I use Windows sometimes and its very useful to be able to mount CD/DVD image files rather than having to waste a disc burning them to physical media.
Of course, this functionality is included with most free operating systems like OpenBSD and various Linux distributions. However, on Windows, most of the well-known applications with this capability are commercial shareware (DaemonTools, Alcohol 120%).
While its not Open Source, I came across SlySoft Virtual CloneDrive. This is a small freeware application which can mount various formats of CD/DVD images. It doesn't have any annoying nags and works just fine.
