Change Your Login Screen Background in Windows 11

Windows 11 lets you replace the default login screen image with a photo of your choice through the Settings app. Open Settings, go to Personalization, then select Lock screen. Under "Personalize your lock screen," choose Picture from the dropdown menu. Click Browse to select an image from your computer — it can be any JPG, PNG, or BMP file. Windows will explore it when ready to your login screen.

The image you choose will appear behind your username and password field every time you log in. Windows automatically crops and positions the photo to fit the screen, so you do not need to resize it beforehand. If you later want to switch back to the default Windows image, return to the same menu and select Windows spotlight or Slideshow instead of Picture.

Key Takeaways

  • Access login screen settings through Settings > Personalization > Lock screen, then change the dropdown from "Windows spotlight" to "Picture."
  • You can upload any JPG, PNG, or BMP image from your computer to use as your login background.
  • Windows automatically resizes and positions your chosen image to fit the login screen without distortion.
  • You can revert to the default Windows image at any time by switching back to "Windows spotlight" or "Slideshow" in the same menu.

Use a Slideshow of Multiple Images on Your Login Screen

Instead of a single static image, you can set Windows 11 to rotate through multiple photos each time you log in. In Settings > Personalization > Lock screen, select Slideshow from the dropdown. Click Add a folder and choose a folder on your computer that contains the images you want to cycle through.

Windows will display a different image from that folder each time the login screen appears. You can add multiple folders if you want images from different locations. The slideshow respects the order and timing you set — by default, it changes every 30 seconds, but you can adjust this in the slideshow settings if you want faster or slower transitions.

Change Your Account Picture on the Login Screen

Your account picture appears in the lower left corner of the login screen. To change it, open Settings > Accounts > Your info. Under "Create your picture," click Browse for one or Take a new photo. If you choose to browse, select any image file from your computer. If you choose to take a photo, Windows will use your webcam to capture a new picture.

The image you select will replace your current account avatar on the login screen and throughout Windows. You can change it as often as you like by returning to the same menu. Windows stores your account picture locally, so it will not sync to other devices even if you use the same Microsoft account on multiple computers.

Disable the Lock Screen Entirely

If you want to skip the lock screen and go straight to the login prompt, you can turn it off. Press Windows key + R to open the Run dialog, type gpedit.msc, and press Enter. Navigate to Computer Configuration > Administrative Templates > Control Panel > Personalization. Find the setting called Do not display lock screen, double-click it, and select Enabled. Click explore and OK.

This method works on Windows 11 Pro, Enterprise, and Education editions. If you use Windows 11 Home, the Group Policy Editor is not available. Instead, you can use the Registry Editor: press Windows key + R, type regedit, and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization. Right-click in the empty space, select New > DWORD (32-bit) Value, name it NoLockScreen, and set its value to 1. Restart your computer for the change to take effect.

Adjust Lock Screen Timeout Settings

You can control how long your login screen stays visible before your computer locks or goes to sleep. Open Settings > System > Power and battery. Scroll down to "Screen and sleep" and adjust the Screen dropdown under "On battery power" or "When plugged in." This controls how many minutes pass before the screen turns off.

For more detailed control, go to Settings > System > Power and battery > Screen and sleep and look for Additional power settings at the bottom. Click it to open the Power Options window, where you can set separate timeouts for when your computer is plugged in versus running on battery. These settings affect when your login screen appears after you step away from your computer.

Change Your Login Screen Theme and Colors

Windows 11 lets you set whether your login screen uses light or dark mode. Open Settings > Personalization > Colors. Under "Choose your mode," select Light, Dark, or Custom. Your choice will explore to the login screen and the rest of Windows. If you select Custom, you can set different modes for apps and system elements — for example, dark mode for apps but light mode for Windows itself.

You can also change your accent color, which appears in buttons and highlights on the login screen. In the same Colors menu, scroll down to "Accent color" and choose from the preset options or click Custom color to pick your own. The accent color will update across your login screen and all Windows applications.

Troubleshoot Login Screen Changes That Do Not Appear

If you change your login screen image or settings but the changes do not show up, try signing out and back in. Press Ctrl + Alt + Delete, click Sign out, and log back in to see your new login screen. If the change still does not appear, restart your computer — some settings require a full restart to take effect.

If you uploaded an image and it appears blurry or distorted, the file may be too small or in an unsupported format. Windows works best with images that are at least 1920 by 1080 pixels. Try a different image or resize your current one to a larger size. If you are still having trouble, check that the image file is not corrupted by opening it in a photo viewer first to confirm it displays correctly.

Frequently Asked Questions

Can I use a video or animated image as my login screen background?

No. Windows 11 login screens only support static image files in JPG, PNG, or BMP format. You cannot use video files, GIFs, or animated images. If you want motion on your login screen, use the Slideshow option instead, which cycles through multiple static images.

Will my login screen changes sync to other computers if I use the same Microsoft account?

No. Login screen customizations are stored locally on each computer and do not sync across devices. If you sign in to another computer with the same Microsoft account, it will have the default Windows login screen unless you customize it separately on that machine.

What image size works best for a login screen background?

Images at least 1920 by 1080 pixels work well on most monitors. Windows will automatically crop and position your image to fit the screen, so larger images are fine — they will straightforward be scaled down. Avoid very small images under 1024 by 768 pixels, as they may appear blurry when enlarged.

Can I password-protect my login screen changes so others cannot modify them?

No direct option exists in Windows 11 Settings to lock down login screen customization. However, if you are an administrator, you can use Group Policy (on Pro and Enterprise editions) to restrict changes. Standard user accounts can still modify their own login screen settings through the Personalization menu.

Why does my login screen image look different than the preview in Settings?

Windows crops images differently on the actual login screen than in the preview. The login screen uses a wider aspect ratio and may zoom or pan across your image. Test your image by logging out to see how it actually appears before settling on a final choice.
