Windows Installation is the process of setting up the Windows operating system on a computer. This can be done using a bootable USB drive or a DVD containing the installation files. During the installation, users will select their language, time, and keyboard preferences, and then choose where to install the system. After these initial steps, the installation program will copy files and configure settings. Once completed, users will create an account and set up their preferences. The computer will then restart, and Windows will be ready for use, allowing users to install applications and customize their experience.
