Good Morning, I have Vista Home Premium

[Vistainfo]

I stumbled across this website while searching for the best way to reduce the items in my start up menu, with the intent of reducing my boot time and increase computer efficiency.

Questions?

Does anyone know whether it is better to delete the item or disable it?

I've downloaded a number of sw applications and noticed that they are also in the start up menu, when if asked during download I usually deny. Is the placement in the start up menu autimatic, and something I should repeatedly check?

Thank you,
