The simplest method to close these programs, should be to click on
each from the taskbar -
saving anything which hasn't been ...
then later they open right back up
[mere seconds ]
BTW - I don't know what Apple-Mobile is, but ITunes - as well as
other programs which happen to get into the start-up menu - can be removed
by clearing that and/or going into their individual properties/options and
re-setting that aspect -
when these programs are installed, they'll ask whether you want
short-cuts and where these should be -
[I always refuse the option to add to the start-up menu ;-)]
