Windows 10: Why exactly is the Device Association Service needed?

So according to the description of the Device Association Service, it's purpose is:"Enables pairing between the system and wired or wireless devices."Okay, so even after I disable the service, all wired and wireless devices are still running fine. So why is this service needed at all? It never existed in Windows 7 or earlier, only seems to have been introduced with Windows 10 and 11.

:)

 

How can I find out what is triggering Device Association Service?

The service Device Association Service which Enables pairing between the system and wired or wireless devices.

This service is set as Manual (Trigger Start). Normally this service never started by itself during computer turn on or restart. But from recent few days I have noticed that this service runs in the background at all times on startup and doesn't go away.

Is there a way to find out exactly which device is triggering this service to start? Surely Device Association Service isn't meant to be running in the background at all times?

I have made sure to update all drivers, everything is up to date. This service isn't using CPU usage and the memory is very low, admittedly. But I still want to find out what is triggering this service to start! I know I can disable the service, but then I won't know what is trying to start it up.

 

Device Association Driver Service

Ok, in three sentences:
What "devices"?
In what does "association" consist?
Purpose of such "Device Association"?
