QuestionEvery time I format my system, I get a different MAC address (Windows XP, VISTA and Windows7). Why I am not getting same MAC every time? Pin

Hello friends,

I am using MAC address to implement licensing in my application. As far as I know, MAC address of every system is unique and is very commonly used for licensing purpose.

For giving license of my application, I generate a unique key based on MAC address of a particular system and send that key to the customer. But the problem is that every time I format my system, I get a different MAC address. Doing this is problematic as every time customer format his system, he will need a new key (as his MAC address will also change on formatting his system).

Another problem is that if someone have two OS say XP and VISTA on his machine, he'll need two different keys to activate the license on both of the OS.

What I want, I get same MAC address even though customer keep on formatting his system (so that he can use same key every time). Also I get same MAC address on all the Operating Systems on a single machine (so that he can use same key on all the Operating Systems on his machine). Is it possible to do so? If yes then how? If not then why not? Please help me.

Right now I am using below code to get MAC address of a system:

std::string strMACAddress;
try
{
	PIP_ADAPTER_INFO pAdapterInfo = NULL;
	ULONG ulOutBufLen = sizeof (IP_ADAPTER_INFO);
	pAdapterInfo = new IP_ADAPTER_INFO();
	if (pAdapterInfo == NULL)
	{
		return;
	}

	// Make an initial call to GetAdaptersInfo to get
	// the necessary size into the ulOutBufLen variable
	int iResult = GetAdaptersInfo(pAdapterInfo, &ulOutBufLen);
	if ( iResult == ERROR_BUFFER_OVERFLOW )
	{
		delete pAdapterInfo;
		pAdapterInfo = new IP_ADAPTER_INFO[ulOutBufLen];
		if (pAdapterInfo == NULL)
		{
			return;
		}
	}

	if ( iResult != ERROR_SUCCESS )
	{
		iResult = GetAdaptersInfo(pAdapterInfo, &ulOutBufLen);
		if ( iResult != ERROR_SUCCESS )
		{
			delete pAdapterInfo;
			pAdapterInfo = NULL;
			return;
		}	
	}

	strMACAddress = pAdapterInfo->AdapterName;
	delete pAdapterInfo;
	pAdapterInfo = NULL;
}
catch (...)
{
}


Thanks in advance,
Best Regards
Aseem
