In this video, I show you how to check laptop details or PC specs on Windows 10/11 smartly like an expert—especially if you’re about to buy a used or refurbished laptop. The usual Settings > System > About method is fine, but it’s limited and yes, it can be tempered. So I walk you through the advanced ways I personally use to verify the real configuration so no one can cheat you. First, I use Run (Windows + R) and open full System Information with msinfo32, where you can see deeper details like system model/SKU, BIOS info, RAM, and security features like virtualization, Secure Boot, and more. Then I cross-check the same specs using CMD with the systeminfo command—matching results across methods is the best way to confirm the info isn’t fake. After that, I show real-time CPU and RAM statistics in Task Manager (Performance tab), and even verify RAM speed using a WMIC command. Finally, I share a simple trick to estimate the real age of a laptop by checking the Windows folder “Created” date, and I recommend checking Device Manager for driver details before buying.
