Something that I've always done is cruise the running processes, run a quick Google search on the process name to determine what it came from, and decide whether or not to disable it based on that information. You can also remove processes from your system's startup by typing "msconfig" in the start menu search bar and hitting enter. You'll find all of the applications set to launch on startup under the startup tab, and you can uncheck which ones you don't want to automatically launch.
