    My Opinion

    You may make one copy of the ISO file on a disc, USB flash drive or other media in order to install the software on a computer. Once you have installed the software on a computer, the license terms that accompany the software apply to your use of the software and replace these terms. The license terms for Windows 7, once accepted, permit you to make one copy of the software as a back-up copy for re-installation on the licensed computer. If you do not delete the copy of the ISO file you made to install the software on your computer, then the copy of the ISO file constitutes your back-up copy. So now you can easily Install Windows 7 right from your Portable USB drive or DVD.
