Lift The Hood On Your PC – Take a Peek With These 5 Free System Information Utilities

imageIf you think developing information, including diagnostics, on your computer’s operating system and hardware is a tough task, you can relax. Here are 5 small, free applications, that make it easy to probe your computer system and create a detailed profile which can include hardware, installed software – motherboard, CPU and GPU specs, remaining drive space, and your operating system security hotfixes – and a lot more.

Belarc Advisor

Belarc Advisor is a free program that automatically generates a detailed audit report of the hardware and software on your computer. It records essential information such as, operating system and processor details, the amount of RAM installed, and drive specifications.


The report also includes a comprehensive list of the software installed on your system, as well as software license numbers and product keys. In addition, it lists the status of the Microsoft hotfixes on your system. If any hotfixes need reinstalling, you will be advised of this.

The results are displayed in a formatted HTML report. The report is clearly formatted for ease of understanding and divided into appropriate categories. Hyperlinks within the report allow you to quickly navigate to different parts of the document, find out more about a particular hotfix entry, or see where a listed software product is installed.

All of your PC profile information is kept private on your PC and is not sent to any web server.

System Requirements: Windows 8, Windows 7, Vista, 2003, XP. Both 32-bit and 64-bit Windows support.

LookInMyPC is a free application which, like Belarc Advisor, records essential information such as, operating system and processor details, the amount of RAM installed, drive specifications and so on. But, it digs much, much, deeper.


The following graphic shows a very small (I do mean very small) portion of a scan result, run on my test platform. The data shown here is pretty standard stuff.

  1. Hey Bill,
    I have not used any of these since switching over to Windows 8 RP so grabbed Speccy and PC Wizard 2012…portable of course 🙂

    I have to find a temp program to check my hard drives out because speccy works great and everything seems fine with the exception that it says my SSD hard drive is 128c

    Maybe it’s just a glitch in the program…Gotta check to be sure


    • Hey TeX,

      I’m running a smaller SSD (60GB), so your practice of going portable is looking increasingly more attractive.

      At 128 C (288 F), you could cook your breakfast on that HD. 🙂 Gotta be a glitch.

  3. Hey Bill – Nice article… good selection of system utilities. All will provide adequate info for conventional purposes. My main preferences for this type of software are portability, plus the ability to create and save reports locally. My software of choice has always been SIW but it’s difficult now to locate a version which is free, portable, and does not include bundling.

    I’m now (mostly) using HWiNFO which has portable versions available in both 32 and native 62-bit editions. Reports can be saved locally in a variety of popular formats, zero information on software though. HWiNFO also includes a nice hardware monitoring tool displaying lots of useful info, including core temps.

    I also utilize LookInMyPC portable on the odd occasion when additional info is required. Portability being a major consideration for anyone undertaking the role of ‘repairer’.

    Cheers mate… Jim

    • Hey Jim,

      Have to agree – HWiNFO is an awesome app. I’ve recommended it here 5/6 times but I can’t find an instance where I actually reviewed it.

      I’ll have to correct that. 🙂

      Good to hear from you.

    I use Speccy for the same ( also posted about it on EG along with Ccleaner ) as its simple to use for any novice users. Among all the screenshots posted above, it has the best UI according to me. Isn`t it, Bill?
