Factory reset of v2 hub does not remove previously downloaded drivers?

Does the v2 hub come with drivers already installed?

I did a factory reset and I see drivers for sonos, Aqara Presence Sensor, sonos, bose, phillips hue, etc

That is normal. There are some drivers installed but not loaded not running. If i find the thread, i will post it.

It started with Wemo and the list has been growing: Why SmartThings has Installed Unnecessary Wemo etc Drivers to my Hubs

You also can’t remove them… they will simply return within 24 hours.
