11 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 system information 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.

Note: I've only included free system information tools in this list. Please let me know if one of these programs is now charging and I'll remove it.

Piriform, creators of the popular CCleaner, Defraggler, and Recuva programs, also produce Speccy, my favorite free system information tool.

Speccy'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.

My favorite feature is the ability to send system specs from Speccy to a public webpage 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.

Speccy works with all versions of Windows from Windows 10 through Windows XP. More »

Another free system information tool that shows detail on a huge variety of components is PC Wizard 2014.

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.

PC Wizard 2014 Review & Free Download

SIW is a portable and completely free system information tool that shows detail on tons of different areas in Windows.

In addition to regular information like that about standard hardware, SIW also reveals detail regarding installed applications, among many other areas of Windows.

Everything SIW finds is separated into three easy to read sections, called Software, Hardware, and Network, with even more specific subcategories.

A summary report that contains basic hardware and software information can be exported to an HTML file.

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 Review & Free Download

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

ASTRA32 can be used on Windows 8, 7, Vista, XP, 2000, and Windows Server 2008 and 2003. I tested it in Windows 10 but was unable to get it working. More »

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.

HWiNFO Review & Free Download

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

HWiNFO runs on Windows 10 through Windows XP. More »

Belarc Advisor 8.5c.

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 in Belarc Advisor 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.

Belarc Advisor Review & Free Download

Belarc Advisor 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 10, 8, 7, Vista, and XP are supported. More »

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

System Information Viewer (SIV) Review & Free Download

I think 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.

SIV is designed for Windows 10 through Windows 2000, plus older versions like Windows 98 and 95. It also works with Windows Server 2012, 2008, and 2003. More »

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 1 and 9. 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.

ESET SysInspector 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.

ESET SysInspector Review & Free Download

I like ESET SysInspector 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.

ESET SysInspector can be used in 32-bit and 64-bit versions of Windows 10, 8, 7, Vista, XP, and 2000. Server operating systems are also supported, including Windows Home Server and Windows Server 2012/2008/2003. More »
