I also want to make clear that I am presuming a lot of the things shown in the original poster's Task Manager screen shot, e.g., the Steam Client processes, Hearthstone Deck Tracker, TeamSpeak 3 Client, are all being started up at start up rather than being fired up via specific user action.
It is amazing these days, at least to me, how many programs have "run in the background, beginning at system startup" features so that they will appear to start up faster if/when the user decides to use 'em. I always turn these features off. I know when I wish to use something and I'm very glad to take "the penalty" of a few extra seconds when I initially start that program rather than the penalty of it demanding system resources all the time, particularly for those things I use infrequently. All the things I use routinely, e.g., Firefox, Chrome, get fired up as soon as my system is booted and generally stay running until I reboot the system, which is often days and days later.
