May I ask what usecase you have for running LibreOffice as administrator?

Well, the registry might cease to work any time, so I wouldn't
necessarily say it is not true based on that..

Also looks like that will be exposed in UI as well
https://www.windowslatest.com/2025/12/16/microsoft-confirms-you-can-soon-disable-smart-app-control-without-reinstalling-windows-11/
"Microsoft told Windows Latest that it made changes to the Smart
AppControl (SAC) to ensure “users can switch SAC off or on without any
clean install requirement based on feedback.” This change will roll
out in 2026, and it’s currently being tested in the Windows Insider
Program."

(also at least when SAC was introduced it was tied to sending
telemetry data - so in Europe at least you could deny/restrict that
when installing windows and limiting telemetry then also automatically
disabled SAC)
