Check into WMI usage. You can pull BOATLOADS of information about a system with it.
Including all those ID numbers you were looking for.

I would suggest looking for MAC addys and maybe the windows product key?
MAC addys are supposed to be unique, it's possible (and rather likely now-a-days) that a computer has multiple NIC cards, but you can get at all of them with the WMI interface.

MAC address of NIC of your computer must be UNIQUE.

Following is the code to get the MAC address

//Requires a reference for System.Management

public string GetMACAddress()
{
ManagementObjectSearcher objMgmtSearcher;
ManagementObjectCollection objCollection;

objMgmtSearcher = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapter");
objCollection = objMgmtSearcher.Get();

StringBuilder strTable = new StringBuilder();

strTable.Append("<table><tr><td>Caption</td><td>Mac Adddress</td></tr>");
foreach (ManagementObject objMgmt in objCollection)
{
strTable.Append("<tr><td>" + objMgmt["caption"].ToString() + "</td>");
if (objMgmt["MACAddress"] != null)
strTable.Append("<td>" + objMgmt["MACAddress"].ToString() + "</td>");
else
strTable.Append("<td>-</td>");
strTable.Append("</tr>");
}
strTable.Append("</table>");
return strTable.ToString();
}

The reason I didn't put much reliance on the MAC is that many pieces of hardware nowadays support MAC-spoofing and thus you can produce duplicate MACs (although if that happened the network structure would be compromised let alone your software)

But more over someone could keep changing their MAC and you would not be able to track them.

Also, old NIC cards can have issues and lose their MACs (yes it does happen, physical corrosion on the card itself can cause bits to stick and other hardware issues)
