by default windows runs a bunch of bull crap, compensating for every posible pc setup, so it leaves ton's enabled/running.
EDIT: o yea heres a quick tip if u wont the menue lists to popup almost instantly(instead of waiting half a sec)
/HKey_current_user/control panel/desktop... 'MenuShowDelay' modify it to a value of either or between (0 to 100)
EDIT AGAIN: sorry, note- registry changes do not take efect untill u restart.
