a disc image creator or a disc image mounting software or just a generic CD/DVD burning software?
Windows Explorer since Windows [strike]7[/strike] 8 and above will mount disc images and make them able to read. any DVD burning software should create disc images. but Nero has been the best disc burning software i've used for years now.
which are you trying to do?
<Mod note: Windows 7 cannot natively mount iso's>
