Good Day Ilias31,
My name is Carlo, I am also using Windows 10 pc and community member like you. Let us work together to sort this out.
The text in the /x2019s that would be more likely a visual bug, for the IT manager has limited aces to certain parts of this app.
Here's the steps you can try.
-Click Start, type CMD and run as administrator
-Copy and paste each of the command below and hit enter.
reg delete "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies" /f
reg delete "HKCU\Software\Microsoft\WindowsSelfHost" /f
reg delete "HKCU\Software\Policies" /f
reg delete "HKLM\Software\Microsoft\Policies" /f
reg delete "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies" /f
reg delete "HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsStore\WindowsUpdate" /f
reg delete "HKLM\Software\Microsoft\WindowsSelfHost" /f
reg delete "HKLM\Software\Policies" /f
reg delete "HKLM\Software\WOW6432Node\Microsoft\Policies" /f
reg delete "HKLM\Software\WOW6432Node\Microsoft\Windows\CurrentVersion\Policies" /f
reg delete "HKLM\Software\WOW6432Node\Microsoft\Windows\CurrentVersion\WindowsStore\WindowsUpdate" /f
Add-AppxPackage -Register -DisableDevelopmentMode "C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy\AppXManifest.xml"
If you getting errors when you enter each of the commands , it fine that's normal, just proceed with the next command.
Once you entered all those commands restart your computer and check if you will still see that notification.

Have a wonderful day ahead and stay safe.
