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. If you already have a backup of the computer and files. You have an activation product key. The device can start from a USB flash drive, and non-essential peripherals are disconnected, then you can skip this part and jump to the bootable media creation and a clean install process. 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. If you need to back up your documents, pictures, and other important files, you can upload the data to OneDrive or another cloud storage service.
