Just to add, since this update my cache is filled with a hundred or so thumbnails of the new lots and households I skimmed through from the Gallery and I am going to have to clear my cache every time I check it. I don't know if this is Windows 10 trying to be helpful (Prefetch style) or it is a fault with how the Gallery is presented.
When I checked the cache the day before the update there were just a few blurred household images in it (none of mine) even though I had looked at the Gallery several times. Seems a good way of spreading viruses as some are in code unreadable by any app. on my PC. 388 JPG, 1 .dat thumbnails, 5.5 MB approx.
