How to Enable a CPU Serial

The processor in a laptop or desktop computer is called the CPU. The CPU has a specific serial number assigned by the manufacturer. Finding the serial number for your computer's CPU is done by running a command from a DOS window. This command is called the Windows Management Instrumentation Command Line (WMIC). You can run the command at the DOS prompt manually or by creating a batch file.

Instructions

Run Command Manually

1. Click the "Start" button and then type "cmd" into the search box. Press the "Enter" key to open a DOS window.

2. Type "cd.." and press the "Enter" key. Repeat this step to go to the root of the C drive.

3. Type "wmic bios get serial number" and press the "Enter" key. Wait a few seconds for the process to run and the result will be displayed on the screen.

4. Make a note of the serial number on a piece of paper for future reference.

5. Repeat this process to obtain the serial number for the CPU in any laptop or desktop computer system that is running Microsoft Windows.

Create Batch File

1. Click the "Start" button and type "notepad" into the search box. Press the "Enter"key to open Notepad.

2. Type "cd.." and press the "Enter" key. Repeat this step three more times to create three lines.

3. Type "wmic bois get serial number" and press the "Enter" key. Type "pause" and press the "Enter" key.

4. Click the "File" drop-down menu and select the option for "Save As." Save the file as "serial.bat" to the desktop.

5. Double-click the "serial.bat" file to run the command to see the serial number.

Tips & Warnings

• Copy the "serial.bat" file to a flash drive to run the command on other computers.
