KB3065988, I would suggest hiding it, I certainly have hiden it on both my machines. It's very similar in what it does to KB3075853, there are loads of updates in the past few months which have come out as updates for the windows update client, I strongly suspect but am not 100% sure that the purpose of all these rceent updates to the windows update client is to give it the capability to download windows 10. It's not that, as far as I know, these updates to windows update client CAUSE background downloading of wndows 10, but without them I don't think it is POSSIBLE. If some day in the future it turns out that updates like this are actually useful and doing something good you could install them then, but it's easiest for now not to install this update because were you to want that update some day in future it would be easier to install it then than it would be for you if you installed it now then realised some day in the future that you didn't want this update.
P.S. this update MIGHT be listed in my "windows updates monitoring thread" as one to be cautious of, or it might not be mentioned at all. One thing you could do to check for information about updates is to look through that thread using your browser's "search the text on this page" function to look for the numebr of the update you want to know more about, because if it's one I mention somewhere in the thread (if I do mention it then the post will be within a week or so of the release date) you'll quickly be able to tell if an update is one which seems ok to me or one which is known to be problematic or one which sounds a bit concerning.
