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.

This review is of Belarc Advisor v12. Please let us know if Belarc, Inc. has released a newer version and we haven't yet reviewed the update.

Belarc Advisor Basics

Belarc Advisor Pros & Cons

There's little not to like about Belarc Advisor:

Pros:

  • Small 4 MB download size and installation footprint
  • Completely free
  • Computer analysis is very fast considering the data being gathered
  • No toolbars, adware, or spyware included during installation
  • Results display in your default browser
  • Can copy data out of the results page with ease
  • Computer profile is not stored online, only locally (good if you're concerned about privacy)

Cons:

  • No summary page
  • No portable version (i.e., must be installed to use)
  • Computer profile is not stored online, only locally (bad if you want to easily share your data or want it stored in the cloud)

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.

There are a few user reviews of Belarc Advisor that suggest that the program doesn't find the proper Windows product key, but please know that these aren't real issues with this tool but are instead unfortunate results of specific Windows setups.
