In a nut shell that computer a mess as far as im considered, way too much junk running and probably a bad case of malware going on with a side order of virus.
btw you see the big red bars in Security Task Manager, that from user option and you have piles in the 75+ hate range.
You should run as many anti-virus/rootkit/malware detectors as you can in that mess and uninstall useless trash as well as do the rounds with some win10 guides when it comes to turning off useless processes.
Basically your computer from the pics looks infested, that's why cpu use is high and why its running badly.
if you want you can take your posts over here if you want to spend a feu weeks letting a pro help you remove trash from the computer.
My self id just purge the hdd and reinstall.
