When was the last time you knew the exact specifications of your computer beyond just the basics like RAM and storage? For most users, that knowledge ends with opening “This PC” or “System Properties.” But for IT professionals, advanced users, and even home users planning upgrades, deep system insights are crucial. That’s where Belarc Advisor comes in.
What is Belarc Advisor?
Belarc Advisor is a free Windows auditing tool that generates a comprehensive system profile of your PC. It examines both hardware and software details, retrieves software license keys, checks for missing Windows updates, and provides security vulnerability insights.
Unlike many online diagnostic tools, Belarc Advisor runs locally on your computer and does not transmit your sensitive information to servers. The output is displayed in a clean, HTML report inside your web browser.
