Formatting during Windows setup provides the most complete reset.

Windows blocks that process, so you must use setup or advanced startup.

You need a USB only for clean installation. Reset this PC works without it.
Formatting restores system stability and clears out problems that normal troubleshooting cannot fix. Choose the method that fits your situation and back up important files before you start.
