To change background on PC, right-click an empty desktop area and choose "Personalize," or open Start > Settings > Personalization > Background. From there, pick a Picture, Solid Color, Slideshow, or Windows spotlight, and your new wallpaper applies instantly.
How to change background on PC: quick methods
The fastest way to change background on PC is to right-click an empty spot on your desktop and select "Personalize" (Windows 10/11), this opens the Background settings directly. Even quicker: in File Explorer, right-click any image file and choose "Set as desktop background" to apply it immediately without opening any settings window. On a Mac, Control-click an image in Safari and select "Use Image as Desktop Wallpaper," or Control-click a file in Finder and choose "Set Desktop Picture." If you want to bring that same personal touch to your TV, you can also change Roku background with custom images, and you can change your background on a tablet using similar touch-friendly steps.
Accessing personalization settings in Windows
For full control, navigate to Settings > Personalization > Background on both Windows 10 and Windows 11. The right-click desktop shortcut ("Personalize") takes you to the same place, saving you a couple of clicks. Once there, you'll see all background options in one panel, no need to hunt through submenus.
Choosing a background type: picture, solid color, slideshow, or Windows spotlight
Windows gives you four main background types, each serving a different purpose. Picture sets a single static image; Solid Color fills the screen with one uniform hue; Slideshow rotates through images from a folder you choose; and Windows spotlight automatically downloads and displays a fresh daily image from Microsoft, ideal if you want variety without manual effort. Pick whichever matches your mood or workflow.
Setting a custom image as your background
To use your own photo, select "Picture" under "Personalize your background," then click "Browse photos" (Windows 11) or "Browse" (Windows 10) to locate the file on your device. Windows supports common formats like JPG, PNG, and BMP. For an even faster route, right-click the image file in File Explorer and choose "Set as desktop background", this bypasses settings entirely and applies the image immediately. If you want a similar custom look inside your browser, you can also put your own picture on Google Chrome background.
Adjusting background fit and position
After setting an image, you can fine-tune how it appears on screen using the "Choose a fit" dropdown. Fill covers the entire screen but may crop edges; Fit scales the image to fit without cropping, leaving letterbox bars if aspect ratios differ; Stretch forces the image to fill the screen, potentially distorting it; Tile repeats the image in a grid pattern; Center places the image at its original size in the middle; and Span stretches the image across multiple monitors as one continuous picture. Use Fill for photos you want to fully cover the screen, Fit for preserving the original composition, or Tile for a subtle repeating pattern.
Using a slideshow background
For a dynamic desktop, choose "Slideshow" under Background settings, click "Add a folder," and select the folder containing your images. Windows will cycle through them automatically. You can set the "Change picture every" interval (e.g., every minute, hour, or day) and toggle "Shuffle" to randomize the order. This is perfect for showcasing a rotating collection of personal photos or artwork without manual switching.
Setting backgrounds for multiple monitors and virtual desktops
If you use multiple displays, Windows lets you assign a different image to each monitor. Under "Picture" background, right-click the image preview and choose "Set for monitor 1," "Set for monitor 2," etc., or select "Span" to stretch one image across all screens.
Changing background on a Mac
On macOS (Ventura or later), open the Apple menu > System Settings > Wallpaper. You'll find categories like Dynamic Wallpapers (which shift colors based on time of day), Aerials (animated screen savers that play on lock/unlock), Colors (solid shades), and Shuffle Aerials for random motion. To use your own photo, scroll to "Your Photos," click "Add Photo" or "Add Folder or Album," and select the image. For a quick shortcut, Control-click any image in Safari and choose "Use Image as Desktop Wallpaper," or Control-click a file in Finder and select "Set Desktop Picture."
Troubleshooting background issues
If a solid color background on Windows 10 doesn't persist after restarting, first check that "Show desktop background image" is turned On under Settings > Ease of Access > Display. Next, clear the cached wallpaper file by deleting "TranscodedWallpaper" in `%AppData%\Microsoft\Windows\Themes`, this forces Windows to regenerate the background. Finally, temporarily turn off "Theme" sync under Settings > Accounts > Sync your settings, as syncing can overwrite your local choice. These three fixes resolve the vast majority of background persistence issues.
