How to Get the Motherboard Serial Number in C and C++
If you are developing a software that requires a unique identification of a computer, you may need to get the serial number of the motherboard or the processor. The serial number is a unique string that can be used to register, replace, or find compatible parts for your motherboard. In this tutorial, we will show you how to get the motherboard serial number in C and C++ using different methods.
Method 1: Using WMIC Command
WMIC (Windows Management Instrumentation Command-line) is a tool that allows you to perform various operations on Windows systems using WMI (Windows Management Instrumentation) queries. One of the operations you can perform is to get the product name, manufacturer name, serial number, and version of the motherboard using the baseboard class.
To use this method, you need to do the following steps:
Open a command prompt window by pressing Win + R keys, typing cmd, and clicking OK.
Copy and paste the following command into the command prompt window, and press Enter:wmic baseboard get product, manufacturer, serialnumber, version
You will see the output similar to this:Manufacturer Product SerialNumber Version
ASUSTeK COMPUTER INC. P8Z77-V LX 130706222600263 Rev X.0x
The SerialNumber field is the motherboard serial number you are looking for.
Method 2: Using WMI Queries in C and C++
If you want to get the motherboard serial number programmatically in C or C++, you can use the WMI queries to access the baseboard class. WMI queries are written in WQL (WMI Query Language), which is similar to SQL (Structured Query Language). You can use the Get-WmiObject cmdlet in PowerShell to test your WQL queries before using them in your code.
To use this method, you need to do the following steps:
Open PowerShell or Windows Terminal by pressing Win + X keys and selecting it from the menu.
Copy and paste the following command into PowerShell or Windows Terminal window, and press Enter:Get-WmiObject win32_baseboard Format-List Product,Manufacturer,SerialNumber,Version
You will see the output similar to this:Product : P8Z77-V LX
Manufacturer : ASUSTeK COMPUTER INC.
SerialNumber : 130706222600263
Version : Rev X.0x
The SerialNumber property is the motherboard serial number you are looking for.
To use this query in your C or C++ code, you need to include the wbemidl.h header file and link with the wbemuuid.lib library. You also need to initialize and uninitialize the COM library using the CoInitializeEx() and CoUninitialize() functions. Then, you need to create an instance of the IWbemLocator interface using the CoCreateInstance() function and connect to the WMI namespace using the IWbemLocator::ConnectServer() method. Next, you need to set the security level using the CoSetProxyBlanket() function and execute the WQL query using the IWbemServices::ExecQuery() method. Finally, you need to enumerate the results using the IEnumWbemClassObject::Next() method and get the value of the SerialNumber property using the IWbemClassObject::Get() method.
The following code snippet shows an example of how to get the motherboard serial number in C++ using WMI queries:#include <iostream>
