Windows Server 2025 must prevent the display of slide shows on the lock screen.

Slide shows displayed on the lock screen could display sensitive information to unauthorized personnel. Turning off this feature will limit access to the information to a logged-on user.

Verify the registry value below:

Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Policies\Microsoft\Windows\Personalization\

Value Name: NoLockScreenSlideshow

Value Type: REG_DWORD Value: 0x00000001 (1)

If the registry value does not exist or is not configured as specified, this is a finding.

Configure the policy value for Computer Configuration >> Administrative Templates >> Control Panel >> Personalization >> Prevent enabling lock screen slide show to "Enabled".
