Set Personalize your background to Picture, select the desired image, and then ensure that no contrast theme is overriding it with a black background.
Set one permanent background picture
- Right-click an empty area of the desktop and select Personalize.
- Select Background.
- Under Personalize your background, choose Picture—not Slideshow or Windows spotlight.
- Select the picture under Recent images, or select Browse photos and choose the file.
- Optionally select Fill under Choose a fit for your desktop image.
The Picture setting uses one image, while Slideshow and Windows spotlight change images automatically. You can also right-click the image file and select Set as desktop background.^1^
Stop the black-background override
Because the icons remain visible, this is a desktop-background problem rather than the whole display turning off. Check the Windows contrast setting:
- Press Windows key + I.
- Go to Accessibility > Contrast themes.
- Set Contrast themes to None.
- Select Apply.^2^
Next, refresh the desktop:
- Press Ctrl + Shift + Esc to open Task Manager.
- Find Windows Explorer under Processes.
- Right-click it and select Restart.
The taskbar and desktop may disappear briefly and then reload.^3^
If the picture still changes after a few minutes
- Reset the active theme: Open Settings > Personalization > Themes, select a default Windows theme, and then return to Background and choose the picture again. Windows themes include background settings and can be saved after customization.^4^
- Check for wallpaper software: Open Settings > Apps > Installed apps. If Bing Wallpaper or another wallpaper-changing application is installed, disable or uninstall it before setting the picture again.^5^
- Install current Windows updates: Go to Settings > Windows Update > Check for updates, install everything available, and restart. This is especially important if the problem began after the August 27, 2026 update: Microsoft documented an issue that caused some desktop backgrounds to become solid black and resolved it in updates released on or after September 8, 2026.^6^
