Belarc Advisor is a free tool for Windows that analyzes installed Software and Hardware on your computer, missing and installed Windows HotFixes, Anti-Virus Status, and CIS(Centre for Internet Security) Benchmarks and then displays them all in your web browser. It gives a detailed information of each and every Hardware component and also displays the version of every software installed.
Once you have installed this tool, make sure you have updated it to the latest version. It will then begin to analyze your computer and create a profile.
After it has finished creating the profile, it will load up the results in your default Web Browser.
It will first display all hardware information such as, Operating System, System Model, Processor, Main Circuit Board, Drives, Memory Modules, etc. Then you will find details of Users, Printers, Bus Adapters, Multimedia, Communications and Other Devices. Next, you will see the list of missing updates that you need to install using Windows Updates. You will also find the date every Windows Hotfix was installed. Finally you will find all software and their licenses(with Key).
Unlike other tools, it crams all detailed information into one simple web page. And since it shows the information on a web page, it requires no additional system memory. Overall it is a lightweight and simple tool that can help you find every details about your system.
After using my laptop for around 6 month, the only thing I knew was that it has 3Gb of system memory. With Belarc Advisor I was able to find out that Slot ‘DIMM0’ has 2048 MB of memory and Slot ‘DIMM2’ has 1024 MB of memory installed. Enjoy!
