@jabbath1987 Alright !! Here's what you can do.If your system is making too many connections and you are no sure if its downloading content on its own,Close ALL browsers,all third party software's (If any) the you can open up the task manager->click on performance and observe Wi-Fi or Ethernet (Wired Connection) as shown in pics below.
You can easily see the difference between used and unused network activity.You can also click on Resource Monitor > Network to find out the connections made by your browser and the data being downloaded.
