BTW, there's a neat new set of screen backgrounds for Win8 online with lots of new pictures, for those of you that, like me like scenery on your background.
To get to them, right-click on the background screen and select "personalize." On the screen that appears, you'll see in the box called "my themes" a couple of links, one of which is "get more themes online." Click that and your browser will take you to MS's site where you can download and install lots of themes.
Then on the bottom of that same "personalize" screen, you can click on "Desktop Background" and select which pictures to display, and if you want a slide show how often to change them.
Have fun!
