Today Nero decided to give as free one of their basic versions, Nero 184.108.40.206. They say this is a restricted version since it has only data burning and disc copying features for CDs and DVDs, advanced features being available in the full version.
Nevertheless, Nero's only thing I would use is the burning engine (I don't care about the backup or other utilities they offer in the full version) and this comes as handy as possible.
You can enter your email and receive the license here - Nero 9.4 (free). I don't know if this is a time-limted thing or if they're going to have this free product from now on, but given that there are so many free CD/DVD burners out there, it's probably a wise marketing decision from their part.
