Sorry if this is a common topic. I'm new and searched, but perhaps didn't hit the right keyword.
I get a situation once every few days where my Win10 gaming box is hogging my WAN connection with no obvious reason.
Task Manager performance tab shows the ethernet traffic spiking the WAN downlink (10mbit, I'm in the boonies on DSL) and using a good portion of the 1mbit uplink too.
Task Manager processes tab shows no processes using the network to a measurable degree.
My router is showing my PC flooding the link (router graph is where I spot the problem first, usually.)
One time I traced the traffic to a random Level 3 IP in the middle of Kansas. I blocked that IP at the host Windows firewall and was trouble free for a few days. Then I got the same symptoms last week and didn't get a trace running on the router in time (duration is usually several minutes.)
So, all that is to ask this: Is there a 3rd party tool to run in Win10 desktop to see what services/processes are using the network *other* than the Task Mgr Processes tab? (again, the processes tab doesn't show anything using network during these bursts, though the performance tab does show the traffic on the ethernet port.)
