Find Laptop/Computer Serial Number using CMD Prompt

The serial number sticker on my laptop was damaged and it was un-readable. But there is an easy alternative way to find the serial number without turning your machine upside down :P

If the OEM has entered the serial number of the machine in the BIOS, it can be retrieved using a simple WMI query. We can execute this WMI query in command prompt using:

C:UsersusernameDesktop> WMIC BIOS Get SerialNumber > LaptopSerialNumber.txt

(Tip: using > FileName.txt with any command in command prompt saves the output to the specified file)
