Ok, before i start id just like to say im sorry of this has been talked and explained time and time before. im not too fluent with computers and the wealth of knowledge on the forums is a bit mind boggling. Basically i need to activate my windows 7 build 7600. Without modifying the bios or motherboard etc. and i was wondering if there was a way to do it via a product key or crack that doesnt expire Again im sorry if this has been answered numerous times and am thankful for any input cheers
