hi,,,, as a rule i just have my security pinned to start up on 4 pc's,,, everything else you can start manualy when you want to use it by using the desktop short cuts or starting it from all programs,,, the 2 programs i have pinned are Avast and Superantispyware Full version,,,, everything works fine. A lot of the things on your start up are usally updaters for some of the software you have installed,,,ie ,, java, adobe etc,,, they will look for newer versions of what you have installed,,, you can stop all these because they will look for updates when you use the program's anyway,,,, if your unsure follow Johns excellant advice and you cant go wrong,,,,,, good luck.
