How do I modify what program start at boot up?

[Astralogic]

Hi forum, I recently installed a few games which for some reason seem to start up in the background upon booting my tablet.

Can someone tell me how I go about changing the startup apps please?

Thanks

try downloeading android assistant app. There's a section for kill on startup and battery saver plus other useful tools. This may help.
