Windows sign in screen background

Hello Abdul_Asath 

Welcome to the Microsoft community, my name is Recep I'll be happy to help you today.

Here are two potential approaches:

1. Custom Configuration Profile:

• You can try creating a custom configuration profile in Intune to deploy registry settings that control this behavior. This involves creating a custom OMA-URI setting.
• Navigate to "Devices" > "Configuration profiles" > "+ Create profile."

Choose the appropriate platform (Windows 10 or later).

Configure settings based on OMA-URI.

• Use the following settings for the OMA-URI:

OMA-URI: ./Device/Vendor/MSFT/Policy/Config/Personalization!LockScreenImageStatus

Data type: Integer

Value: 0 (to disable)

This setting might control the lock screen behavior. However, it's essential to test it in a controlled environment.

1. PowerShell Script:

Create a PowerShell script that modifies the necessary registry settings and deploy it through Intune as a PowerShell script.

# Disable lock screen background on sign-in screen

$registryPath = "HKLM:\SOFTWARE\Policies\Microsoft\Windows\Personalization"

$registryName = "NoLockScreen"

# Create registry key and set value to 1 to disable

New-Item -Path $registryPath -Force

New-ItemProperty -Path $registryPath -Name $registryName -Value 1 -PropertyType DWORD –Force

Deploy this script using Intune through a PowerShell script deployment.
