I need help. My computer has started getting a little laggy. I want to maybe delete some programs to see if that will help, but when I look at the list of programs...I'm befuddled. I don't know what most of these are, what they do, or if they're important.

What the hell is WinRAR achiever? Do I need the Toshiba Quality Application? What is RICOH R5U230 Media Driver ver.2.02.02.01? WHAT ARE ALL THESE THINGS?

Should I just forget it?
