Did you ever get Windows Defender up & running , Ron? I fixed it by reverting back to Windows 7, running the McAfee removal tool, uninstalling MSE, then upgrading to Windows 10 again. Every thing seems to work right now. Thanks for your help. You're welcome!

That shows updates failed but it doesn't show any of the codes.

I have multiple errors everytime i try to update when restarting i just took a picture to make is easier https://gyazo.com/00f94e2446f864c08a784c32562442c3
