I would like to add a small and simple protection for my program. It's not a 
program to be likely hacked within the future, but I would like to add some 
protection and 'activation' . This activation will be done by entering a unique 
key provided by me.

 I have done this in the past by retrieving the hard disk serial (and mybe some 
other serial numbers) and use this number to generate a validation code. This 
would trigger to create a register key that could be used to validate the 
program at startup.

However, this was, some time ago on windows 2000 machines.

now things might have changed with windows vista / 7

Where within the windows 7 / vista register is one allowed to create a 
validation key.

Maybe someone could direct me to some open source example to generate a 
validation key?  I've done some googling, but only finds some commerial 
products without source.   Also a snipled of code shoul be welcome as a start.

regards

andries
