Why Change Your Wallpaper Automatically
A single wallpaper gets boring fast. The same photo greets you every morning, and after a few weeks you stop noticing it altogether. Changing your wallpaper automatically keeps your desktop feeling fresh without you having to remember to do anything. Windows 11 can rotate through a folder of your favourite photos, show you a new picture from around the world every day, or follow a schedule you set yourself, and once it is configured, it just works in the background.
There are several ways to do it, and they suit different people. The built-in slideshow is the simplest: point Windows at a folder of images and it cycles through them on a timer. Bing Wallpaper gives you a new professional photograph every day, which is ideal if you like variety but do not want to manage a collection. Windows Spotlight does something similar with images from Microsoft. And if you want full control, you can schedule wallpaper changes with Task Scheduler, or use a free third-party app that adds features Windows does not have, like changing the wallpaper based on the time of day. This guide covers all of them, starting with the easiest.
Method 1: Use the Built-In Slideshow (Easiest)
The slideshow feature has been in Windows for years, and it is still the most reliable way to rotate wallpapers automatically. You choose a folder full of images, pick how often they change, and Windows does the rest. It works on the lock screen and the desktop, and it needs no extra software.
Step 1: Put your images in one folder. Create a folder, for example Pictures, then Wallpapers, and copy the images you want to use into it. Windows will use every image in the folder, so remove any you do not want to see. JPG and PNG files both work. For the best results, use images that are at least as large as your screen resolution, so they do not look blurry when stretched across the desktop.
Step 2: Open the background settings. Right-click on an empty part of the desktop and choose Personalize, then Background. You can also open Settings, then Personalization, then Background. At the top of the page you will see a dropdown labelled Personalize your background.
Step 3: Choose Slideshow. Click the dropdown and select Slideshow. Two new options appear: Choose a photo album, and Change picture every. Click Browse under Choose a photo album and select the folder you prepared in Step 1.
Step 4: Set how often the picture changes. Click the Change picture every dropdown and pick an interval. The options range from 1 minute to 1 day. For most people, 1 hour or 6 hours is a good balance: the desktop changes often enough to stay interesting, but not so often that it becomes distracting. If you want a new picture every time you sit down at the computer, choose 1 day and the wallpaper will change each morning.
Step 5: Choose the fit and shuffle. Turn on Shuffle if you want the pictures in a random order instead of alphabetical. Then choose a fit for your pictures, usually Fill, which crops the image slightly to cover the whole screen without stretching it. Fit leaves black bars if the image is the wrong shape, so Fill is the safer choice for most photos.
That is all there is to it. Windows will now change your wallpaper on the schedule you set. If you ever want to skip to the next picture immediately, right-click on the desktop and choose Next desktop background, which appears while a slideshow is active.
Method 2: Get a New Wallpaper Every Day with Bing Wallpaper
If you like the idea of a fresh picture every day but do not want to build your own collection, the free Bing Wallpaper app from Microsoft is the answer. Each day it downloads the Bing homepage image, which is usually a striking landscape, wildlife, or travel photograph, and sets it as your desktop and lock screen wallpaper. The images are professionally shot and change daily, so your desktop never looks the same two days in a row.
Step 1: Download Bing Wallpaper. Go to the Microsoft Store, search for Bing Wallpaper, and install it. It is free and published by Microsoft, so there is no advertising or bundled software to worry about. You can also download it from Microsoft’s Bing Wallpaper page if you prefer.
Step 2: Let it set your wallpaper. When you first open the app, it asks whether it can change your wallpaper and lock screen daily. Accept, and it will immediately set today’s Bing image as your wallpaper. The app runs quietly in the system tray from then on.
Step 3: Explore past images. Click the Bing Wallpaper icon in the system tray, near the clock, and you will see today’s image plus a small gallery of recent days. If you liked yesterday’s photo better than today’s, you can switch back to it from the gallery. The app also tells you where each photo was taken, which is a nice touch if you enjoy travel photography.
The only thing to watch is that Bing Wallpaper sets both the desktop and the lock screen by default. If you prefer a different lock screen image, open the app’s settings and turn off the lock screen option, then set your lock screen separately in Settings, then Personalization, then Lock screen.
Method 3: Use Windows Spotlight for Daily Images
Windows Spotlight is built into Windows 11 and shows a rotating selection of images from Microsoft on your lock screen. On newer versions of Windows 11, you can also use it for the desktop background, which makes it a zero-install alternative to Bing Wallpaper.
Step 1: Open the background settings. Right-click the desktop, choose Personalize, then Background, just as in Method 1.
Step 2: Choose Windows Spotlight. Click the Personalize your background dropdown and select Windows Spotlight, if it appears. On some versions of Windows 11, this option is only available for the lock screen, not the desktop background. If you do not see it, use Method 2 instead, which gives you the same daily-image experience.
Step 3: Enjoy the daily rotation. Once selected, Windows downloads a new Spotlight image regularly and sets it as your background. Right-clicking the desktop gives you a small Spotlight icon you can use to learn more about the picture or to switch to the next one if you do not like the current image.
Spotlight images are a mix of landscapes, architecture, and nature photography, similar in spirit to Bing Wallpaper. The main difference is that Spotlight is built in, so there is nothing to install, while Bing Wallpaper gives you a small gallery of recent images to browse through.
Method 4: Schedule Wallpaper Changes with Task Scheduler (Advanced)
If you want your wallpaper to change at specific times, for example a bright photo in the morning and a dark one at night, Task Scheduler can do it. This method is more work than the slideshow, but it gives you exact control over when each picture appears, and it uses only tools already built into Windows.
Step 1: Prepare your images and note their paths. Decide which pictures you want at which times, and note the full file path of each one, for example C:\Users\YourName\Pictures\Wallpapers\morning.jpg. The paths must not contain any mistakes, or the task will fail silently.
Step 2: Open Task Scheduler. Press the Windows key, type Task Scheduler, and open it. Click Create Basic Task in the panel on the right, and give the task a name like Morning Wallpaper.
Step 3: Set the trigger. Choose Daily as the trigger, then set the time you want the wallpaper to change, for example 7:00 AM. Click Next.
Step 4: Set the action. Choose Start a program as the action. In the Program/script box, type powershell.exe. In the Add arguments box, type a command that sets the wallpaper, for example: -Command “Set-ItemProperty -Path ‘HKCU:\Control Panel\Desktop’ -Name Wallpaper -Value ‘C:\Users\YourName\Pictures\Wallpapers\morning.jpg’; rundll32.exe user32.dll, UpdatePerUserSystemParameters”. Click Next, review the summary, and click Finish.
Step 5: Repeat for each time of day. Create a separate task for each wallpaper change you want, for example one at 7:00 AM for the morning picture and one at 7:00 PM for the evening picture. Test each task by right-clicking it in Task Scheduler and choosing Run, then checking that the wallpaper actually changes.
This method is powerful but fragile: if you move or rename an image, the task that points to it stops working, and Windows gives you no warning. If you only want a regular rotation, Method 1 is simpler and safer. Use Task Scheduler only when you genuinely need time-based changes.
Method 5: Use a Free App for Extra Features
If the built-in options are not enough, a few free apps add features Windows does not have. Lively Wallpaper, available free from the Microsoft Store, lets you use animated wallpapers, videos, and even web pages as your background, and it can change the wallpaper based on the time of day or the weather. Wallpaper Engine, a paid app on Steam, offers a huge library of community-made animated wallpapers with similar scheduling features. Both are popular and well reviewed, but they use more system resources than a static slideshow, so they are best on a reasonably powerful computer.
Before installing any wallpaper app, check what it runs in the background and whether it shows advertising. Lively Wallpaper is open source and shows no ads, which is why it is the safest recommendation. Avoid random wallpaper apps from unknown developers, especially ones that ask for administrator access, because a wallpaper app has no legitimate reason to need it.
How to Change the Lock Screen Wallpaper Too
The lock screen has its own background settings, separate from the desktop. To change it, open Settings, then Personalization, then Lock screen. You can choose Picture, Slideshow, or Windows Spotlight, just like the desktop. If you use Bing Wallpaper, it can manage the lock screen for you, as described in Method 2. A matching desktop and lock screen looks tidier, but there is no rule that they have to match, so set each one however you like.
One thing worth knowing is that the lock screen slideshow uses the same folder system as the desktop slideshow. If you point both at the same folder, they will show the same pictures, which is a simple way to keep the two in sync.
Tips for a Good Automatic Wallpaper Setup
Use high-resolution images. A wallpaper that is smaller than your screen will look blurry when stretched. Aim for images that are at least 1920 by 1080 pixels for a standard monitor, and larger if you have a 4K display. Most photos taken on a modern phone are easily large enough.
Curate the folder. A slideshow is only as good as the pictures in it. Every few months, open the folder and remove images you are tired of, and add a few new ones. A folder of 20 to 50 pictures is a good size: small enough to manage, large enough that you do not see the same picture twice in one day.
Mind the battery. On a laptop, changing the wallpaper every minute uses a tiny amount of extra power, because Windows has to load and draw a new image each time. It is not enough to worry about, but if you are trying to squeeze every minute out of your battery, choose a longer interval, like 6 hours or 1 day.
Keep personal photos out of shared folders. If other people use your computer, remember that a slideshow will show every image in the folder, including any you would rather keep private. Keep your wallpaper folder separate from your general photo library, and only put images in it that you are happy for anyone to see.
Common Problems and How to Fix Them
The wallpaper does not change. First, check that the slideshow folder still exists and still contains images. If you moved or renamed the folder, Windows silently stops changing the picture. Open Settings, then Personalization, then Background, and re-select the folder. Also check that the Change picture every interval is not set to 1 day when you expected hourly changes.
Only some pictures appear. Windows skips images it cannot read, including corrupted files and some unusual formats. If a picture never appears, open it in the Photos app: if it does not open there either, the file is damaged. Convert it to JPG or PNG and try again. Very large images, over about 20 MB, can also be skipped on slower computers.
The wallpaper looks stretched or squashed. This is a fit problem. Open the background settings and change Choose a fit for your desktop image to Fill, which crops the edges instead of stretching the picture. If the picture is the wrong shape for your screen, for example a portrait photo on a wide monitor, no fit setting will make it look right, so use landscape images for the desktop.
Bing Wallpaper stopped updating. Check that the app is still running in the system tray. If it closed, reopen it from the Start menu. If it is running but the picture has not changed in days, check your internet connection, then right-click the tray icon and choose Refresh. Reinstalling the app from the Microsoft Store fixes most persistent problems.
The slideshow changes the picture but the lock screen does not. The desktop and lock screen are independent, as explained above. Set the lock screen separately in Settings, then Personalization, then Lock screen, and choose Slideshow there with the same folder if you want them to match.
Frequently Asked Questions
Does changing the wallpaper automatically slow down my computer? No, not noticeably. Loading a new picture every hour uses almost no resources. Animated wallpaper apps use more, because they run constantly, but a static slideshow has no measurable effect on performance.
Can I use my own photos as wallpapers? Yes, and they make the best slideshows. Copy your favourite photos into a folder and point the slideshow at it. Just make sure the photos are high resolution, and remember that anyone who sees your screen will see those photos.
Can I set different wallpapers on each monitor? Yes. In Settings, then Personalization, then Background, right-click on a picture in the recent images section and choose Set for monitor 1 or Set for monitor 2. The slideshow setting applies to all monitors at once, so if you want different automatic rotations per monitor, you will need a third-party app.
Will the slideshow keep working after a Windows update? Usually, yes. Occasionally a major Windows update resets personalization settings, including the slideshow folder. If your wallpaper stops changing after an update, just re-select the folder in the background settings.
Is Bing Wallpaper safe? Yes. It is published by Microsoft, it is free, and it contains no advertising. It does send a small amount of diagnostic data to Microsoft by default, which you can turn off in the app’s settings if you prefer.
Final Thoughts
For most people, the built-in slideshow is all you need: a folder of pictures you like, a change every hour or so, and nothing else to think about. If you want a new picture every day without managing a collection, Bing Wallpaper or Windows Spotlight does the job for free. And if you want exact control over when each picture appears, Task Scheduler is there when you need it. Pick the method that matches how much effort you want to spend, set it up once, and let your desktop surprise you a little every day.
