{
string cpuInfo = String.Empty;
string temp = String.Empty;
ManagementClass mc = new ManagementClass("Win32_Processor");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject mo in moc)
{
if (cpuInfo == String.Empty)
{// only return cpuInfo from first CPU
cpuInfo = mo.Properties["ProcessorId"].Value.ToString();
}
}
return cpuInfo;
}
