Windows 10: Wallpaper keeps changing to black with sliver of original

Ever since a few days ago, my wallpaper has been randomly changing to this:it transitions as if it's on a slideshow mode but it's picture. When it does this, it stores it in my recent images too, despite I am not doing it, it happens at random.

Win-10 themes keep changing

Hi,

Thank you for providing the information.

• Did you try the steps suggested by Suvarna Govinda above, what was the result?

As I understand the issue, Themes in Windows doesn't have the options to change on its own. Only the Wallpapers in the themes can change as selected ( Picture, Solid color and Slide Show ).

I would suggest you to make us understand that if the Wallpapers are changing in Theme which you have selected.

Below are the steps you can check if it helps.

• Press Windows + I keys and select Personalization.
• Select Theme and select the Default theme.
• Select the Desktop Background below and select the Picture
  and save it and check.

Please post us back if the issue resolves. We are glad to help you.

 

Desktop Black Wallpaper Won't Change (Windows 10)

This same thing has happened to me, except I can change my theme and the accent colors around windows, taskbar, tiles, and smart menu also changes to reflect the theme and the desktop picture color, however for me, my actual wallpaper is not when I assigned
it, it is black. I can change to different themes fine, but the wallpaper does not change, I can assigned wallpapers manual via "set as wallpaper" but my desktop wallpaper does not change at all.... it remains black, I can swap to solid colors from the background
menu, but when I change to picture for a wallpaper it is black and no wallpaper is display, just black.

ALSO: I did a clean re-install hoping it would fix it, but no, it is not fixed which is breaking my mind..... A full reformat, re-install of windows 10 and the problem is persistent from the beginning? is this a Microsoft account error problem of some sort??
