Show hidden icons chevron missing some individual icons…

Dalchina -thanks for your reply
>>> I believe you're referring to the Windows Defender Notification Tray Icon<<<

I’ve had a look in Task Manager – Start Up but it’s not just disabled – its not listed…
I’ve followed the various ways that your link suggests to re-enable it – but I can never find it listed…

The Windows Security Notification icon is there and is enabled.

Thanks again.
