Click Start> Control Panel> Administrative Tools. Look for "Services." Double Click Services. Scroll down in services until you get to Windows Defender. Right Click on Windows Defender and left click properties when the box opens up. Click on General. At the middle of the page you will see Start Up type. Set it to automatic. Below that is service status. Hit Start. click apply on the bottom of the window and then exit out. Reboot. It should start up. If it doesn't let me know what happens.
