Your PC's serial number, sometimes called service tag, is an important piece of info that you should keep handy, especially when you're troubleshooting or calling up tech support. Here's a one-step trick for finding it.

Launch the Command Prompt by pressing Windows Key + R to bring up the Run dialog, typing in cmd, and hitting Enter. (Or launch it using any other method you prefer.) Then, type in the following command and press Enter again:

        wmic bios get serialnumber
    

This displays your computer's serial number instantly. Note it down for future use. That's all there is to it!

The command only works on Windows 7 through Windows 10 because these Windows versions have the WMIC utility built into them. If you want thorough information about every aspect of your PC, we recommend using Belarc Advisor.

By the way, the serial number is also available on the hardware itself, but it's usually located in a hard-to-access place, such as on the back of the CPU. Thanks to the WMIC method, you won't ever have to crouch behind the computer table or open up the hardware. You can see it right on your screen at any time!
