how do you disable all the crap-ware on the nexus?

So I opened up a "task cleaner" and saw about a thousand open progs. closed them all, re-opened the task cleaner, same progs open again!


Is there a way to get rid of all that crap running in the background without rooting and flashing? I'd like to keep my girl's phone's warranty intact, but I would like her to be able to use some RAM for programs she actually opens...

and is there a way to CLOSE a program by hitting home key, without having top re-open a task manager and kill it?
