Windows Defender Update Issue

[Guest]

I'm getting the following error message when I try to Check for Updates:

Windows Defender was unable to complete the update: 0x80244008

I've uninstalled and reinstalled. Same issue. Any thoughts?

If your windows update is pointing to your local WSUS, then you must include
the Windows Defender in synchronization setting.
In Products selection, please include Windows Defender
In Update classifications, please include Definition Updates

You must synchronize the server and approve the definition for clients to
get the latest definition.
