There is an overlapping but not identical selection of themes in the Microsoft Store, the store built into Windows 10 that you don’t use. They are indexed so you can easily browse through particular categories – animal photos, or panoramic photos that span dual monitors, for example. There is an aging but quite nice selection of themes that can be downloaded in a few seconds from this web page. I’ll tell you where to get the themes, and along the way, we’ll talk a little bit about the failure of the Microsoft Store. A typical theme rotates through ten or fifteen photos when you get bored, it’s easy to switch to another theme with new pictures. Microsoft has gorgeous collections of photos that you can use for free as your Windows wallpaper.
