The fastest way to change your desktop background

Right-click on any empty space on your desktop — not on an icon or the taskbar — and select Personalize from the menu that appears. Windows will open the Settings app to the Background page. From there, you can choose a solid color, a picture, or a slideshow of pictures. Pick what you want, and it takes effect when ready.

If you have a picture file you want to use, you can also right-click the image file itself (in File Explorer or on your computer) and select Set as desktop background. This skips the Settings app entirely and sets the image in one step.

Key Takeaways

  • Right-click an empty spot on your desktop and select Personalize to open the background settings in Windows Settings.
  • You can choose from Windows' built-in pictures, upload your own image files, use a solid color, or create a slideshow that changes automatically.
  • Right-clicking an image file directly and selecting "Set as desktop background" is the quickest method if you already know which picture you want.
  • Windows stores your background choice and remembers it even after you restart your computer.

Using Windows Settings to pick a background

Open Settings by right-clicking the desktop and selecting Personalize, or by pressing the Windows key and typing "Settings" and pressing Enter. Once Settings opens, click Personalization in the left sidebar, then Background.

At the top of the Background page, you will see a dropdown menu that says Personalize your background. Click it and choose one of three options: Picture, Solid color, or Slideshow. Each option has its own settings below.

If you choose Picture, Windows shows you a gallery of built-in images. Scroll through and click the one you want. If none of those appeal to you, click Browse to navigate to a folder on your computer where your own photos are stored. Select the image and it becomes your background.

Setting up a slideshow that changes automatically

A slideshow background rotates through multiple pictures at an interval you choose. To set one up, open Settings, go to Personalization > Background, and select Slideshow from the dropdown.

Click Browse to choose which folder contains the pictures you want to cycle through. Windows will use every image in that folder. Below that, you will see Change picture every with a time option — the default is 30 minutes, but you can change it to 1 minute, 10 minutes, 1 hour, or 1 day.

You can also check the box for Shuffle if you want the pictures to appear in random order rather than alphabetically. Once you have set these options, the slideshow starts when ready and continues even when your computer is locked.

Using a solid color instead of a picture

If you prefer a plain background, select Solid color from the dropdown in the Background settings. Windows shows you a row of preset colors — black, white, blue, red, and others. Click the one you want and it applies right away.

If you want a color that is not in the preset row, click the + button to open a color picker. You can select any color by clicking on the gradient, or you can enter the exact color code if you know it. Once you confirm your choice, that color becomes your background.

Changing the background on multiple monitors

If you have more than one monitor connected to your computer, you can set a different background on each one. Open Settings, go to Personalization > Background, and select your picture or color as usual. Then scroll down to find Choose a fit — this controls how the image scales to fill your screen.

To set different images on different monitors, you will need to right-click each monitor's desktop separately and personalize it individually. Windows does not have a built-in way to assign different images to different monitors from a single settings page, so you repeat the process for each screen.

Troubleshooting when your background will not change

If you change the background but it reverts to the old one after restart, a group policy or domain setting may be preventing changes. This is common on work computers. Contact your IT department or system administrator — they may have locked the background setting intentionally.

If you are on a personal computer and the background still will not change, try restarting Windows. Sometimes the display driver needs to refresh. You can also try selecting a different image first, then going back to the one you want — this can clear a stuck setting.

If the image you are trying to use is very large (over 100 MB), Windows may have trouble loading it. Try using an image editor or an online tool to resize the file to a smaller size before setting it as your background.

Frequently Asked Questions

Can I use a video or animated GIF as my desktop background?

Windows does not natively support video or animated GIF files as desktop backgrounds. You can only use static image files like JPG, PNG, or BMP. If you want an animated background, you will need to read a third-party app from the Microsoft Store, though these can use more battery power and system resources.

Where does Windows store my background image?

Windows copies your background image to a hidden folder at C:\Users\[YourUsername]\AppData\Roaming\Microsoft\Windows\Themes. You do not need to access this folder to change your background — Settings handles it automatically. The original image file stays wherever you stored it.

Will changing my background affect my computer's performance?

No. A static background uses almost no system resources. A slideshow uses slightly more because Windows has to load and display new images, but the impact is negligible on modern computers. Very large image files (over 100 MB) may cause a slight delay when Windows loads them, but this is rare.

Can I set a background that spans across two monitors?

Not through the standard Windows Settings. If you want a single image to stretch across both screens, you will need a third-party tool like DisplayFusion or UltraMon. These apps let you assign a single background to multiple monitors as if they were one large screen.

What image formats does Windows accept for backgrounds?

Windows accepts JPG, PNG, BMP, GIF (static only), TIFF, and WEBP files. JPG and PNG are the most common and work reliably. If you have an image in a different format, you can convert it using free online tools or image editors like Paint or Photoshop before setting it as your background.
