A computer serial number is a unique code assigned for identification of a single unit. It’s often required to get the warranty service when you got a problem with your computer. Usually you can find it out on a sticker adhered at back of your computer.
But there are easier alternative ways to find the same information without turning your computer upside down or sliding your body underneath the desk.
Open Command Prompt and run the following command:
wmic bios get serialnumber
If you need both serial number and model number of your computer, run the following instead which gives you both info at once.
wmic csproduct get name, identifyingnumber
You can also run the following cmdlet if you are a fan of PowerShell.
Get-WmiObject -Class Win32_BIOS
If you just want to find out the model of your computer, run msinfo32 from Win+R or Command Prompt window.
That’s about it.
