How to set Custom backgrounds for Desktop and Lockscreen in Windows 10 Creators Update v1703 and later with PowerShell

Hi Friends, this is a quick blog to show how one can set Custom backgrounds for Desktop and Lock Screen in Windows 10 Creators Update v1703 and later with PowerShell.

I am sure people have been reading about the new features that were recently introduced with the release of Windows 10 build v1703 also known as The Creators Update. The Script here uses one of those new feature additions called PersonalizationCSP that empowers IT Administrators to set custom backgrounds for the Desktop and the Lock Screen as part of their Build and Capture sequence.

# The Script sets custom background Images for the Desktop and the Lock Screen by leveraging the new feature of PersonalizationCSP that is only available in the Windows 10 v1703 aka Creators Update and later build versions #

# Note: The Image File names can be anything you wish, however the Image resolution that I have been using for my environment was 3840X2160 (not sure if that matters though) #

# Applicable only for Windows 10 v1703 and later build versions #

# Script also assumes that you have already copied over the Desktop and LockScreen Images to the C:\OEMFiles\ folder and are named as Desktop.jpg and LockScreen.jpg respectively (could vary for your environment) #
$RegKeyPath = “HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\PersonalizationCSP”

$DesktopPath = “DesktopImagePath”
$DesktopStatus = “DesktopImageStatus”
$DesktopUrl = “DesktopImageUrl”
$LockScreenPath = “LockScreenImagePath”
$LockScreenStatus = “LockScreenImageStatus”
$LockScreenUrl = “LockScreenImageUrl”

$StatusValue = “1”
$DesktopImageValue = “C:\OEMFiles\Desktop.jpg”  #Change as per your needs
$LockScreenImageValue = “C:\OEMFiles\LockScreen.jpg”  #Change as per your needs

IF(!(Test-Path $RegKeyPath))

{

New-Item -Path $RegKeyPath -Force | Out-Null

New-ItemProperty -Path $RegKeyPath -Name $DesktopStatus -Value $StatusValue -PropertyType DWORD -Force | Out-Null
New-ItemProperty -Path $RegKeyPath -Name $LockScreenStatus -Value $StatusValue -PropertyType DWORD -Force | Out-Null
New-ItemProperty -Path $RegKeyPath -Name $DesktopPath -Value $DesktopImageValue -PropertyType STRING -Force | Out-Null
New-ItemProperty -Path $RegKeyPath -Name $DesktopUrl -Value $DesktopImageValue -PropertyType STRING -Force | Out-Null
New-ItemProperty -Path $RegKeyPath -Name $LockScreenPath -Value $LockScreenImageValue -PropertyType STRING -Force | Out-Null
New-ItemProperty -Path $RegKeyPath -Name $LockScreenUrl -Value $LockScreenImageValue -PropertyType STRING -Force | Out-Null

}

ELSE {

New-ItemProperty -Path $RegKeyPath -Name $DesktopStatus -Value $Statusvalue -PropertyType DWORD -Force | Out-Null
New-ItemProperty -Path $RegKeyPath -Name $LockScreenStatus -Value $value -PropertyType DWORD -Force | Out-Null
New-ItemProperty -Path $RegKeyPath -Name $DesktopPath -Value $DesktopImageValue -PropertyType STRING -Force | Out-Null
New-ItemProperty -Path $RegKeyPath -Name $DesktopUrl -Value $DesktopImageValue -PropertyType STRING -Force | Out-Null
New-ItemProperty -Path $RegKeyPath -Name $LockScreenPath -Value $LockScreenImageValue -PropertyType STRING -Force | Out-Null
New-ItemProperty -Path $RegKeyPath -Name $LockScreenUrl -Value $LockScreenImageValue -PropertyType STRING -Force | Out-Null
}
