computer
• In the past, Microsoft Windows was installed by disc, CD- or DVD-
ROM, or the floppy disc – and optical data carriers are also gradually
disappearing from the scene. Instead, the operating system is either
preinstalled on the system partition of a new computer or laptop, or
you acquire Windows directly online, complete with a digital
license, and download it yourself.

nowadays use a bootable USB drive. It’s quicker and more compact
that an optical data carrier, and so is perfectly suited for setting up (or
resetting) a system.
