ISO Recorder has been conceived during Windows XP beta program, when Microsoft for the first time started distributing new OS builds as ISO images. Even though the new OS had CD-burning support (by Roxio), it did not have an ability to record an image. ISO Recorder has filled this need and has been one of the poular Windows downloads ever since.
With an advent of Windows XP SP2 and Windows 2003 the version 2 of ISO Recorder has been released, which intorduced some new new features including ISO creation and support for non-admin user.
Finally, in Windows Vista it became possible to address another long-standing request and provide DVD burning capability.
Since the very beginning ISO Recorder has been a free tool (for personal use). It is recommended by MSDN download site along with Easy CD and Nero and is used by a number of companies around the world.
