Win 8.1 help tips popup if Microsoft thinks you might need them and won’t – yes will not – go away unless you follow the help tips directions, whether you want to invoke that function or not.
Here’s the URL to a Microsoft article to permanently disable all popup Win 8.1 help tips, if they are annoying you or you are on a non-touch display where the tips have very little value.
Additionally, if you just want to make one disappear – and not permanently disable all help tips – follow the help tips instruction (you can do this with touch or a mouse) and then it will go away and that particular tip should not come back anytime soon. Microsoft should just put an X on it to close these annoying little pieces of stuff… duh.
Hope this helps, Mike
