My daughter's Toshiba laptop has become slower at start-up over the past three years, and CCleaner reveals many apps.in the 'start-up' list, which I believe slow it down. Is there any way of knowing which ones are essential to leave enabled in this list? I presume, if they are all dis-abled, the laptop will not start at all, or only in safe-mode. Any advice would be much appreciated, thank you.
