Updated January 02, 2019 48 48 people found this article helpful 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. I've only included free system information tools in this list. Please let me know if one of these programs is no longer freeware and is now charging, and I'll remove it. 01 of 11 Speccy Speccy v1.32.740. 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 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. Speccy Review & Free Download 02 of 11 PC Wizard 2015 PC Wizard. 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 Doesn't work in Windows 10 Buttons aren't labeled, which can be confusing It's often slow when scanning the computer Setup tries to install another program Another free system information tool that shows detail on a huge variety of components is PC Wizard 2015. 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 I've used, PC Wizard 2015 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 2015 can be installed on Windows 8, 7, Vista, and XP. It doesn't work on Windows 10. PC Wizard 2015 Review & Free Download 03 of 11 System Information for Windows (SIW) SIW. © Gabriel Topala What We Like Very easy to use and read Doesn't need to be installed (it's portable) Supports making a report and copying text from the application Takes up very little disk space Shows information for things most similar programs don't reveal What We Don't Like Doesn't run on Windows 10 or Windows 8 Can't make detailed reports 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. SIW is so full of detail that it oftentimes takes awhile for the information to populate when you first open the program. Only Windows 7, Vista, XP, and 2000 users can use SIW, as it's not compatible with Windows 10 or Windows 8. System Information for Windows (SIW) Review & Free Download 04 of 11 ASTRA32 ASTRA32. © Sysinfo Lab What We Like Info from every category is summarized on one page Reveals detailed information on computer hardware It can be used without installation as a portable program What We Don't Like Doesn't run in Windows 10 Functions as a demo program Some information gets truncated Doesn't let you copy text out of the program Shows ads to buy the full program 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. 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. ASTRA32 Review & Free Download 05 of 11 HWiNFO HWiNFO64 v6.00. 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, 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. HWiNFO Review & Free Download 06 of 11 Belarc Advisor Belarc Advisor 8.5c. What We Like Runs quickly Shows unique information not found in other programs Includes basic information on lots of hardware components The setup file is really small Software information is shown, too What We Don't Like Doesn't have a summary page You have to install the program to your computer 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 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. Belarc Advisor Review & Free Download 07 of 11 Free PC Audit Free PC Audit.

What We Like Lets you favorite components for easier access Condenses everything into several categories It's a portable program Reports can be made of some or all of the data What We Don't Like The program no longer gets updated It's not as detailed as other similar tool EVEREST Home Edition is a portable free system information tool that scans very quickly and organizes everything it finds into nine categories, including one for a summary page. All the standard hardware details are included, like that of the motherboard, network, storage devices, and display, with the ability to create an HTML report of everything. You can create favorites in EVEREST Home Edition to have instant access to any hardware component from the menu bar. Unfortunately, EVEREST Home Edition is no longer being developed. This means if it's still not being developed in the future, the new hardware devices that are released will likely not be recognized by the program. Windows 10, 8, 7, Vista, and XP users can install EVEREST Home Edition. EVEREST Home Edition Review & Free Download 10 of 11 System Information Viewer (SIV) System Information Viewer. © Ray Hinchliffe What We Like Shows detailed information There's a summary page Monitor system resources Reports can be made for all the info or just some of it No need for installation (it's portable) What We Don't Like Results are hard to read The interface is cluttered Searching doesn't work well SIV is another free system information tool for Windows that runs as a portable program (i.e., no need to install). In addition to USB, hard drive, adapter, and basic OS details, SIV also includes a live sensor to show CPU and memory utilization. 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. System Information Viewer (SIV) Review & Free Download 11 of 11 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. 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. 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. ESET SysInspector Review & Free Download Continue Reading
