Windows Product Key

Is there anybody here can help me how to get/retrieve the "Windows Product Key" in code?

FYI: There is a freeware called "Magical Jelly Bean Keyfinder" that shows the Windows Product Key as well as the product key for Office.  I would like to do that using Visual Basic 6.

Thanks

Hello experts,

Sorry, I forgot just one more additional question to this:  How can I accomplish this technique on a "remote" machine?

Thanks again for your help.

why would you want to do this from a remote machine ( Sounds a bit dodgy like you are trying to get other peoples keys that dont belong to you or something ) ??

Well, I have just created a "Network Auditing Tool" that scans all computers on my network for auditing purposes. The data that my program collects are: MachineName, Description, IPAddress, OS,SP, DateInstalled, DomainRole, CurrentUser, SystemModel, BIOSInfo, Processor, Memory, Printers, NIC, Video, SCSI, etc. using WMI.

The only thing I was looking for was how to get the "CD-key" so that I can maintain a list of what XP Product Keys I have used and what I have NOT used.

Anyways, thanks for your help. I found how to do it using the "RegConnectRegistry" API

egl1044's version is more elegant by the looks of it with its copymemory API / function or library or whatever it is etc :)
