way too many ive got 9 but the trick is to untick anything you DONT need when the pc starts up, for example on my pc i want my antivirus, firewall, msn etc to load up when i turn the pc on , but things like my graphics card control panel, limewire and stuff i dont want to use all the time so whats the point it letting it load up when i switch the pc on slowing it down? disable anything you dont want and then restart the pc, as a rule if your unsure what something is dont disable it, type it into google and it will tell you exactly what it is dont be frightened of disabling anything though as you cant screw up your pc or anything, at worst you just wont have a programme loaded up and you will have to click on the icon to start it manually, if you did disable something you didnt mean to then just go back onto the programmes options and set it to run on start up agian
