Looking for a Source for CallerId = Update;ScanForUpdatesForUser

Question

Hello,

I am aware of the process UpdateOrchestrator which is the Windows process that is used to Manage the Windows Updates.

However, while analyzing the below windows update log I found process Update;ScanForUpdatesForUser under CallerId which means this process is triggering Windows update to find patches.

I am trying to find which Source/Process is executing Update;ScanForUpdatesForUser, is this also one of the Windows processes? If yes then how can we confirm it?

What is the best way to identify sources for such CallerId in the future?

How we can stop Update;ScanForUpdatesForUser from downloading activity?
