How to enter serial number into wmi

Adam Kennett 0

Hello,

I need to enter the motherboards serial number into WMI, currently when I use:

CMD - wmic bios get serialnumber

Powershell - Get-WmiObject win32_bios | select Serialnumber

I get a return of 'Default String'. I have the serial number listed on the motherboard itself (Gigabyte Board) i just need it entered, any help would be greatly appreciated. All I can seem to find online is how to read back the serial number, not enter a new one.

Changing the motherboards' serial number is handled by modifying the BIOS, and usually done using an OEM tool.

If you're an OEM yourself, try contacting the manufacturer.

Your motherboards' manufacturer does have an integrators' toolkit, but it requires a user id and password to get to the web page.

Hi Rich,

Thank you for your reply. Ive reached out to Gigabyte regarding this and they keep insisting you can use Powershell or CMD to change this.

Hello,

You can used Window build in tools like CMD and power shell.

Using powershell run as administrator: Please type :

Get-WmiObject Win32_bios SerialNumber.

Note serial number must be at Type 1.

2. Under Window CMD (run as Administrator):

Type: wmic bios serialnumber

Regards,

Gigabyte

That looks like a canned response. The Get-WMIObject (note the "GET" verb!) won't modify anything. The WMIC information they gave you does the same thing as the Get-WMIObject and it doesn't change the serial number, it just returns the value.

There is a Set-BIOS module for PowerShell. It's a 3rd-party module and its description doesn't mention the brand of motherboard you're using.

There're also tools like RWEverything (http://rweverything.com/). Again, 3rd-party.

If you pursue this, be sure to read all the information you can find about the tool/code before you start writing (or destroying) information in the BIOS!

I had the same thoughts on it being a canned response, the response I posted there is one of several back and forth, they just kept replying with the same answer.

Appreciate the link to RWEverything, ill set it up in a VM and have a look.

Cheers.
