From what I've read on the net, if you install them they turn your PC into an unusable heap of junk. Also, they seem to be only aimed at anyone that was eligible for the 'Free' Win10, but didn't take up the offer.
Neither Microsoft or Intel are giving any helpful information.
The consensus of opinion on the net generally is 'Don't Install' them...
