Virtual CloneDrive
If you have an MSDN license you are flush with lots of ISO files. Maybe you want to burn them all to DVD's but I keep my collection of ISO's on my Windows Home Server (http://en.wikipedia.org/wiki/Windows_Home_Server). This saves me alot of time hunting through the pile of junk on my desk looking for a disc. However it does mean that I need software to mount the ISO. This software adds a virtual DVD drive to your computer allowing you to insert the ISO. The beauty is that it appears just like a normal DVD once mounted. . . The best piece of software I found for the job to date is Virtual CloneDrive from SlySoft (http://www.slysoft.com/en/virtual-clonedrive.html). Happy ISO Busting!
