Best Free System Information Utility

 
In a Hurry?
  Go straight to the Quick Selection Guide
Introduction
The freeware utility AIDA32 was for a long time the best system information / inventorying tool ever, regardless of price.  It documented just about every aspect of your hardware and software configuration as well as checking networks and providing memory benchmarks. However the developer announced in March 2004 that the free product had been frozen and development work shifted to another organization where AIDA32 was re-launched as a commercial product called Everest. Then in 2010 Everest was aquired by FinalWire who shut down Everest and released AIDA64.
Discussion

You can however still find the old AIDA32 and the non-discontinued free version of Everest called Everest Home. The old AIDA32 works better across networks while Everest Home covers more modern hardware than AIDA32.

If you only need to inventory a single PC then you should also check out Belarc Advisor. It's free for non commercial use and while not quite as thorough as AIDA32, it has the advantage of being actively developed.

My current favorite for home use is the SIW utility written by Gabriel Topala. It "displays detailed specs for motherboard, BIOS, CPU, devices, memory, video, disk drives, ports, printers, operating system, installed programs, processes, services, serial numbers (CD keys), users, open files, system uptime, network, network shares, as well as real-time monitors for CPU, memory, page file usage and network traffic. It also displays currently active network connections, passwords hidden behind asterisks, installed codecs, and more." That's impressive enough for a freebie but my favorite feature is SIW does not need installing; all you need to do is run the executable. This means one less installed program on your PC as well the fact that you can run the program directly from a USB flash drive.

PC Wizard is a system information utility that is strong in workstation description and benchmarking. It's a well implemented program with a nice multi-panel display with different analysis functions easily selectable using sidebar buttons. Overall it provides a little less system information that SIW but the benchmarking feature makes up for it. Benchmarks can be run on individual parameters such as processor performance, memory and cache speed, video performance and hard drive speed or can be run be for all functions with the single press of a button. In the latter case an overall numeric system performance index is also calculated. Overall PC Wizard is an impressive system utility well suited to those who want to get a better understanding of their PC's configuration and performance. The fact that it is regularly updated adds further to its appeal.

Probably the most advanced system information viewer. Warning: For power users only.

Maybe this is a new development but... SIW is not freeware. Click on download link and you're taken to a page of commercial products, only.

by wreckage on 12. December 2012 - 21:57  (103559)

Unfortunately, the SIW freeware version is no longer supported. Here is what is written on the vendor's web site:
"Note: SIW Home Edition is discontinued."

in tab "download" primary you have payed versions, but below you will find "Download Old SIW 2011 (build 1029) - Home Edition", and a little bit lower: "Old SIW 2011 Home Edition (with OpenCandy) - Download"

Thank you. :) OpenCandy information page here:

Beware SIW, the freeware version. There is no longer a freeware version available without OpenCandy. Additionally, there is no longer a "portable version".

OpenCandy is described in Wikipedia as "an advertising software module" here ...

http://en.wikipedia.org/wiki/OpenCandy

My security software, Microsoft Security Essentials, believes it to be malware of some sort and requests that I "remove" it. I have and am now looking for something to replace it.

I guess Gabriel Tapola decided that the money OpenCandy offered him to add it to his freeware version was ample enough for him to compromise his formerly fine software.

by mrinmoyjk on 26. May 2012 - 16:09  (94002)

The new download link is : http://www.gtopala.com/siw-download.php
and download the "Home Edition".

by MidnightCowboy on 26. May 2012 - 18:10  (94009)

Beware! The home edition is bundled with OpenCandy.

The SIW Utility is good. Too bad that they've started bundling unwanted stuff:(. Just tried their portable app edition and it's fine.

SIW now includes OpenCandy in it's installer. Go for the portable version available at their website

by sys-eng (not verified) on 28. October 2011 - 20:02  (82329)

My primary use of these inventory utilities is to collect software licenses in case I have to reinstall a program. Most users do not save their license keys and just lose the programs if their hard drive dies or their system burns, etc..

My experience with all of these products is they catch about half of the licenses at best. I just tried the SIW portable again today, and it missed significant programs such as Adobe Photoshop Elements. If one of these programs did what they claim, I would pay $30 for it.

by jason on 28. October 2011 - 22:40  (82336)

(even though this article was aimed primarily at programs that obtain hardware specs - you raise a good point).

The problem lies not with the apps (like SIW or Belarc) but with the apps you are trying to capture the serial / keys for. There is no common location or method for apps to record and store their serials. In fact, many apps go out of their way to obfuscate the keys and serials to reduce the likelihood of piracy from users of the PC from being able to copy the keys and register the software on their own PCs.

Considering there is no common location, storage format, or standards for storing registration keys (many apps don't even store the original registration key, but some form of hash) - the task of developing an app to locate and decode the original installation keys for "major" programs starts to look not worth the effort when you consider the alternative.

The alternative? When purchasing new software and before installing the software - keep an updated software register. This can be as complex as a dedicated database application or something as simple as a spreadsheet or even a text file created in notepad, with the name of the application, the application website url and the install key information. You will usually get all this information emailed to you when you purchase software (online). Just put it all together in a single location / database / file.

When you have to rebuild or reinstall apps for whatever reason - a software register will make everything so much easier, and the best part is that your software register works with EVERY application and it is free (of course - just make sure you back it up).

I haven't had a chance to try SIW (which I will). It sounds as if it's portable. But also check out Speccy by Piriform (makers of CCleaner and Recova). I would like to see how it ranks with the already mentioned competition. See link for more information:

http://www.piriform.com/speccy

by Jonas Konski on 11. November 2012 - 11:25  (102153)

Thanks!
I was trying to find out what graphic card I have on this Windows 8 machine and the other programs like SIW didn't work on Win8 and others just crashed or froze.

Speccy did the job! Should be listed!

by Caramac (not verified) on 27. December 2011 - 18:39  (86084)

Latest Speccy is not running properly. Version 1.13, 1.14 crash.
My W. XP-SP3 Pro Dell runs Speccy 1.10 fine, but my XP-SP3 Home Dell gives a C++ error. (2) MS Visual C++ 2005 versions installed may be why.

ALL versions available to download at
http://www.filehippo.com/download_speccy (even v.1.0 betas)

What I like is the main page and subsections have just what I was looking for. GPU temp for example.

SIW spits out every conceivable piece of information in organized fashion, great for troubleshooting.

It would be a shame if Gabriel decides to discontinue the Freeware version - as so many home users find his program to be so useful.

In the meantime - if you are looking for this (while it lasts?):

Just saw that free version of SIW is back on the site, and even has an update.

by Anupam on 2. October 2011 - 17:50  (80761)

It now comes with OpenCandy... so beware while installation. :(

by Anupam on 25. September 2011 - 6:56  (80290)

That seems to be true sadly :( .. the site layout has changed, and on the download page, the freeware version is no longer to be seen. I think that it was the best program out there in terms of system information. That's quite sad.

Another tool is Fresh Diagnose, one of a range of free utilities bearing the Fresh name. Their product description reads "Fresh Diagnose is a utility designed to analyze and benchmark your computer system. It detects many kinds of hardware, such as CPU or hard drive performance, video or motherboard information and much more. This software is 100% free, no ads, no spyware." Find it at http://www.freshdevices.com/

SIW shows up as a false positive in several anti virus programs including Symantec and others...

Big downer for me. Symantec deleted my SIW.exe without even a warning...

SIW 2011 is no longer free, so it does not really matter. ;)

SIW 2011 is Gabriel's commercial/professional version and is not free nor has been for a long time.

SIW remains free for personal use. It really is the best although Speccy is coming up fast from behind.

SIW 2010 (outdated) is free, SIW 2011 is not, I moved to PCWizard anyway.

Yes it is, you just need to look further down the page. I have just downloaded and run it.

SIW Standalone Freeware Version has been discontinued and before you say it, yes there is home edition, which is older version to force people to buy new one.
