utility and well-organized interface.

Results can be filtered to show information based on a risk level between one and nine. You can find basic information like available memory, system uptime, and the local time. More advanced details include things like environment variables, installed software, hotfixes, and an event log.

This program can also view a list of running processes and current network connections, active and disabled drivers, and a list of important registry entries and system files.

We like this tool because it is the only program in this list that is centered around providing detail regarding the security of the computer. However, it doesn't show exhaustive details like the higher rated system information tools in this list.

It should work in 32-bit and 64-bit versions of Windows 11, 10, 8, 7, Vista, XP, and 2000. Server operating systems are also supported, including Windows Home Server.

In addition to USB, hard drive, adapter, and basic OS details, SIV also includes a live sensor to show CPU and memory utilization.

The interface is a bit hard to look at—the details are too difficult to read. However, if you have the patience to look closely enough, you'll find all the information you'd expect.

It's designed for Windows 11, 10, 8, 7, Vista, XP, and 2000, plus older versions like Windows 98 and 95. It also works with Windows Server 2022 and some older versions.

  • Free for up to five devices

  • Export to HTML

  • Lots of detail

What We Don't Like
  • Takes a while to complete all the necessary scans

What makes PC-Doctor Toolbox stand out from the crowd is its remote viewer. After you install the program to your computer, you can log in from any web browser to check up on the stats.

There are several parts to this app. The Diagnostics tab lets you run system scans to check on the health of the motherboard, keyboard, hard drive, video card, etc. This is also where you can run BSOD troubleshooting if the app has detected a Blue Screen of Death. In here are also shortcuts to various Windows tools, like to configure network adapter settings or edit the Windows Firewall.

My Device is a summary page showing the current CPU usage, free space left on the hard drive, your local IP address, and a few other things. Selecting anything from that screen points you to the Information tab.

The Information tab is where all the system information is held. Lots of detail is included here about the OS, motherboard, hard drives, optical drives, audio, printers, memory, security, drivers, USB devices, and more. All of it can be packed neatly in an HTML file. There's also an area in this tab for listing detected app crashes.
