In Windows 10, you can change your wallpaper in the Settings app under Personalization>Background. It’s also a good idea to try a few different images in case the one you’re trying to set is corrupt. If it works, change it to a static image after. Instead of setting a static wallpaper, set a slideshow instead. If an app was the cause of the problem, disable it and try to change your wallpaper again. It will simply prevent it from happening again once you do fix it. Uninstalling the app won’t fix the problem. At the very least, disable it so that it is no longer controlling your display settings. If you installed a third-party app to modify your desktop or UI and the problem started right after, uninstall the app. Here’s how you can fix black desktop background in Windows.
