How to change default lock screen image in Windows 10

In Windows 10, the lock screen image is shown in a number of cases. For instance, if you locked your user session using Win+L or by clicking the user image in the Start Menu, the lock screen image will appear and show the image which is set in your Settings -> Personalization -> Lock screen. But if you sign out or the screen is locked at the user list screen, then Windows 10 shows another image. This is the default lock screen. So, there are two completely separate lock screens in Windows 10. Here is how you can set the default lock screen image in Windows 10.


When you sign out from your Windows 10 user session, after one minute the default Lock screen image appears. If you enable the Ctrl + Alt + Del sign in requirement, it will appear instantly.
Here is how the lock screen image for my user account looks like: Windows 10 per-user lock screen Windows 10 control alt del login screen

And this is the default lock screen image set in my Windows 10: Windows 10 default lock screen

As you can see from the screenshots above, they are two different images.

Unlike the per-user lock screen image, the default one cannot be changed using the Settings app. Here is how to change default lock screen image in Windows 10.

It can be done with a simple Registry tweak. Just do the following.

  1. Open Registry Editor
  2. Go to the following key:
    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization

    Tip: How to jump to the desired registry key with one click.
    If you have no such key, then just create it. Windows 10 create personalization policy reg key

  3. Create a new string value named LockScreenImage. Windows 10 create lockscreenimage value Set its value data to the full path of the desired image which will be used as the lock screen image: Windows 10 set lockscreenimage value

Now the default lock screen background will be set to the specified image: Windows 10 custom default lock screen image

The user lock screen image will remain unchanged:

Windows 10 user lockscreenimage unchanged

The only limitation of this trick is Windows Spotlight. It is not possible to enable it for the default Lock screen.

The same can be done using Winaero Tweaker. Go to Appearance -> Default Lock Screen Background:
Winaero Tweaker default lock screen
Use this option to avoid Registry editing.

You also might be interested in disabling the Lock screen completely. See this article: How to disable the Lock Screen in Windows 10.

    Were is the default lock screen image for Windows 10 located. Somehow I have managed to get mine set to my most recent Spotlight image. I know this is not supposed to be possible but it has happened. I would like the beach cave image back. Thanks.

      Look in C:\Windows\Web\Screen. It and the other default images live there.

    I know this changes the *default* lock screen image, but is there a way to change the *user* lock screen image through the registry? Yes, specifically through the registry, and not through the personalization menu.

    This feature does not work on Windows 10 anniversary edition. In fact it also messes up the ability to change lock screen settings. Once you set this the option to change the lock screen just has a message at the top saying this is controlled by your company. It also changes the ability to change the diagnostic and usage settings from full to basic or enhanced. it again just says this option is controlled by your company.
    I am running Windows 10 anniversary HOME edition.

    Doesn’t work in Anniversary Update (1607). Well, it does work but it makes it where the user cannot change their lock screen. That’s a problem. I just want to change the DEFAULT lock screen.

    Why is it doing this?

      It forces the image for ALL lockscreens.
      The most suitable option to use the same image for all lockscreen at once.
      Not so convenient, but this is all that Microsoft allows us.

        What do you mean by “use the same image for all lockscreen at once?” Just not sure what that means.

          In short, I meant the following.
          1. Revert the tweak.
          2. Change the user lock screen image.
          3. Apply the tweak again.

            Same result. It locks so that the user can’t change it.

          2. Sergey Tkachenko Post author

            After you reverted the tweak, try to do the following.
            Open the command prompt and type
            gpupdate /force
            The result should be as follows:

            C:\Users\Winaero>gpupdate /force
            Updating policy…

            Computer Policy update has completed successfully.
            User Policy update has completed successfully.

            C:\Users\Winaero>

            Then restart your PC.
            This should restore the ability to change the user lock screen.

    Definitely this tweak now does not work as before in the Anniversary Update, if you have auto logon enabled.
    If you have to put in your password on logon, it does seem to still work.
    With auto logon enabled you can have the cave picture or a plain colour, no alternative image seems to be possible.

    This did not work for me, and i have tried everything. There is no way to change the Lock screen that is displayed when you first boot your PC. if Anything, the best i was able to do was to turn off the lock screen. everyone has a salutation for this, none of them work.

    This did not work. I tried manually updating the registry and using the software. Same result. Still shows the beach cave image. Anyone have any ideas?

    This doesn’t seem to work with the April 2018 version of Windows 10. I tried it numerous times with JPEG and PNG images without luck. Possibly the structure of the settings has been changed by Microsoft.

    I had trouble with Lock and Logon background images refusing to change regardless of what I tried until I deleted (renamed) the two files: roaming.lock and settings.dat found at:
    \AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager_\Settings

    I hope this helps others having similar difficulties. Perhaps this seemingly safe and easy action could be added under-the-hood of the WinAero action of changing the lock screen.

    Definitely doesn’t work in Win10 1903.

    I’ve found a solution that works on the latest Windows 10 Pro Build 1903.
    1. Go to C:\Windows\Web\Screen and take the ownership of img100.jpg
    2. Rename it.
    3. Copy an image you like to this folder as img100.jpg
    4. Use the Winaero Tweaker or the above “How to change default lock screen image in Windows 10” with the same picture that you will put in other folder.
    5. To be on the sure side Open CMD prompt as Administrator and write: gpupdate /force
    6. Restart your PC.

    The picture in default lock screen image will change.
    (It will take few days until the Lock screen picture will change. In my case it took 3 days).

      This worked for me with the latest Windows 10 Pro Build 1903:

      1. Create the following folder if it does not exist: C:\Windows\System32\oobe\info\backgrounds

      2. Copy a JPG image you like to this folder and name it backgroundDefault.jpg

      3. In the Registry Editor, browse to HKLM\SOFTWARE\Policies\Microsoft\Windows\Personalization and ensure that the following properties exist with the specified values:
      [REG_SZ] “LockScreenImage”: “C:\Windows\System32\oobe\info\backgrounds\backgroundDefault.jpg”
      [REG_DWORD] “NoLockScreen”: “0x00000001 (1)”

      Alternatively, here are the contents of a .REG file:

      [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization]
      “LockScreenImage”=”C:\\Windows\\System32\\oobe\\info\\backgrounds\\backgroundDefault.jpg”
      “NoLockScreen”=dword:00000001

      4) The change should take effect immediately. If not, open a CMD prompt as Administrator and execute the following command: gpupdate /force

    A few of these techniques work for me, Win10 v1803, 1809, 1903

    WORKS – ToneDeF method using OOBE
    WORKS – WinAero (original posting) registry ‘Personalization’

    However – All of these (and other) methods only seem to work if the image is the same resolution as the current monitor setting. More specifically, the image displays at 1:1 resolution, so if you have a company logo or image that starts on the left, or right, it may be cropped. The lockscreen does not scale.

    Worse is when there are multple users that each use a different monitor resolution. These methods do not work proper.

    My solution, which is clumsy and high maintenance – until I find a better method is to replace the actual displayed lockscreens with the actual screen sizes that Windows detects and displays. These are located in a system locked folder at: C:\ProgramData\Microsoft\Windows\SystemData\ and within this folder are folders for each user, and each screen resolution you have. The system folder is .\S-1-5-18\ReadOnly\

    To manage this, you need to take ownership such as:
    takeown /F C:\ProgramData\Microsoft\Windows\SystemData /R /D N

    Then allow access:
    icacls C:\ProgramData\Microsoft\Windows\SystemData /grant {me}:(F) /T

    Baffling why Microsoft chooses to make such a superficial cosmetic task a key system component and rewrite the settings every major update.

    We use a script to cleanup all the Microsoft junk, unwanted and forces changes and other things constantly.
