I recently upgraded from W7 to W10 and overall am pretty happy. I have a twin monitor setup and as a professional photographer use a selection of my portfolio images as my screen background shots. With W7 I had the images change but they were the same image on both monitors. This was especially helpful as I could easily see that my monitors were calibrated the same.

It seems that with W10 you can choose images and do a slide show but for the life of me I can't see a way to sync the monitors to show the same image on both at the same time. I seem to have 2 slide shows going at once which I personally find visually distracting. My apologies if I am missing some simple setting.

I saw on one forum someone suggested a program called Johnís Background Switcher (or JBS for short) but I was hoping not to add yet another program.
