Disable Lock Screen Slideshow via Regedit

This guide explains how system administrators can disable modern lock screen image slideshows in Windows using the Registry Editor (Regedit). By configuring a dedicated policy in the Windows Registry, administrators can prevent users from enabling slideshows on the lock screen, thereby enforcing a static background, saving system resources, and maintaining a uniform appearance across managed endpoints.

Step-by-Step Registry Configuration

To disable the lock screen slideshow across the system, follow these steps:

  1. Open the Registry Editor
    Press Windows Key + R to open the Run dialog box, type regedit, and press Enter. If prompted by User Account Control (UAC), click Yes to grant administrative privileges.

  2. Navigate to the Personalization Policy Key
    In the Registry Editor, use the left-hand navigation pane to browse to the following path:
    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization

    Note: If the Personalization key does not exist under Windows, right-click on the Windows folder, select New > Key, and name the new key Personalization.

  3. Create the Policy Value
    Right-click in the empty space within the right-hand pane of the Personalization key, select New, and click DWORD (32-bit) Value.

  4. Name the Value
    Name the newly created value:
    NoLockScreenSlideshow

  5. Set the Value Data
    Double-click the NoLockScreenSlideshow value to open its properties. Set the Value data field to 1 and ensure the Base is set to Hexadecimal. Click OK to save the changes.

  6. Apply the Changes
    Close the Registry Editor. The changes take effect immediately, but a system restart or signing out and back in is recommended to verify that the lock screen slideshow functionality has been completely disabled in Windows Settings.

To revert this configuration and allow lock screen slideshows in the future, navigate back to the same registry path and either change the value data of NoLockScreenSlideshow to 0 or delete the NoLockScreenSlideshow entry entirely.
