The method to apply window wallpaper depends on the operating system you're using. Since the reference mentions Windows 10, this answer will focus on that OS.
Here's how to change the desktop wallpaper in Windows 10:
-
Right-click on any empty space on your desktop.
-
Select "Personalize" from the context menu. This opens the "Settings" app to the "Background" settings.
-
In the "Background" dropdown menu, choose one of the following options:
- Picture: Select a single image from your computer to use as your wallpaper.
- Solid color: Choose a solid color for your background. You can select from pre-defined colors or select a custom color by clicking the plus (+) icon.
- Slideshow: Select a folder containing multiple images. Windows will then cycle through these images, changing the wallpaper at a set interval.
-
If you selected "Picture," click the "Browse" button to locate and select the desired image from your computer.
-
If you selected "Slideshow," click the "Browse" button to choose the folder containing the images you want to use for the slideshow. You can also configure the slideshow interval (how often the wallpaper changes).
-
Choose a "Choose a fit" option. This determines how the selected image is displayed on your screen. Options include Fill, Fit, Stretch, Tile, and Center. "Fill" and "Fit" are usually the best choices for most images, as they try to avoid distortion.
