Nature thread please.

Also, if anybody can help: I have a three-monitor set-up, and with Windows 7, all monitors displayed the same wallpaper, with a rotation of 10 minutes. When I installed Windows 10, all my monitors have different wallpapers, and individually they rotate wallpapers every 10 minutes, meaning that I have the same wallpaper on each individual monitor for about 30 minutes. Anybody know how I can change this? I downloaded the registry setting to get Personalize (classic) on my options for personalization, but that doesn't seem to offer an option for this.
