Accessing Security & Maintenance from Settings

I sometimes search for Security in the Settings app to find the option for Security & Maintenance. This no longer works in my admin account on my desktop PC running v1709. Nothing happens when I click on Security & Maintenance in the search box (see below) but it works fine in other accounts. I also think the gear wheel symbol is wrong.

sfc /scannow runs fine. Any ideas? I'm due to update this PC to v1803 - would that fix the issue since the update is basically a repair install?

Hello Steve,

That method is still working for me in build 18234.

Does running the shell command below open Security and Maintenance for you?

explorer shell:::{BB64F8A7-BEE7-4E1A-AB8D-7D8273F7FDB6}

Since posting I started maintenance manually and the Settings menu now works and displays the correct flag symbol instead of a gear wheel. Go figure. Yes the above command does work.
