Q: I downloaded Vista from the Microsoft Web site, and I can't
find installation instructions. The file extension is .iso, so
it's not an executable. I tried using the Run command and the
install from Add/Remove Programs, but they won't run it.Don
Boudreaux  A: An ISO image is like the disk drive image backup
created by Ghost or DriveImage. It holds the exact contents of
the CD or DVD, byte for byte, without regard for the way those
bytes are organized into files, folders, and so on.  You need to
burn the file to a physical DVD, or you could use a program that
lets you open the ISO image directly as a virtual DVD. Daemon
Tools (www.daemon-tools.cc) is a free example of the latter. But
you're probably better off burning a physical DVD so that you
can simply boot from it to install. You can use just about any
commercial DVD burner to do that.
