Use Windows 10’s built-in tool
The easiest way to back up your PC is to use the tools in Windows 10 (or other versions of Windows). To access them, type Control Panel in the Start menu, then where it says ‘System and Security’, select ‘Backup and Restore (Windows 7)’. Ignore the fact it says ‘Windows 7’, since it can be used on later Windows versions. To start the step-by-step backup process, click ‘Set up back-up’.
