I found Google Chrome running as service after I installed it, at each reboot. This would not be a problem, if it won't eath 100% cpu. I would not like to uninstall it, but I'll be forced to do that if I can't find a way to disable its remain in memory as a service.
I couldn't find anything in Boot-Up-Manager, so I'm asking where to search...
Do you have "Continue running background apps when Google Chrome is closed" ticked? If so, try unticking the box and then remove Google Chrome from the Startup Menu.
Also check to see if you have any sort of "notifications" such as GMail or messaging that may be causing the browser to be "always on".
I had cloud print enabled which caused it. Try disconnecting any cloud print printers you may be sharing from this computer. In vasa1's pic, if you're sharing any printers, under Google Cloud Print, instead of 'Add Printers' there will be a button for disconnecting printers. Hit that and then also make sure you have background apps unchecked (off).
Type this command s in terminal
And do a reboot , click the top Right-Corner Settings icon , to select Startup Applications.
If Google Chrome is present in list there , just Unselect to stop Autostarting it.
You do not need to go to terminal to do this. There is an app called Startup Applications, which you can find by pressing the 9 dots in the corner and typing "Startup". Then, if Google Chrome is selected, unselect it and click "remove". That's all! It should stop opening chrome every time you log in. ;D
