I have found a link:
http://www.codeguru.com/forum/showthread.php?t=249788

I think I will go for checking the BIOS SerialNumber. In the link it seems to fail when doing this on Windows 98 or earlier but if a fail meens an emty string like: "" that will work for my purpose.

They refer to get the BIOS Serial like below but when gooling on that, I am not sure if I can find anything helpful of how to return this serial number.
I use VC++ 2008 Express Edition

GetBIOSSerial(); //Is this a call,  I cant find out if any namespace goes with this

I have come up with a code that look like this that is supposed to return the motherboard serialnumber.
The number that is returned is: "123456789000"

I wonder if that really could be correct or perheps do I miss something in the code. I am looking for a unique serial number ?

queryEnum = queryCollection->GetEnumerator();  
 
while(queryEnum->MoveNext())
{  
    objMgmt = queryEnum->Current;  
    MessageBox::Show(Convert::ToString(objMgmt->GetPropertyValue("SerialNumber")));

If you post the complete program (or some test code) then we can test it on our computers to see what it returns.

Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.

Yes, that would be more than nice.
I think this would be the complete testcode if I dont miss anything out.

I think this would be the complete testcode and see what this MessageBox returns.
You would have to add the reference System::Management in "Add New Reference"

using namespace System::Management;

The part I replace most often: is the motherboard(usually in conjunction with PSU). Those thing short out all the time, and now I have piles of them!

So be wary about how you use that. The only reason I can find, to use it is to block suspected bots off something like a MMORPG for a few hours, till the lag drops.

This is true, I am checking for possibilities and in the end, I will be that careful to see what can be possible or it wont be, how to define things etc...
