What do you use to extract the contents of an ISO after you've downloaded it from MSDN Subscription?
All the times I have done a DL the file was an ISO.
If your question is what to do with it: (i.e. you don't know what an iso file is)
You burn it to a CD/DVD. That is a disk image.
depending on the ISO, i'll either burn it to disc or mount it to a virtual drive and install from the virtual drive (not really an option if the ISO is an OS).
Alex Feinman's (free) ISO Recorder if I want to burn it. WinRAR if I want to just open it.
To look what's in the ISO you can:
- mount ISO image as a drive
- burn ISO on a cd/dvd
- use WinRAR to look at / extract the contents
I usually mount the ISO to a virtual CD/DVD drive. I've used the following freeware packages at various times. As far as I know these install no toolbars, spyware or other junk. I currently usually use MagicISO's - pretty much just works.
I don't know what the situation is for these on Vista or x64 (I'm still largely on 32-bit WinXP).
Microsoft's unsupported Virtual CD tool:
MagicISO's MagicDisk

SlySoft's Virtual CloneDrive:
Of course, I can't vouch for any of these other than to say I've used them successfully - your mileage may vary.
http://www.imgburn.com/ is great free ISO burner, can also verify the burned disc.
If you are running Vista, (I have found) a lot of the virtual drive emulators do not work on Vista, but one that has worked on Vista for me is Softpedia's freeware Virtual CloneDrive.
I use the free version of Alcohol 52% - it lets you mount the ISO's as virtual CD drives. This works great in Windows 7, Vista, XP, and 2003 & 2008 versions of server.
