Now I see I misunderstood your question, at least by a bit. I'm not entirely sure what comes on a 2016 Dell, I will early next week when the one I just ordered arrives. From the packing list of my order I have already guessed that I would definitely remove the Office trial, McAffee AV. I would have to check out Cyberlink Media Suite Essentials to see what my dad thinks of it (the computer is for him), in the past I removed it I believe, because I didn't find myself using it...though it may have changed....some of the features were upgrades and I never used the free ones. In my previous experience though, I tended to consider anything that is trial-ware as something I would remove; there could be exceptions to that I suppose, but of course that would mean I would be willing to buy the software at the end of the trial and I've never had that happen.  I personally also remove any of the Dell utilities, though for my father I will likely leave the system update utility to update drivers. I tend to update the system myself on my own and prefer not having the process running. I also tend to get answers to my questions here on the forums, so I remove anything related to Dell service (I forget what they call it, but some utility that allows you to more easily connect with Dell if you are having a problem). If I remember I will come back and make a better list once I get my fathers desktop next Tuesday (or so). For me personally though, I honestly tend to reinstall the OS and the Dell drivers and not have any of their pre-installed software. Same with any company, not just Dell. I've never found anything useful, and what is put on there only slows down my system. But as the other poster mentioned, one man's bloatware is another man's treasure.  A friend says a good measure is to wait a month and whatever begins nagging you to pay for it (meaning it's trial ware) gets uninstalled unless he's willing to buy it, and anything he hasn't used by then even if free gets uninstalled if most cases too. He says if he's not going to use it by then he figures it's only slowing down his computer, especially if it's loaded at startup. 
Hi could someone please refer me to a FAQ or article with suggestions about removing unnecessary software from a new Laptop.  First to go will be McAfee - is there other stuff people recommend removing? TIA
