Get detailed hardware, software and security information about your computer, with Belarc Advisor
Belarc Advisor is a free application that will detect your hardware, software and security details after a thorough scan.
The program presents information that finds about your computer on a single HTML page that is loaded from your computer (nothing reaches any server, it all remains private).
Using Belarc Advisor you can find details about your drives (including their health report), your USB connections, CPU, GPU, software installed including the exact Windows version and antivirus status, BIOS details, security patches you need to apply, network inventory, and more.
Note that the program can be used for free only on a personal PC — not on enterprise, education or military networks or anywhere else. For such a use you need a commercial license.
