For icons that that are already on or were used to be on your system tray, you can easily disable them from running (will no longer be visible in system tray as well) or reactivate them again by simply type in MSCONFIG in the RUN command (from Start Button). Choose STARTUP tab, and check or uncheck all the program you want to run. Beware, uncheck only the program that you are sure and that it will not cause any conflict to window starting up.

But for personal preference programs that you want to add directly to system tray, I'm not sure you can do for all the program. Some programs give you the option whether you want to add it to the system tray or not.
