with 2.0 release it brings an advanced tab, it gives you control over intent receivers directly, so you can completely disable automatically running parts of applications
a few words from my home page
Autorun Manager (formerly Autorun Killer) lets you decide what apps you want to let automatically start up. It sports two modes:
Basic mode lets you decide which startup apps should be killed right after they start during system boot process.
Applications are usually autostarting because of a reason, so only disable one if you know exactly what it is doing and you definitely don't need it.
Advanced mode lists all your applications which are registered for system wide events (aka. intents like an incoming call, low battery or boot finished) and gives you the control to enable or disable these -so called- receivers.
Using this mode recommends above average knowledge about how your device works. Please be very careful.
