GLOBALLY UNIQUE properties

[ossama]

hello,
i am writting a program that is will work only in my PC , so if i run that program from my pc it will work,but it will not work on any other machine,so i thinked of properties (of the pc) that are globaly unique like CPU ID, motherboard ID , chipset id ,....
is it possible to do this ? or if you have better idea please tell me.
thank you.

 No betters ideas - only Data sheet (on cpuid for example)

[ossama]

is CPUID unique for every machine in the world?

[Adamanteus]

 No  :dance:

Ossama,

I guess you are looking for something like Windows Product Activation collecting information from your computer's components.

As a first trial, how about getting the volume serial number(s) of your hard disc?  I guess it's not the best idea to solve your problem but it worths to do a trial as an exercise.

Vortex,
              I am trying to understand your question, but everyone that wants to know CPUID, motherboard ID wants to know WPA ? I dont think so. Because who knows CPUID etc. is near to know my WPA. Is it right ?

I am afraid this not a simple task. Have a look at this article :

Ok, i saw it. I have no problems with anything. I bought all things i have. But i remember i tested in my computer an exemple (from Michael if i am right ) to get CPUID and i dont know what more and i had no problems. I didnt think it was to make bad things in my computer. Do you think if i want to know CPUID is it because ... ??? I think it cannot be generallized.
Its all.

Have i nice night/day

Windows Product Activation checks eight different categories of hardware:

Display Adapter
SCSI Adapter
IDE Adapter
Network Adapter (including the MAC Address)
RAM Amount Range (e.g. 0-512 MB)
Processor Type and Serial Number
Hard Drive Device and Volume Serial Number
Optical Drive (e.g. CD-ROM)

but how can i get some property (serial number for example) from these objects (for example, how can i get the serial number of the hard disk within masm)

There are few things that will work here, each motherboard may have a different method of extracting the serial number so that would be a lot of work. CPUID has nothing unique to extract. I would look at the following key...

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ProductID

It should be unique to your PC.

hi donkey,
what is this key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ProductID
ProductID of what?

[Adamanteus]

I'm thinking he mistaken a little bit, mean the key :
HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System

[Tedd]

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ProductID
contains the registration number for your windows installation (you can see it under "Registered to:" in the System Properties dialog.)
It should be unique for each windows cd (i.e. if you use the same cd on two machines, they will have the same id.)

HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System
has information about the bios/pci/cpu, which can be useful, but many machines will have similar sets of components, especially if they came from the same vendor.


Maybe take all of them together as one long string, then hash that to obtain an identifier.

[ossama]

so we cant obtain globaly unique property from ProductID and system.

Tedd, how can i make the 'hash'?
