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

I appreciate the summary page, which provides brief yet useful information on elements like the operating system, memory, graphics, and storage devices. Detailed information for each category is organized in their respective sections.

My favorite feature is the capability to send system specs to a public webpage for easy sharing. Additionally, you can export to a file or print, making it simple to save a list of all your hardware details.

This tool should work fine for all versions of Windows. I’ve used it in Windows 11 and Windows 10.

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.

You can view information on all the hardware, such as the motherboard, memory, and printers. It also shows the Windows product key and ID, a list of installed software, and all currently running processes, among other details.

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

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

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 this program doesn’t include as much information as some of the other applications from my list. Although, the data it does display is still very helpful, and support for extensions isn’t something I see in most system info apps.

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 other free system information tools. However, it provides basic information on the operating system, processor, motherboard, memory, drives, bus adapters, display, group policies, and users.

A unique feature I appreciate is the ability to list all missing Windows security updates. 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.

MiTeC System Information X is another free option, so that’s clearly a big plus. But I also like it because it’s portable, easy to use, and can create a summary report.

Among many other categories, you’ll find all the standard details like audio, network, and motherboard, information. More specific information can also be shown, such as drivers and processes.

The tabbed interface makes MiTeC System Information X easy to navigate, especially when viewing multiple reports simultaneously.

This program is compatible with Windows 10, 8, 7, Vista, XP, and 2000, as well as Windows Server 2019 through 2008. I used it without any issues on Windows 11.

EVEREST Home Edition is a portable free system information tool that scans very quickly and organizes everything it finds into several categories, including one for a summary page.

All the standard hardware details are included, like that of the motherboard, network, storage devices, and display

I appreciate that it allows the creation of favorites for instant access to any hardware component from the menu bar. It also generates an HTML report of everything or just specific items you select.

Unfortunately, this program is no longer being developed, which is probably why it doesn’t work perfectly in Windows 11. It also runs on Windows 10, 8, 7, Vista, and XP.

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.

Among all the system information tools I’ve used, this one is the most informative. It includes both basic and advanced information on internal and external hardware, along with useful operating system details.

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

ASTRA32 shows amazing detail on numerous devices and other parts of the system.

Information on various hardware, such as the motherboard, storage, and monitor, is organized into several categories. A system summary section provides an overview of all hardware and operating system details. Additionally, a dedicated live monitoring section shows 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. That said, I’ve placed it in this position of the list to encourage you to first try the other, better choices listed above.

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

ESET SysInspector is dead simple to use because of its search utility and well-organized interface. If some of these other programs look too difficult to work with, I recommend giving this one a try just for its simplified UI.

Results can be filtered to show information based on a risk level from one to nine. You can find basic information such as available memory, system uptime, and local time. More advanced details include 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.

I like this tool because it’s the only program in this list that’s 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.

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.

Although the interface is somewhat difficult to view due to crowded details, all expected information is available if examined closely.

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.
