Getting Windows 10 to Use All Images in a Folder for the Background

Windows 10 lets you specify a folder for background images (Settings -> Personalisation -> Background menu), but by default it will only use the images in that base folder. If you have other folders in there in which there are other images, they won’t get included.

You can trick Windows into loading a bunch of images including those in subfolders:

1. Open the parent folder containing your images & subfolders
2. In the Windows search field, type in kind:=picture
3. This will do a magic Windows search looking for all pictures
4. In the list of images that come up, select them all (CTRL-A), right click, and set as background.
5. If you close and reopen the Settings dialog, you’ll see the the album name has changed and now looks like this:
   
   
   
6. You should now be able to right click the desktop background, select ‘Next desktop background’, and have it pick a new images.

I’m not sure what else this kind: operator can do in the search field but it seems like the kind of thing that would be handy.
