How to pushdown a png file as domain-joined desktop/laptop lock screen?

This using MS Windows 2016 server based AD Domain. we have 1 png file need to push down to all of the MS Windows 10 desktops and laptops as a "Lock Screen". That means when the desktop/laptop is locked or user click Windows Key + L, this png file will appear. We also users no able to change it.

Can we use GPO to pushdown? if so, how to make it work?

Try below steps:

  1. First, you’ll need to create a shared folder on your Windows Server 2016-based AD Domain and place the PNG file in that folder. Make sure that all domain users have read access to this shared folder.
  2. Next, open the Group Policy Management Console (GPMC) on your server and create a new Group Policy Object (GPO) or edit an existing one.
  3. In the Group Policy Management Editor, navigate to Computer Configuration > Policies > Administrative Templates > Control Panel > Personalization.
  4. Double-click on Force a specific default lock screen and logon image and set it to Enabled.
  5. In the Path to lock screen image field, enter the UNC path to the PNG file in the shared folder you created earlier (e.g., \\SERVER\SharedFolder\LockScreen.png).
  6. Click OK to save your changes.
  7. Link the GPO to an OU that contains all of the computers you want to apply this setting to.
  8. Finally, run gpupdate /force on each computer or wait for Group Policy to refresh automatically.
  9. After completing these steps, all domain-joined desktops and laptops running Windows 10 should display the specified PNG file as their lock screen when locked or when a user presses Windows Key + L.
