Like the title says, I am a bit new to formatting my own drives. In previous systems I have denied most of the windows stuff like firewalls, automatic updates and those kinds of things because I ran my own firewall and I updated when I saw there was an update. My question is, in order to maximize system efficiency what should I allow to run and what should I deny. From reading this forum I shouldn't allow WMP to automatically check for MP3 licencing which is pretty obvious, but what about the auto updates and firewall and the like?
