I was wondering what was uploading to internet and decided to stop the services 1 by 1 to catch the culprit running under svchost.
I had stopped a few already that I thought were possible candidates, like windows update and the likes, but one of the remaining services was uploading to somewhere or other, can you determine which one from the image?
For me, I don't see what business any of those have uploading data to the internet, especially since I have every privacy setting and telemetry service I can find, turned off.
EDIT: I estimate it uploaded over 15MB of data before I stopped it.
