Change Windows 8 Lock Screen: Full Guide

You can change the Windows 8 lock screen by opening PC Settings, selecting Personalize, and then Lock Screen, where you can pick a new background image or app. This guide walks you through every method, including using your own photos, enabling the slideshow, and choosing which apps show quick status on the lock screen.

What the Lock Screen Is in Windows 8

The lock screen in Windows 8 is the full-screen display that appears when you boot the PC, wake it from sleep, or press Windows+L. It shows the time, date, and a set of app notifications (like new email or calendar alerts) before you sign in. Unlike the Start screen or desktop, the lock screen is meant to be glanceable—you see it for a few seconds, then swipe or click to enter your password or PIN.

Windows 8 introduced this lock screen as a replacement for the simple login screen of Windows 7. It supports a background image, a slideshow, and up to seven “quick status� apps that display small icons and counts (e.g., Mail shows the number of unread messages). You can change the appearance and behavior entirely through the PC Settings app, not the Control Panel.

How to Change the Lock Screen Background

The most common change is swapping the default image for one of your own. Here’s how:

  1. Open the Charms bar (swipe from the right edge of the screen, or press Windows+C).
  2. Select Settings and then Change PC settings at the bottom.
  3. In PC Settings, choose Personalize from the left sidebar.
  4. Click Lock Screen at the top of the Personalize page.
  5. You’ll see a row of built-in images. Click one to apply it immediately. To use your own photo, click the Browse button (the folder icon) and select any image file (JPG, PNG, BMP) from your computer.

If you want to use a picture from your Pictures library, you can also right-click the image in File Explorer and choose Set as lock screen from the context menu. That shortcut works in Windows 8 and 8.1.

Using a Slideshow as Your Lock Screen

Windows 8.1 (but not the original Windows 8) added a slideshow option. If you have Windows 8.1 or later, you can cycle through multiple images automatically:

  1. Go to PC Settings > Personalize > Lock Screen.
  2. Click the Slideshow toggle to turn it on.
  3. Choose Add a folder and select a folder that contains your pictures. You can add multiple folders.
  4. Optionally, set the slideshow to use pictures from both your Pictures library and OneDrive (if you have OneDrive set up).
  5. Adjust the “When my PC is inactive, show the lock screen instead of turning off the screen� option if you want the slideshow to appear when idle.

The slideshow uses the Pictures library by default. If you add a folder that isn’t in that library, Windows will ask for permission to access it. The slideshow only runs when the PC is on battery or plugged in—you can control that in the same settings page.

Choosing Which Apps Appear on the Lock Screen

You can show quick status from apps like Mail, Calendar, Messaging, or Weather. To choose them:

  1. In PC Settings > Personalize > Lock Screen, scroll down to Lock screen apps.
  2. Click the “+� icon under “Choose an app to display quick status� and pick an app from the list. That app will then appear as a small icon at the bottom left of the lock screen.
  3. You can add up to seven apps. The first app you choose will show detailed status (e.g., the next calendar appointment). The others show only a count or a small icon.
  4. To remove an app, click its icon and select Don’t show quick status here.

Note that only apps designed for Windows 8 (Metro/Store apps) can appear on the lock screen. Traditional desktop programs cannot be added.

Common Problems and Fixes

Sometimes the lock screen won’t change or the slideshow doesn’t work. Here are typical issues:

  • Image doesn’t change after selecting it: Make sure you clicked the image and then clicked Save (if you’re using a custom image). In some builds, you need to press the Back button to return to the main Personalize page.
  • Slideshow is grayed out: The slideshow option is only available in Windows 8.1 and later. If you have Windows 8 RTM, you can’t use it. Check your version by pressing Windows+R, typing winver, and pressing Enter.
  • Slideshow doesn’t show all images: The slideshow only uses images from the folders you added. Make sure the images are in a supported format (JPG, PNG, BMP, GIF) and that the folder is accessible. If you added a network folder, it may not work when the PC is locked.
  • Lock screen app icons don’t appear: The app must be installed and signed in (for apps like Mail or Calendar). If an app is removed, its icon disappears automatically.

If the lock screen still won’t change, restart the PC. A full restart often clears temporary glitches.

How to Disable the Lock Screen Completely

Some users prefer to skip the lock screen and go straight to the password prompt. To disable it:

  1. Press Windows+R, type gpedit.msc (only in Pro or Enterprise editions) and press Enter.
  2. Go to Computer Configuration > Administrative Templates > Control Panel > Personalization.
  3. Double-click Do not display the lock screen.
  4. Set it to Enabled and click OK.

If you have Windows 8 Home (which lacks gpedit.msc), you can use a registry tweak: navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization, create a DWORD value named NoLockScreen, and set it to 1. Then restart. This is a system policy change, so do it carefully.

Lock Screen vs. Sign-in Screen

Many people confuse the lock screen with the sign-in screen. The lock screen is the pretty image with the clock; the sign-in screen is the one where you type your password. In Windows 8, you can change the lock screen background independently from the sign-in screen background. However, if you set a custom lock screen image, the sign-in screen will use a blurred version of that same image by default. You cannot change the sign-in screen background separately in Windows 8—it always mirrors the lock screen (blurred). In Windows 8.1, you can disable the blur effect via PC Settings > Personalize > Lock Screen > “Show my desktop background picture on the sign-in screen.�

Frequently Asked Questions

Can I use a GIF as my lock screen background? No, the lock screen only supports static images (JPG, PNG, BMP). Animated GIFs will show only the first frame.

Why does my lock screen revert to the default image? This can happen if you have a Group Policy that enforces a specific lock screen image. Check the same policy location mentioned above for “Force a specific default lock screen image.� If that policy is enabled, your changes will be overridden.

How do I change the lock screen timeout? The lock screen appears after the screen turns off, which is controlled by the power plan’s “Turn off the display� setting. You can adjust that in Control Panel > Power Options > Edit plan settings. There is no separate lock screen timeout.

Can I use a different lock screen for each user? Yes, each user account can have its own lock screen background. Changes you make in PC Settings apply only to your account.

Does the slideshow drain battery? Yes, because it keeps the screen on and loads images. You can limit it by choosing “On battery, play a shorter slideshow� or by turning off the slideshow when on battery power.

What if I don’t have a “Lock screen� option in PC Settings? That option is present in Windows 8 and 8.1. If you don’t see it, you might be using an older build or a device with a non-standard display driver. Update your graphics driver and re-check.
