End certain windows tasks?(or atleast make them use less recources)

I'm running Win10, and all my games are running a lot slower. Service local system has 3 tasks running, all using 5% of my cpu. Is there a way to disable them?

You might just need a better CPU man...

I got a FX 6300. I don't think i need to upgrade anytime soon.

In that case, the issue may not be those random processes. It maybe Windows 10 and the issues that have shown up from it like with the drivers and whatever. My brain is working too slow for me to recall exactly right now.
