Belarc Advisor is one of our favorite free system information tools. It’s fast, easy to use, and gives you a surprisingly digestible report of what makes up your computer system.

One popular category that Belarc Advisor excels at is providing software license information. This means you can use it to find the correct product key or serial number for your installed programs.

Similar to other system information programs, Belarc Advisor gathers information regarding things like any software installation, video card, CPU, RAM, software update, as well as motherboard and network information.

Our Thoughts on Belarc Advisor

We really like Belarc Advisor and we’ve been using it for a long time. We’d consider it the “original” system information program. We’re not aware of any similar program that’s been available and continuously improved upon, for anywhere near the length of time that Belarc Advisor has been. We used it way back in the Windows 95 days!

Obviously, it’s great that it’s a completely free program but that’s not at all why we love it so much. Belarc Advisor is quick, accurate, and produces more detailed information that many similar programs, some of which dare to charge for a similar feature set.

If you’re in need of a program that can quickly and accurately produce detailed information about your computer, Belarc Advisor is an excellent choice. We’d also recommend that you use Belarc Advisor for any product key finding needs you might have, especially for Microsoft Windows and Microsoft Office licenses.
