Just 1 hour ago after updating to the latest antimalware platform update, the Windows Security does not show up in the system tray after reboot or restart. I tried repairing Windows, creating a new account, repairing the app or resetting the app. I also enable the Windows security icon when downloading a reg file. Anyone else facing the issue? After restarting, the icon appears for a few seconds and then disappear completely. Should I send a feedback?
It is not just the antimalware update KB5007651 also changes the version of the Microsoft.SecHealthUI to 25285 and that seems to be incompatible with this Build and causing the problems.
There is an FBH report, see link below, just upvote it or open another one. The security updates are becoming a mess.
