What is the serial number of my Windows PC, laptop, tablet, etc?

When you have problems with your Windows laptop, tablet, or PC, and you access the support website of its manufacturer, you are asked to enter the exact model name or the serial number of the device. If you do that, you get access to the correct drivers for your Windows device and the appropriate support options for it. Here is how to find your serial number, as quickly as possible, straight from Windows:

Open Command Prompt or PowerShell and use this command

The first step is to open either PowerShell or Command Prompt (depending on which you prefer). Type the command WMIC BIOS GET SERIALNUMBER and press Enter on your keyboard. You get results similar to the screenshot below, made in PowerShell.

The same result is returned when you open Command Prompt and run the command: WMIC BIOS GET SERIALNUMBER.

This command works and returns results when it is used on PCs made by a specific manufacturer like Lenovo, HP, Dell, ASUS, Acer, and so on. If you run it on a custom-made PC like a desktop computer that you have built, the command returns an empty value for the SerialNumber.

What did you need the serial number for?

Now you know the serial number of your Windows computer or device. Before closing this tutorial tells us why you needed it and how you used this information. Comment below and let’s discuss.
