I had previously been using daemon tools to mount image files, but there isn’t a version for Windows 7 yet.  Someone I work with needed to mount an ISO in Windows 7, so I found another way, using PowerISO.  Power ISO is easy enough to use and did the job on 7, so I’m happy with it for now.

Given that Daemon Tools has become a bit of bloatware, I might stick with PowerISO.  We’ll see.
