Lock Screen Default Background Image - Change in Windows 8

  1. #10


    If you don't want to see that hideous "rainbow" lock screen and pre-sign-in screen your best bet is to disable the lock screen altogether (see Lock Screen - Enable or Disable in Windows 8) then, if you have Windows 8. update it to 8.1 via the Windows Store, and finally install the latest Windows update (see Windows 8.1 August update now available - CNET). Hope this helps.

    Restarted, and the default lock screen is still what I set in PC Settings. To verify, I changed the image again through PC Settings and restarted again. The lock screen background was the new image. Have you tried it on a computer with only one user account? Or is there another factor that might be causing this? Either way, I'm not complaining. This is exactly what I wanted.

    Klsrd,

    I'm thinking that since you are the only account on the computer, you may be see your lock screen as the last user instead of the default lock screen.

    If you like, as a test to play, create a new user account and sign in and out of it to test and see if you see the default lock screen now, or still the same. You can delete the account afterwards.

    I was going to refuse out of laziness, but curiosity got the better of me and it only took a minute. After enabling the guest account and signing out, the lock screen was the image that I previously set as the default lock screen via your second method. Disabling the guest account brought back the lock screen I selected through PC Settings. So the theory is probably correct. When there is only one account, the default lock screen seems to be bypassed and the user lock screen is used in its place. For those with only one user account, there's no need to go through the trouble of changing the default lock screen. Good news for me! Thank you for the tutorial nonetheless, it's interesting to see how things are organized within an OS.

    Great news. Thank you for taking the time to test the theory on your system.

    Hello, I know this thread is old, but I hope this is the appropriate place to ask questions.

    This guide worked beautifully and I was able to change my default lockscreens. I was wondering though, would you happen to know which locations the thumbnails are stored at? It's just a small detail, but it feels weird clicking on the thumbnail and the pictures don't match. They also have the names: Seattle, 1, 2, 3, 4, 5, when I hover over them, so I tried doing a file search, but couldn't find them. Is there any way I can find out where they pull the thumbnails from? I'm amazed you were even able to find the locations of the lock screen images, so I thought that was really cool. Anyways, thank you so much for this great tutorial!

    The best I could find was a cache of the image previews stored at C:\Users\USERNAME\AppData\Roaming\Microsoft\Windows.

    Hello thunderstorm, and welcome to Eight Forums.

    This tutorial isn't for the lock screen displayed when you are still signed in to your user account, but for the lock screen shown when no users are signed in.

    The lock screen images that come with Windows are stored in the folder in step 3 of Option Two. You could check to make sure that they are still there and correctly named. An easy way to fix the recent thumbnails is to keep changing the lock screen until the thumbnails have been replaced with ones that show the correct image, then change your lock screen back to what you wanted.

    Hope this helps,
    Shawn

    I kept changing the lock screen by clicking on the thumbnails, but nothing happens. The default lock screen that shows when i log off is the custom one I picked (I mean the default one which I had replaced following the tutorial). However, it still shows up as the default seattle thumbnail is what I mean. After I reset my thumbnails to default, it shows back up. For example i click on the honeycomb and a black rose shows up, I click on the seattle picture, my default star background shows up, I click on the piano keys but it's a deck of cards. So the thumbnails don't match the pictures I've replaced.

    Not sure if this explains it, but the pictures I'm selecting in the "Change PC Settings" is the ones I've all replaced.

    Did you also change your lock screen using the method below?

    Instead of just clicking on the thumbnails to change the lock screen, browse to and select a different image each time instead until they replace your thumbnails to see if the thumbnails will then show the correct ones when clicked on afterwards.

    Ah, not quite what I'm looking for, but thank you anyways.

    I can customize my user lock screen just fine that way. I was just trying to look for a way to completely replace the default files, including the thumbnail, because from your tutorial, it looks like it replaces the default lockscreen flawlessly, but missing a slight detail. I replaced the default Seattle lock screen, but not the Seattle thumbnail that goes along with it, but I can change my user lock screens with no problem and they have the correct thumbnails. It was mostly just to experiment and learn how you find the files you need to edit. I wanted to learn about how windows generates the thumbnails and where it stores them. It's just a silly edit I want to make - not really anything as important.

    Haha, sorry if this is confusing, but I appreciate the time you take to try and answer! By the way, I forgot to thank you for the welcome. Thanks!

    Edit: I found a person with the same question as mine online, but worded much better.
    ...do you know how to properly "replace" the 6 lock screen images that are located in the C:\Windows\Web\Screen folder? I've replaced these and their matching files under the C:\Windows\WinSxS folder structure, but the thumbnails in the Personalization Settings area for the lock screen still show the original (Microsoft included) images and don't reflect the images I have replaced them with.
    It looks like the answer is in the Windows\system32\Windows.UI.Immersive.dll !!!
