How to Mount an ISO image in Windows 7, 8, and 10
Windows 8/10 - right-click the iso file, select 'mount'.
Windows 7 or before, download and install 'WinCDEmu'.
You can double click the iso file to mount it. Or you can right-click the iso file, and select 'select drive letter and mount'.
============================
Virtually mount and access ISO files as a virtual device.
If
you don’t have a CD/DVD burner installed on your machine or you don’t
have media available to you (a blank CD-R/DVD-R), you can “mount” the
ISO file as a virtual drive. With this method, your machine will believe
that the file is a real disk drive, and you will be able to read files
from this “virtual disk.” This approach is advisable only for
installation of applications (such as Office) or minor system upgrades.
You will not be able to install an Operating System using this approach,
because the virtual drive would disappear at some point during the
installation.
There are several software options for the
virtual drive approach. Though they have not been tested and are not
supported by the VLSC team, customers report that
Daemon Tools and
Pismo File Mount offer such capability as well as
Microsoft Virtual CD Control Tool.
Sherman: Daemon Tools works well.
