Having an ISO file, how do you create a virtual CD drive?

https://www.howtogeek.com/howto/windows-vista/mount-an-iso-image-in-windows-vista/

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.
