IDM is a download accelator. By using this software we are able download from the Internet at a high speed.But when we are downloading the software from its official site it is not a full version. That is a 30 day trial pack. After these days are past it will ask you to enter serial key or to buy. So here is the process to make any downloaded IDM full version.After making this it will be registered for lifetime and not ask to register it further.
