If you purchased Microsoft Windows from Microsoft Store, and downloaded a collection of compressed files or an ISO file (containing Microsoft Windows setup), you can use that ISO file to install Microsoft Windows. An ISO file combines all the Windows installation files into a single uncompressed file. ISO file can not be used directly. You have to burn that ISO file to DVD or USB disk.
