Hi, Sorry for being thick, but I'm new to all of this. I have a Dell Inspiron 1501, but i don't fully understand what any of this will change? This laptop must be what is called a licensed one, because I can re-install Vista after formatting and not need to enter the serial key from the license sticker on the back of the machine. Does all of this reveal hidden options in the BIOS, or is it all simply to turn non-licensed laptops into licensed ones, so no key is needed? If there are hidden options in the BIOS, I'd be interested to reveal them. Thanks.
