Warning: A refresh on Windows 10 will help you reinstall Windows 10. However, it will remove the applications and drivers that you have installed and your personal settings will be changed back to default as well. It will also remove applications from your computer manufacturer but the apps you installed from the Windows store will remain.
A reset on Windows 10 will help you reinstall Windows 10 and remove ALL your personal files. The drivers, the applications, the personal changes that you made to settings, and the applications installed by your computer manufacturer will be removed as well. However, if your computer came with Windows 10, apps from your computer manufacturer will be reinstalled.
Therefore, it is strongly suggested that you back up your important files and applications before you do a refresh or a reset on your computer.
