Find serial number of compute using command prompt

Sometime you want to know serial number of your laptop or desktop and it is problematic everytime when you need it you have to check in back side . and there are some laptop in which serial number is   behind the battery so you need to shut down the system.
  So i am going to tell a command by which you can easily find the serial number. For this you have to follow some simple steps:
1- open command prompt ( in search type cmd)
2-just type following command : wmic bios get serialnumber
3- press enter and you will get serial number
WMIC (Windows Management Instrumentation Command-Line)

To retrieve model name of the computer run the following command from command line

wmic csproduct get name

This code doesn’t return information for all computers, but I’ve found it very usefull where its available.
