Nero is one such popular and mostly used program used for cd/dvd burning by large number of people, I still remember the express version of nero which was used to come with cd writers Samsung and LG some time back. Now you can get the latest version of nero for free with limited but essential features like cd / dvd burning.

Since it is the limited free version which offers very basic but important features like burning and copying functions, if you want all the features and functionalities then you will need to upgrade to nero 9 full version.
