Anything goes with this one, I personally can't figure it out.

Clue: Uses random numbers to (attempt to) prevent keygenning =P

Disable start and end nags, enable disabled button, rename 'Register' button to 'Registered to Shadow', change unregistered to 'Registered to Shadow!'. All of this is completed automatically when you find a correct serial. Then find a way to allow other people to activate it(loader, keygen, etc.)

How would you generate keys yourself, if you're just comparing the serial to random values? :)

I'm not sure of the wiseness of keygenning at this point. It'd be much more straightforward to patch or self-keygen, I think.

If you can insert a hook on the native GetTickCount() function (in kernel32.dll), you can retrieve the random seed. From there you easily can generate a key.

Not sure whether I'll post a solution though.

Also remember that the random number is not the entirety of the serial generation process. it's just... an added bonus =P

More easy to patch!!

MORE easy. Still not really easy. For example, where is the serial verification process within the code?

GO deurus =P. Solution works perfectly, all criteria solved. Thanks man! However, a keygen can still be sent as a solution. Good luck!
