    How to Change the Default Lock Screen Background Image in Windows 8 and 8.1


    information   Information
    In Windows 8 and 8.1 there are two "Lock" screens.

    • The user lock screen is the one that displays when a user locks the PC while still signed in to Windows, and when the user is selected on the sign in screen, times out, and returns to the lock screen. Each user is able to change their lock screen background image to an image of their choice.
    • The default Lock screen image is the one that displays when there are no users currently signed in to Windows or selected on the sign in screen.


    While it's easy to change your lock screen image, Windows doesn't have an easy way to change the default lock screen image.

    This tutorial will show you how to change the default lock screen (aka: pre sign-in screen) background image to an image of your choice in Windows 8, Windows RT, Windows 8.1, and Windows 8.1 RT.

    You must be signed in as an administrator to be able to do the steps in this tutorial.

    Hello usmangta,

    I'm assuming you mean in Option Two, but why not, and what are you seeing different than in the tutorial?

    sean is the WinAero suggestions still valid? looking on their site, there's confusion there. they speak of a different 32/64 version "new" for 8.1. Then there is one and only one download link for 8/8.1, then there is a string of comments as to bugs under varying scenarios, especially 8.1. Just checking before I try to repair 8.1 for MS

    Hello Cognus,

    There's one download, but there's a 32-bit and 64-bit version of the program in the ZIP file. Be sure to use the correct version that's the same as what Windows you have installed.

    I'm not sure about the reported issues with it since it works fine for me, but if you are uncertain, you could always do the manual Option Two methods.

    The complicated hack above should never have been necessary. Hopefully it will dawn on Microsoft one day that its hideous Windows 8.1 lock screen and pre-sign-in screen are driving away its customers and it will replace them in the next Windows 8.1 Update.

    There might be a file size limitation for the lock screen image. I tried using a 1.30MB jpg and the lock screen did not show the image. It was just a plain blue background. The other images I tried worked fine, and they were all smaller files. Same 1920x1200 res.

    Edit: After using Option Two to change the lock screen, I found that I could do the same thing in PC Settings. Not sure if this is from a recent update but it's much more convenient.

    Hello klsrd, and welcome to Eight Forums.

    I'm not sure of the exact file size limit, but yeah reducing the file size should help.

    This tutorial is to change the default lock screen used when no users are signed in.

    The one in PC settings is for your lock screen like below instead.

    I see. I guess this tutorial wasn't for me since I only have one user account? The lock screen when I'm signed out is still the one I selected in PC Settings.

    Restart the PC to see what the default lock screen is for you before any user is signed. It should be the example screenshot in this tutorial by default unless already changed.
