How to best reduce CPU load by elininating processes in Windows 7

You don't want to do that. Suppose your antivirus is updating and using a lot of the CPU power - you want to let it update.
Before you kill anything, be sure you know what it is doing.

Install CCleaner

Run it and in the left pane, click on Tools. Then click on startup.
Down towards the bottom right you'll see a button "save to text file". Click it and post that file as an attachment to your next post. That will let us see what you have running when the computer starts.

I use WinPatrol to allow me to disable things that keep trying to run at startup (like an intel graphics icon near the clock).

Both CCleaner and WinPatrol are free. You can opt to pay for WinPatrol. BillP runs sales once in awhile and I managed to get a copy for 99¢ when he had a sale.

 

It will take me some time to research your entries and decide what can safely be disabled.

 

You have 10 items running at startup. Four of them can probably be disabled from loading at startup.
1. BitComet http://wiki.bitcomet.com/bitcomet_options stop BitComent from startung with Windows

2. Epson You can stop the Epson status monitor from running at startup

3. "AdobeARM.exe is a part of new Adobe Acrobat\Reader updater. If you manage updates yourself, it is absolutely safe to remove it from Run registry." I don't use Adobe Reader but if I did, I would not wnat it running to check for updates.

4. APSDaemon http://www.bleepingcomputer.com/startups/APSDaemon.exe-27028.html
How often do you sync your phone with the computer? If not daily, then it doesn't need to run at startup.
