go to run, type msconfig, then click on startup and disable the junk you do not need and do the same with the services tab (make sure you click on "hide all microsoft services" first) this causes it to not start up when you boot anymore, then just knock it out for good with a clean roundhouse kick to the program files (registry - type regedit on the run console - if you are chuck norris)
HII BIGAPL!!!
