You cannot add it manually unless it is a Microsoft device. Usually it will be added automatically when you use a Microsoft account to setup windows.

I followed your excellent directions, a number came up at the end, I was SO happy! When I tried to register it, it said "that # isn't recognized." I'm sure it's on my end, but 1 hour of trying, I had to give in. Can you maybe help me? Your description of "how-to" , is amazing.

@Debbe I Brown adding a serial number manually is only for Microsoft devices, like Surface laptops. If yours is another manufacturer it will not work.

Method 1: Using Command Prompt (fastest)

Press Windows + R, type cmd, and hit Enter.
In the black Command Prompt window, type:
```
   wmic bios get serialnumber
```
Press Enter → Your system's Serial Number will appear.

Method 2: Using PowerShell

Press Start, type powershell, and open Windows PowerShell.

Run this command:

   Get-WmiObject win32_bios | select SerialNumber

The serial number will be shown.

Method 3: On device

Laptops: Flip the device, check the bottom or under the battery (sticker/engraved).
Desktops: Check the back panel or side of the tower.
Surface devices: On the kickstand, under the keyboard, or in Settings.

Method 4: In Windows settings (some OEMs)

Go to Settings > System > About.
Scroll to Device specifications → Sometimes shows serial number (depends on manufacturer).
