When you choose to download most software from the Microsoft
Store, you have the option of using Download Manager or downloading from
your browser. However, when you purchase Microsoft Windows 7 from

the USB flash drive or DVD.
Note: When you download the ISO file, you must copy the
file onto a USB flash drive or a DVD to install Windows 7. When you're
ready to install Windows 7, insert the USB flash drive into your USB
port or insert your DVD into your DVD drive, and then run Setup.exe from
the root folder on the drive.
The advantage to following this process and creating bootable media
is that it allows you to install Windows 7 without having to first run
an existing operating system on your machine. If you change the boot
order of drives in your computer's BIOS, you can run the Windows 7
installation directly from your USB flash drive or from a DVD when you
first turn your computer on. (Please see the documentation for your
computer for information about how to change the BIOS boot order of

installing the Windows 7 software, the copy of the ISO file counts as
your one back-up copy.
