On Jan 24, 2023, W.U. downloaded and updated Windows security with this KB5007651 (Version 1.0.2301.24001).
After this update the security icon on the system tray showed a yellow warning triangle, and then the icon completely disappeared after a reboot.
No way to get the icon back on the System Tray. 🤷♂️
I can still open security if I search for it in settings, but there is no apparent reason for the shortcut on the system tray to be missing.
It looks like starting with Build 25272 the windows security updates are messed up and out of sync with the currently installed windows Build.
I could reproduce the same issue restoring a backup of Build 25281 and then going through W.U. checking for updates, the same scenario repeated again.
Right after the update shows yellow warning on security icon:
Everything green here, but Firewall & network protection is missing, that may be the reason for the yellow warning.

It look like this.

There isn't Defender icon in System tray and Firewall and betwork preotection is missing.
So this issue managed to messup also non-insider Win 11 Pro 22H2, build 22 and update to bulid 22621.1194 didn't fix this.
Hi Pauli,
Could you also check what you have in C:\Windows\System32\SecurityHealth?
Perhaps there could be some older updates installed by kb5007651 from 2022.
Now I get these KB5007651 and Defender version 25285 to non-insider Win 11 Pro 22H2 virtual machine.
Hi Pauli,
That looks messy, they screwed up 22621 before.
It all depends on if it is backward compatible.
Anything missing in the Security Dashboard?
Now I get these KB5007651 and Defender version 25285 to non-insider Win 11 Pro 22H2 virtual machine.
