A clean installation of Windows 10 is the process of erasing the hardware and setting up a new fresh copy of the platform when a computer has a problem. For example, you can resolve performance, memory, startup, shut down, and apps issues using this method. Also, it's perhaps the best approach to remove viruses and other types of malware, and it can help to improve battery life.
In addition, it's an excellent solution to remove preloaded bloatware (unnecessary preloaded software) from Windows 10. You can use this method to decommission a computer without giving away your data. Or you can set up a new installation after replacing the hard drive. Furthermore, if you had the same setup for some time, a clean installation is the recommended option to upgrade to the latest version of Windows 10 or upgrade from an older version (such as Windows 7 and Windows 8.1), minimizing the risks of problems during and after the process.
In this Windows 10 guide, we will walk you through the complete process to perform a clean installation. As you prepare to proceed with a clean installation of Windows 10, it's recommended to complete some essential tasks to minimize issues and potential data loss.

The install process of Windows 10 deletes everything on the drive, which means that backing up the entire device (or at least your files) is a crucial step unless you don't have anything important you want to keep.
You should create a temporary backup to revert the settings or recover files if something goes wrong during the installation. You can choose many different solutions, but the easiest way to create a full backup is to use the legacy System Image Backup tool available on Windows 10.
It's a deprecated feature, but it continues to work. The tool is also available for Windows 8.1 and Windows 7.
