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 Microsoft Store, you have an additional choice to make: whether to download a collection of compressed files or to download an ISO file. An ISO file combines all the Windows 7 installation files into a single uncompressed file.
If you choose to download an ISO file (so that you can create a bootable file from a DVD or USB flash drive), copy your Windows 7 ISO file onto your media and, run the Windows 7 USB/DVD Download Tool. After you do this, you can install Windows 7 onto your computer directly from the USB flash drive or DVD.
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 drives.)[ How To Use ]
