When you download Windows from Microsoft Store, you have two options: You can download a collection of compressed files, or you can download an ISO file. An ISO file combines all the Windows installation files into a single uncompressed file. Then simply install Windows onto your computer directly from your USB or DVD drive. When you download the ISO file, you must copy it onto a USB or DVD. When you're ready to install Windows, insert the USB drive or DVD with the ISO file on it and then run Setup. This allows you to install Windows onto your machine without having to first run an existing operating system. If you change the boot order of drives in your computer's BIOS, you can run the Windows installation directly from your USB drive or DVD when you first turn on your computer. Please see the documentation for your computer for information about how to change the BIOS boot order of drives.
