Hi Anna! Is this question in regard to a Toshiba Satellite laptop? If so, the software drivers shouldn't require a registration key at all. If you would be so kind as to let me know what drivers you're seeking, I'll try to help locate a legitimate copy for you which doesn't require this.
Thanks...I look forward to hearing back from you!
