Step-by-Step Tutorial on Finding the Serial Number on Windows 11

In this section, you’ll find steps to get your Windows 11 serial number using both the Command Prompt and PowerShell. Follow each step carefully to ensure you retrieve the correct information.

Step 1: Open Command Prompt

Open the Command Prompt by typing "cmd" in the search bar and hitting Enter.

After launching Command Prompt, a black window will appear. This program allows you to execute text-based commands to perform specific tasks.

Step 2: Enter the Command

Type the following command: "wmic bios get serialnumber" and press Enter.

This command queries the BIOS to retrieve the serial number of your Windows 11 machine. It ensures that you get the exact number from your hardware settings.

Step 3: View the Serial Number

Look at the output in the Command Prompt window; your serial number will be displayed under "SerialNumber."

After hitting Enter, you’ll see a short list with your serial number. It’s that simple! This serial number is unique to your device.

Step 4: Open Windows PowerShell (Alternative Method)

Open Windows PowerShell by typing "PowerShell" in the search bar and hitting Enter.

Windows PowerShell is another tool similar to Command Prompt but more powerful. It can also retrieve your serial number using the same commands.

Step 5: Enter the PowerShell Command

Type the same command: "wmic bios get serialnumber" and press Enter.

Once again, this command will pull your serial number directly from the BIOS, ensuring you get accurate information.

Step 6: View the PowerShell Output

Look at the output in the PowerShell window; your serial number will be displayed just like in Command Prompt.

After you press Enter, the serial number will show up on your screen. This confirms that you can use either tool for the same result.

After completing these steps, you’ll have your Windows 11 serial number. You can use it for tasks such as verifying your warranty, troubleshooting, or support requests.
