Instructions on how to find serial numbers of Windows computers

The serial number is a unique code to identify your computer device, in order to prevent buying fake, counterfeit or used products in case the user wants to find out information from the manufacturer through this serial number. Each laptop will have a separate serial number. In case you need to install a driver or provide warranty service information, you will need this serial number. However, some people do not know how to search serial numbers on laptops, please follow the article below.

Note to users, how to check the serial number below can be suitable for different laptop models.

1. Serial number on the camera body, machine case:

For some laptops, we can easily check the serial number right on the camera body, when printed on a small sticker on the bottom of the device. Some other laptops, this information is printed directly on the device's cover. In case the device battery is removable, the serial number may be printed on a small sticker inside the battery compartment, below the battery pack.

For desktop models, we need to find the position on the back, top, or two sides of the case. However, we need to open the case because the serial number listed in the label is inside the case

If you still have the original box with the device, try to find the label because you can write the serial number on it.

2. Check the serial number via the CMD command line:

If the labeling case has been blurred and cannot see the serial number, there is a very simple way that is to use the CMD command line.

Step 1:

First of all, we open the Run dialog box and then enter the cmd keyword and click OK to access.

Step 2:

At the Command Prompt window interface, please type the command below and click OK to access.
