Change the Desktop Background in Windows 11 and 10: Pictures, Slideshows, Spotlight and Every Fix

To change the desktop background in Windows 11, right-click an empty part of the desktop, choose Personalize, then Background. Under Personalize your background, pick Picture and select one of the recent images or Browse photos, Solid color, Slideshow to rotate through a folder of pictures, or Windows spotlight for a new photo every day. Under Choose a fit, Fill suits most photos. The fastest route of all is to right-click any picture in File Explorer and choose Set as desktop background. In Windows 10, the same page is Settings, Personalization, Background. If the options are grayed out, Windows is not activated or a work policy is in control, and if the background keeps changing by itself, a slideshow, Spotlight, theme sync or a work policy is usually the reason, all covered below.

Ethan's father had been staring at the same blue Windows swirl for three years, convinced that changing it meant "going into the system". When Ethan finally sat beside him and changed it to a photo of the grandchildren in under a minute, his father wanted the whole album. Jake, hearing the story, suggested the setting that turned out to matter most: a slideshow of a folder of family photos that changes every hour, with Fill so nothing was stretched. Two weeks later came the inevitable call. The background had "gone black" by itself. Ethan found that Windows had been deactivated after a motherboard repair, which grays out personalization, and once activation was sorted, the grandchildren came back. This page covers every way to change the desktop background in Windows 11 and 10, slideshows, Spotlight, colors and multiple monitors, plus every reason the background will not change, keeps changing or goes black, and the settings that stop it happening again.

Change the desktop background in Windows 11

Windows 11 puts every background option on one Settings page, and you can reach it from the desktop itself.

1. Right-click an empty area of the desktop and choose Personalize. Or open Settings with Windows + I and select Personalization.
2. Select Background.
3. Next to Personalize your background, choose Picture.
4. Select one of the Recent images, or select Browse photos, find your picture, and select Choose picture.
5. Under Choose a fit for your desktop image, pick Fill for most photos; the fit options are explained below.

The change applies instantly, with no Save button. The Recent images row keeps your last few choices so you can switch back quickly. Windows 11 also includes a set of default wallpapers, which appear in Recent images on a new PC and can be found again in the Themes page by choosing a Windows theme.

If you prefer no picture at all, choose Solid color and pick a color, or select View colors for a custom one. A plain, calm color makes desktop icons easiest to read, which is why it is a common choice for work PCs and for people with tired eyes.

Where to find good wallpapers

The best source is your own photos, but there are safe places for more. Windows itself includes a set of wallpapers in C:\Windows\Web\Wallpaper, with the default pictures and the themed collections, and Windows spotlight supplies a new photo daily. The Microsoft Store's free themes bring curated photo collections, as our themes guide explains. Many camera makers, space agencies and museums publish free high-resolution images, and photo communities often let photographers share wallpapers under clear terms.

Whatever the source, take the picture file only. Sites that ask you to install a wallpaper app, a browser extension or a "wallpaper manager" to get an image are the ones to avoid. Check the file's size too: a wallpaper for a 4K monitor should be at least 3840 by 2160 pixels, which File Explorer shows in the Details pane when a picture is selected.

Change the desktop background in Windows 10

Windows 10's page is laid out slightly differently but offers the same choices. Right-click the desktop, choose Personalize, and the Background page opens. In the Background list, choose Picture, Solid color or Slideshow, select a picture or Browse for one, and set Choose a fit. Windows spotlight for the desktop is not offered in Windows 10's Background list; it is a lock screen option there, as explained in the Spotlight section below.

Windows 10 is past its October 2025 end of support except for PCs enrolled in Extended Security Updates, but personalization has not changed, so everything on this page applies to it, including the fixes.

The one-click way: Set as desktop background

You do not need Settings at all for a single picture. Open File Explorer, find the picture, right-click it, and choose Set as desktop background. In Windows 11, the option is in the first right-click menu; if you do not see it, select Show more options. The picture becomes the background immediately, using the fit setting currently selected in Settings.

This works for any picture file Windows can display, including JPG, PNG, BMP and HEIC photos from phones, once the HEIF image extension is installed from the Microsoft Store. It also works from the Photos app: open a picture, select the three dots, and choose Set as, then Background. Selecting several pictures in File Explorer and choosing Set as desktop background starts a slideshow of just those pictures, which is a quick way to try the slideshow feature.

Pictures downloaded from the web also work this way, saved first to your Pictures folder. Be careful with wallpaper download sites: the picture file itself is harmless, but sites that offer an installer or "wallpaper app" download instead of a plain image are a common source of adware, as our guide to downloading themes explains.

Using photos from your phone

Most people's favorite pictures live on a phone. The quickest route to the desktop is to copy them to the PC: connect the phone with a cable and copy from its DCIM folder, use the Phone Link app's photo view on Windows 11, or let a cloud service such as OneDrive, Google Photos or iCloud Photos sync them to a folder on the PC. Once the pictures are in a folder on the PC, right-click one and choose Set as desktop background, or point a slideshow at the folder.

iPhone photos arrive as HEIC files, which Windows can display and use as wallpaper once the free HEIF Image Extensions package is installed from the Microsoft Store; without it, HEIC pictures show as blank icons and cannot be set as backgrounds. Phones also take portrait pictures, which look best with the Fit option and a dark background color, or cropped to landscape first in the Photos app.

For a slideshow that updates itself with new family photos, point it at a cloud-synced folder that other family members add to, and set the folder to Always keep on this device so the pictures are downloaded for the slideshow to use.

Fill, Fit, Stretch, Tile, Center, Span: which to choose

The fit setting decides what happens when a picture's shape does not match your screen, which is nearly always. This table explains each option.

With Fit and Center, the color around the picture comes from the Choose your background color option that appears beneath the fit setting. A dark color makes photos look framed; matching the picture's dominant color makes the bars almost disappear. For a sharp result, use a picture at least as large as your screen's resolution, shown in Settings, System, Display; a 1920 by 1080 photo looks soft on a 4K monitor. Our guide to screen resolution and scaling explains how to find and change it.

Match the picture to your screen

Blurry or soft-looking wallpaper is almost always a picture smaller than the screen. Find your screen's resolution in Settings, System, Display, under Display resolution, and compare it with the picture's dimensions in File Explorer's Details pane. A picture with more pixels than the screen is always fine, since Windows scales it down cleanly; a picture with fewer pixels is stretched and loses sharpness, especially noticeable on text and edges.

Shape matters as well as size. Most laptops and monitors are 16:9 or 16:10, so a photo straight from a phone camera, usually 4:3 or 3:2, will be cropped at the top and bottom with Fill. If something important sits near the top or bottom of a photo, crop it yourself to 16:9 in the Photos app first, using the crop tool's aspect ratio option, and then set it as the background so you control what is cut.

Set up a slideshow of your own photos

A slideshow changes the background automatically from a folder of pictures, which is what finally made Ethan's father love his PC.

1. Put the pictures you want in one folder, for example Pictures\Family. Only pictures in that folder, not subfolders, are used.
2. Open Settings, Personalization, Background.
3. Set Personalize your background to Slideshow.
4. Select Browse next to the album and choose your folder.
5. Set Change picture every to 1 minute, 10 minutes, 30 minutes, 1 hour, 6 hours or 1 day.
6. Turn on Shuffle the picture order if you want a random order, and choose a fit.

Two settings matter on laptops. Let slideshow run even if I'm on battery power is off by default, so the picture stops changing when the laptop is unplugged, which is a common reason a slideshow "stops working". And if the slideshow folder is on OneDrive and the pictures are online-only, Windows may skip them; right-click the folder in File Explorer and choose Always keep on this device. To skip to the next picture at any time, right-click the desktop and choose Next desktop background.

A slideshow uses almost no resources, since Windows loads a new picture only when it changes. Very large photo folders are fine, but photos with mixed shapes look better with the Fit option and a dark background color, so portrait and landscape shots both look intentional.

Slideshow not working: every cause

When a slideshow stays on one picture, the causes are the ones that stop any wallpaper changing, plus a few of its own. The laptop is on battery and the battery option is off, the most common reason by far. The folder has only one picture Windows can read, because the rest are in subfolders, which slideshows ignore, or in a format Windows cannot display. The folder is on OneDrive with online-only files, so Windows finds nothing to show. The interval is set to 1 day, so it is working and simply slow; right-click the desktop and choose Next desktop background to prove it. Or the PC sleeps before the interval passes, so the picture only changes when the PC has been awake long enough.

Power plan settings can also pause the slideshow: in Control Panel, Power Options, Change plan settings, Change advanced power settings, under Desktop background settings, Slide show should be Available, not Paused, for the plan in use. That setting is easy to flip by accident while adjusting other power options, and it is the first thing to check when the battery switch is already on.

Windows spotlight: a new photo every day

In Windows 11, Windows spotlight puts a different high-quality photo on the desktop each day, with a small icon in the corner that tells you where it was taken and offers to show more like it. Set Personalize your background to Windows spotlight and it starts working within a few minutes, once the first picture downloads. Right-click the icon, or the desktop, for options to switch to the next picture or say whether you like it.

Spotlight needs an internet connection to fetch pictures, and it is not available on some work PCs where IT turns it off. In Windows 10, Spotlight is a lock screen option rather than a desktop one; our guide to Windows Spotlight as wallpaper shows how to save Spotlight pictures and use them as desktop backgrounds on either version.

Save a Spotlight picture you like

Spotlight pictures are stored temporarily and replaced each day, so a picture you love can vanish. On Windows 11, right-click the Spotlight icon on the desktop and look for an option to learn more about the picture, which opens a Bing page where the image can usually be found; to keep the actual file, copy it from the Spotlight cache before it is replaced. The cache lives under %LocalAppData%\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets, where the files have no extensions; copy the large ones to your Pictures folder and add .jpg to their names. Our Spotlight guide walks through this step by step. Saved Spotlight pictures then work like any photo, in a slideshow or as a single background.

Different backgrounds on two or more monitors

With several monitors, Windows uses the same picture on each by default, or different pictures from a slideshow. To put a specific picture on a specific screen, open Settings, Personalization, Background, make sure Picture is selected, then right-click one of the Recent images and choose Set for monitor 1, Set for monitor 2, and so on. To find out which monitor is which, use Identify in Settings, System, Display.

For one panoramic picture across all screens, choose Span under Choose a fit; this works best when the picture's shape matches the combined screens, for example a 3840 by 1080 image for two 1920 by 1080 monitors side by side. If a monitor shows the wrong picture after docking or undocking a laptop, the monitor numbering changed; set the pictures again, or use a slideshow, which does not care which screen is which.

Laptops that dock to a monitor

A laptop that is sometimes used alone and sometimes on a desk with a monitor effectively has two desktop layouts, and the wallpaper fit that looks right on a 16:10 laptop screen may crop awkwardly on a wide monitor. A slideshow with Fill handles both reasonably; a single picture with Fit and a matching background color avoids odd crops. If you set different pictures per monitor and they swap after docking, the monitor numbers changed; Identify in Display settings shows the current numbering, and setting your preferred screen as the main display keeps the arrangement steadier.

Background color, accent color and dark mode

The background is one part of the desktop's look. In Personalization, Colors, choose Light or Dark mode, and set the Accent color to Automatic so Windows picks a color from your wallpaper, or to a fixed color. Dark mode with a dark wallpaper is easier on the eyes at night, while a light wallpaper and light mode suit bright rooms. Our guides to dark mode and taskbar, Start and accent colors cover the options.

Once the background and colors suit you, save them as a theme: in Personalization, Themes, select Save and name it. You can then switch between your own themes and Windows' built-in ones with one click, and restore your look if anything resets it.

Themes: your background, colors and sounds in one click

Themes bundle the background, accent color, light or dark mode, sounds and mouse pointer, so you can switch the whole look at once. Windows 11 ships with several, in Personalization, Themes, including light and dark versions of the default look and several photo collections, and the Microsoft Store offers many more free themes with their own wallpaper sets. Choosing a theme replaces your background with the theme's pictures, which is one more answer to "why did my background change": someone picked a theme.

Your own settings appear on the Themes page as Custom until you save them; saving a theme is also the easiest backup of a wallpaper slideshow setup, since reapplying the theme restores the folder, interval and fit together. Our themes guide covers downloading, making and sharing them.

If a theme you downloaded changed more than you expected, such as sounds or the mouse pointer, open Personalization, Themes, select your saved theme or one of the Windows themes to put everything back at once, then change just the background again.

The lock screen and sign-in screen are separate

Changing the desktop background does not change the picture you see before signing in. The lock screen has its own setting in Personalization, Lock screen, with the same choices of Windows spotlight, Picture or Slideshow, plus a switch for showing the lock screen picture on the sign-in screen too. Many people set both to the same photo or folder for a consistent look. Our guide to the lock screen slideshow covers its quirks.

One difference catches people out: if the lock screen is set to Windows spotlight, it may also show tips and fun facts on the sign-in picture, controlled by a separate switch on the same page. And on work PCs, the lock screen image is often fixed by policy while the desktop remains yours to change, which is why the two can look so different on the same laptop.

Background settings grayed out or "disabled by administrator"

If the Background page shows its options in gray, with a message near the top, one of two things is true.

Windows is not activated. The page says something like "You need to activate Windows before you can personalize your PC". This happens on PCs that were never activated, and sometimes after a hardware repair, as on Ethan's father's PC. Open Settings, System, Activation, and use Troubleshoot if the PC was previously activated and linked to your Microsoft account, or enter a product key. Until it is activated, the right-click Set as desktop background method in File Explorer still works, so you are not stuck with the default picture.

A policy controls the background. The page says "Some settings are managed by your organization" or the background is "disabled by administrator". On work and school PCs, IT sets the wallpaper deliberately; ask them. On a home PC, a leftover policy from a tweak tool or an old work account is usually to blame. On Pro editions, open gpedit.msc, go to User Configuration, Administrative Templates, Control Panel, Personalization, and set Prevent changing desktop background to Not Configured; also check Desktop, Desktop, Desktop Wallpaper. On Home editions, the same policies live in the registry under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ActiveDesktop and ...\Policies\System, as values named NoChangingWallPaper and Wallpaper; back up the registry, delete those values, and sign out and back in.

The background keeps changing by itself

When the wallpaper changes without you touching it, something is set to change it. Work through these in order.

Theme syncing catches most people out. If you sign in to two PCs with the same Microsoft account and Windows backup is set to remember preferences, changing the wallpaper on one changes the other. To keep them separate, open Settings, Accounts, Windows backup, expand Remember my preferences, and turn off Other Windows settings or personalization syncing where offered. Our guide to themes covers saving a theme so it can be put back in one click.

If none of these apply and the background still changes, check Task Manager's Startup apps page for anything wallpaper-related, and review recently installed programs in Settings, Apps. On a PC used by several people with a single shared account, the simplest explanation is often that someone else changed it; separate accounts, covered below, give everyone their own.

The desktop background is black

A black background that you did not choose has a handful of causes, and the fix depends on which. Activation is the first thing to check, as above, since Windows uses a black background on unactivated PCs after a reset. Accessibility settings are next: in Settings, Accessibility, Visual effects, make sure the option to show the desktop background image, where present, is on, and in Accessibility, Contrast themes, make sure no contrast theme is selected, since those replace the wallpaper with a plain color.

A missing picture file also produces black: if the wallpaper was on a USB drive, a network location or an OneDrive folder that is now online-only, Windows cannot load it. Choose a picture stored in your Pictures folder instead. Corrupted cached wallpaper is a rarer cause; setting a different picture, then setting yours again, usually clears it, and so does deleting the cached copy at %AppData%\Microsoft\Windows\Themes\TranscodedWallpaper and reapplying the picture. Finally, a black background after a Windows update has in the past been a bug affecting some PCs, fixed by a later update, so install any pending updates.

A black background with no icons and no taskbar is a different problem, a desktop that has not loaded; our guide to a black screen after login covers that.

Finally, some graphics driver problems after an update leave the desktop black with icons intact; restarting the graphics driver with Windows + Ctrl + Shift + B, then reapplying the picture, clears those, and our guide to display problems after a Windows update covers the driver side if it recurs.

The background will not change at all

If you choose a picture and nothing happens, start with a restart of File Explorer, which draws the desktop: open Task Manager, find Windows Explorer, and select Restart. Then check the causes above: activation, policies, contrast themes and a picture file Windows cannot read. A picture in an unusual format, such as a WebP saved from a website on an older Windows 10 build or a HEIC photo without the HEIF extension, can fail silently; open the picture in Paint and save it as PNG or JPG, then set it again.

If every method fails, including Set as desktop background in File Explorer, check that the Themes service is running: press Windows + R, run services.msc, find Themes, and make sure it is Running with Automatic startup. Running sfc /scannow in an administrator Command Prompt repairs damaged system files that occasionally break personalization.

Does the wallpaper affect performance or battery?

A static picture or slideshow has no measurable effect on speed. Windows draws the wallpaper once and keeps it cached, and a slideshow only loads a new file when the picture changes. Very large pictures, such as 50-megapixel camera originals, take a moment longer to apply but do not slow the PC afterward, since Windows stores a screen-sized copy.

Two related settings do affect older or low-power PCs slightly. Transparency effects, in Personalization, Colors, add a small graphics load for the frosted look on the taskbar and menus, and turning them off can make a weak PC feel a touch snappier. Animated wallpaper apps use the graphics chip continuously and shorten battery life, which is why their pause-on-battery options exist. On OLED laptops, darker wallpapers use a little less power than bright ones, since dark pixels on OLED draw less current.

Change the background from the command line

For scripts, shortcuts or setting up several PCs, the wallpaper can be changed without Settings. In PowerShell, the registry value WallPaper under HKEY_CURRENT_USER\Control Panel\Desktop holds the picture's path; setting it and then refreshing the desktop applies it:

Set-ItemProperty -Path 'HKCU:\Control Panel\Desktop' -Name WallPaper -Value 'C:\Pictures\family.jpg'
RUNDLL32.EXE user32.dll,UpdatePerUserSystemParameters

The refresh command does not always take effect immediately; signing out and back in guarantees it. The WallpaperStyle value in the same key controls the fit, with 10 for Fill, 6 for Fit, 2 for Stretch, 0 for Center and 22 for Span, and TileWallpaper set to 1 with WallpaperStyle 0 gives Tile. For a shortcut that opens the Background page directly, use the address ms-settings:personalization-background, as our guide to a shortcut to Background settings explains.

For many PCs at once, Group Policy or Intune are the right tools, as the IT section below explains, but the registry method is handy for a single PC where Settings is unavailable, for example in a recovery scenario or a locked-down kiosk you administer yourself. Keep the picture in a folder every user can read, such as C:\Users\Public\Pictures, since a path inside one user's profile fails for other accounts.

Animated and live wallpapers

Windows does not include animated wallpapers, but apps from the Microsoft Store and established game stores add them, drawing a moving scene or video behind your icons. They are safe from official stores and uninstall cleanly, and most pause when a game or full-screen app runs. The costs are battery life and some graphics load, so on laptops use the app's option to pause on battery. Avoid "live wallpaper" downloads from random sites, which are a frequent carrier of unwanted software.

A middle ground is a slideshow with a short interval and shuffle on, which gives a sense of change without any extra software or load.

If you try one, check its reviews for recent updates and its settings for a pause-on-battery option before relying on it, and remember that uninstalling it from Settings, Apps returns the desktop to the picture or slideshow you had before.

Making the desktop easier to see

For older eyes, the wallpaper is part of readability. A calm picture or solid color with little detail behind the icons helps, as does a dark color if the icon labels are white, or a light one if you use a light theme. Larger icons, set by holding Ctrl and scrolling on the desktop, and larger text in Settings, Accessibility, Text size, make a bigger difference than any wallpaper. Keep Auto arrange off and Align to grid on so icons stay where they are put; our guide to auto arrange explains why icons sometimes move on their own.

For Ethan's father, the winning combination was a slideshow of family photos changing hourly, large icons along the left edge, and text size at 125 percent. He has not asked for the swirl back.

Two more small changes help many older users. Turning off Windows spotlight's daily change avoids the confusion of a desktop that looks different every morning, which some people read as something being wrong with the PC. And a slideshow interval of an hour or a day, rather than minutes, keeps the desktop familiar while still bringing new photos; Ethan's father noticed every change at first and asked about each one, until the hourly rhythm became part of the day.

Different backgrounds for each person on a shared PC

Each Windows user account has its own desktop background, so on a family PC everyone can have their own picture without affecting anyone else. That only works if each person signs in to their own account; a shared account shares the wallpaper too, along with everything else. Settings, Accounts, Other users adds accounts, and giving children their own accounts also enables family safety features.

For a child's account, a parent can set a calm background and leave it, but children usually enjoy choosing their own, and nothing they pick can harm the PC; the one thing to watch is wallpaper download sites that push installers rather than plain pictures. Showing them the right-click, Set as desktop background trick on pictures saved to their own Pictures folder keeps it simple and safe.

For IT admins: set or lock the wallpaper

To set a company wallpaper, use Group Policy: User Configuration, Administrative Templates, Desktop, Desktop, Desktop Wallpaper, pointing to a picture on a network share or copied locally by a startup script, with the style set to Fill. Pair it with Prevent changing desktop background under Control Panel, Personalization if users must not change it, or leave that unset so they can. In Intune, the Personalization configuration profile sets desktop and lock screen images on Enterprise and Education editions. Keep the image under a few megabytes and sized for common screens, and expect laptops with different resolutions to crop it with Fill, so keep logos away from the edges.

Avoid locking the wallpaper on PCs where it is not required. Personalization is one of the few parts of a work PC that staff can make their own, and forcing a corporate image on every laptop generates support requests while adding nothing to security. Reserve the lock for shared devices, kiosks and screens visible to the public, where a consistent image matters.

Frequently asked questions

Changing the desktop background is a right-click away, in Settings or straight from a picture in File Explorer, and a slideshow or Windows spotlight keeps it fresh without any effort. When the background misbehaves, the causes are few and predictable: activation, a policy, Spotlight or a slideshow you forgot, theme syncing, a contrast theme or a missing file. Ethan's father now has his grandchildren on screen every hour, and the blue swirl is a memory.
