Under“Reset this PC,” click “Get started.”
Choose the "Keep my files" option in the popup message. Keep in mind, after this step, your device will update to the latest Windows 10 version.
If you are upgrading your PC from a previous version of Windows to Windows 10, you will see a warning message stating that you won’t be able to undo the upgrade or rollback to the previous version of Windows. Click “Next” to continue.
Click the “Reset” button in the “Ready to reset this PC” interface. Your PC will reboot and begin to reinstall Windows 10.
Note: The “Reset this PC” feature on Windows is arguably the fastest way to reset your PC. There is a caveat: “Reset this PC” allows you to keep files only. The reset will uninstall all user-installed apps and programs. To avoid missing out on pre-existing apps, drivers and programs, make sure you have backups of all your important data before scheduling a reset.
