Service Host Using over 30% Cpu

Just recently, I've noticed a couple of processes that run at over 30% cpu useage at idle. [Here](https://imgur.com/a/v70Vj) is what I am talking about. How can I bring this down? It's really limiting my computer when I play games or do other tasks. It persists after a restart. Did a recent update turn Internet Connection Sharing on because I haven't used it before and haven't seen it.

Edit: I also wanted to mention that when I restart/shutdown my computer, when it turns back on anything that was running will start again. This should NOT be happening. I want a fresh boot every time.

Update: I found the fix thanks to [this](https://www.reddit.com/r/Windows10/comments/7orbqq/service_host_using_over_30_cpu/dsbv5kw/) post. Just reset firewall settings.
