A system image on Windows 10 is an exact copy of a drive. By default, a system image includes the drives required for Windows to run. A System Image includes Windows and your system settings, programs, and files. You can use a system image to restore the contents of your computer if your hard disk or computer ever stops working. When you restore your computer from a system image, it’s a complete restoration and you can’t choose individual items to restore, and all of your current programs, system settings, and files are replaced with the contents of the system image.
