Activation strategy is a dominant way to software anti-piracy nowadays,but there is not a proper ID which can identify the client.The ID of all hardwares in the client was taken as the ID,not only one harware.It was got by WMI.The weight was used to solve the problems that there is no ID in some hardware or that there is high reiteration ration in the market.Different hardwares had different weights.Every hardware's hash value was got using MD5,then those hash values was taken as the only ID.The packet filled with all the hardware's hash values was sent to the server,and then the server could get the information in the client.
