I am using the code below to get processor id:

System.Management.ManagementClass theClass = new System.Management.ManagementClass("Win32_Processor");
System.Management.ManagementObjectCollection theCollectionOfResults = theClass.GetInstances();

foreach (System.Management.ManagementObject currentResult in theCollectionOfResults)
{
    MessageBox.Show(currentResult["ProcessorID"].ToString());
}

Is processor ID a unique ID for every computer? I want to generate a random unique number for every computer to use as a AES crypto key. I don’t want to use MAC address because i know that MAC address can be changed.

    1. Processor ID is not guaranteed to be unique for every cpu or guaranteed to exist at all.
    2. Hardware can be replaced – you can’t change that fact.

    Suggestions:
    if you need to uniquely identify a machine – it is ok to use the processor Id or MAC address or both for uniqueness. (or any other hardware related number).
    but you must keep in mind you id the hardware – not the user, so if the hardware has changed it is much like if someone you know took a face lift and now you don’t recognize him.

    If you need to identify the user (which I think is better) just let him choose a username and a password.

    If you need to make sure that only one previously identified user is using your app, and your’e afraid he will be pirating your app.. the only way is having a server/central point.
