Windows 10: How Can I reinstall Win 10 Defender

I might uninstall Win 10 Defender accidentally. Although the Defender icon exists in the right bottom of my taskbars, it cannot be used to run quick scan or check for protection updates. A few days ago, I installed another anti-virus software--Sophos. But now, I uninstalled Sophs. How can I fix it? os and Defender went wrong.
