Just because they are running, doesn't necessarily mean anything is being installed. They also run when Windows Update checks for updates, either the daily automatic check or one you start yourself.

Updates that have been installed (if any) should be listed in Reliability History.

It got the 23H2 Feature Update on 4th November 2023 through Windows Update.

Yes, they keep the records about successful (or unsuccessful) updates, but not the log what they are doing right now. If you notice that Trusted Installer is working and consumes a lot of CPU, you can look which files are opened by this process in real time (if this helps). Run the Process Explorer as administrator, select the Trusted Installer and switch the screen to show the lower panel with the list of opened files, Registry keys etc.
