The Desktop Background Shuffle · 1:58am
This has nothing to do with fiction but it will help fellow Windows 10 users with their pile of pony pics they use for backgrounds. (I'm just past 1300 myself so it's pretty rare to see the same image twice in a week)
You may have noticed Win10 has a shuffle feature for backgrounds on the desktop, but it only seems to work with one default folder and won't go into any sub-directories. I have the fix.
First, use the Win10 [Personalize] feature as usual. I set it up to cycle every minute and "fit" the image. I also go into the "color" submenu so it picks colors to match the background image.
Once done, close that out and open a command prompt (right click on the Window logo in the bottom left, it's fastest)
At the prompt, enter:
control /name Microsoft.Personalization /page pageWallpaper
This gets you the old (hidden) Windows 7 style wallpaper selection screen. Just set it to what directories you want and you're golden.
You can then test it out by right-clicking on the desktop to select "next desktop background" to see if it picks from the right images. If you set it to select matching colors, the taskbar should also change color after a tiny delay.
Note: if you ever open the Personalize menu, by accident or not, you'll have to do this again as Windows resets the images to that default folder.
