I was using this command for fetching serial number

(Get-CimInstance -ClassName Win32_BIOS -Property SerialNumber).SerialNumber

and this is what the response/output is

To Be Filled By O.E.M.

May I know how to fix this, please?

    Hi minnu

    I am Dave, I will help you with this.

    That error indicated the system manufacturer has not provided that information in your BIOS, it is very common

    Click your Start Button, then just type msinfo and press Enter

    On the resulting system information window, do some of the entries there also have that 'To Be Filled By O.E.M.' error?

    Hi minnu

    There should be a command to get the hardware MAC address, that would be unique to each device.
