Bluetooth, DejaDup, Ubuntu One... Startup issue

I have manually removed Bluetooth, Ubuntu One, and DejaDup from Zorin, even go in and manually remove them from the startup manager. However, when I use look changer or log off and back on the startup items are yet again in the Startup Manager Menu checked as if I had never touched them.. Even the Ubuntu One that I removed still continues to function in the right click menu even though the package manager shows it is not installed, how do I permanently remove these items from Zorin, and the Startup group?

start/Ubuntu software manager/ type in program you want to remove in search box click it then hit remove reboot may not be a bad idea as well

I tested it out on dejadup worked for me.

Oh that is exactly what I have tried doing, but I use look changer then log back on and there they all are again, I have ripped out Ubuntu One totally, or so I thought to still see the right menu link come back and it still show back up in the startup manager as if I had never removed them to begin with, there must be a default file/files that the look changer accesses that puts these links right back even if the programs are not installed is all I can figure, but what files would that be in is what I need to know...

/etc/xdg/autostart/
is where all the default startup items are, I removed what I didn't want and problem solved....
