Как вариант - это использовать уникальные настройки биоса. Подключаете пространство имен System.Management и используете из нее фичу Win32_BIOS. Примерно вот так:

using System.Management;

string UniqueMachineId()
{
StringBuilder builder =newStringBuilder(); String query ="SELECT * FROM Win32_BIOS";
ManagementObjectSearcher searcher =newManagementObjectSearcher(query);
foreach(ManagementObject item in searcher.Get())
{
Object obj = item["Manufacturer"];
builder.Append(Convert.ToString(obj));
builder.Append(':');
obj = item["SerialNumber"];
builder.Append(Convert.ToString(obj));
}
return builder.ToString();
}
