Many times users get the Windows setup disc with the purchased computer system but sometimes many branded computers do not come with any setup or repair disc. Installation media may also come handy if you are facing problems in your computer system and want to repair Windows installed in your device. You can also upgrade your existing Windows version to a new version using the installation media. Once you create installation media, you can boot using it and then you can format existing partitions and perform a fresh installation of Windows in your machine. If you want to format and clean install Windows operating system in your computer system, you need an offline ISO file (disc image file) of Windows to create an installation media such as bootable USB drive or a DVD.
