Too many Processes in Windows Task Manager

Whenever I bring up the Windows Task Manager (by pressing Ctrl+Alt+Del), I find that there are way TOO many processes running. My computer is brand spanking new and it is already freezing to the point that nothing functions and I have to power if off manually. I don't like doing that, I think I'm damaging it further. I am attaching 3 screenshots of the Task Manager, yeah that's how many processes are open. Could anyone please have a look at it and tell me which of the processes are unnecessary, what they are and how can I prevent them from starting up whenever I switch on my computer. I am new to windows 8 and do not want to damage anything.

Thanks for all of your help in advance! :o
