Trying to solve an issue similar to the one answered here after an upgrade from Win10 Pro to Win11 Pro:

https://answers.microsoft.com/en-us/windows/forum/all/windows-update-showing-windows-intelligence-update/d36cb4f1-22a1-43fa-be0b-d07974a37628?page=1

Tried everything in that thread and also uninstalled Webroot AV, but problem persists.

Went to Windows Security > Virus & threat protection > Virus & threat protection updates. Said Security intelligence is up to date. Clicked "Protection updates" then "Check for updates" and got the given error with "A security error occurred".

How can I find out what object is causing the problem?

Thanks,

Dave

    Hello Saeid,

    I checked the system date & time.

    I can't check for updates as the button is missing.

    No problem with Internet connection.

    Have uninstalled 3rd party AV.

    Dave
