I'm curious. My install of Win10 on a clean SSD has two desktop themes with a Halloween motif. One is titled Eerie Autumn Modified and the other is the same theme but merely titled Unsaved Theme. If my memory is still functional I have had the Eerie Autumn theme installed on Windows 8 or 8.1. If I make any changes, such as the sounds (mail call) it will show the theme as Eerie Autumn Modified if I save it. Without saving it just shows it as Unsaved Theme. Did anyone else have these themes install with their Win 10 preview (right click on the desktop and select personalize)? They look like a theme I've had before and changed the sound (Radar O'Reilly announces Mail Call Sir). If it's just my install and these are themes that I had before where in heck did they come from? I have saved nothing in the cloud or anywhere else off the computer.
