Windows Defender Update error 0x80040111

[AngerEyes]

If I am trying to get Windows Defender to update then I am getting an error code: 0x80040111 and the popup in the right lower corner said that the program is not able to check for updates, even though the laptop that I have both run via the same hub, except the laptop is wireless. Any ideas? Thanks.

Have you tried to uninstall Defender and then go to Microsoft's web site to re-download it. This should fix the modules of the Defender.

You can try to contact Microsoft for support. I believe there is a no-charge support for Windows Update issues. Or you may want to try another Repair install then try the following article after the repair install.
