Yes. Verified that this works on Win 10 Pro 1709 OS Build 16299.19 across the enterprise.
Requires a ps script and regedit
I deployed via logon script (bat file)
Here is the ps script - this makes all the settings for the logged in user and changes the Lock Screen:
-----
# Change this to the path where you keep the desired background image
$imagePath = '(Path to Image, include single quotes)'
$newImagePath = [System.IO.Path]::GetDirectoryName($imagePath) + '\' + (New-Guid).Guid + [System.IO.Path]::GetExtension($imagePath)
Copy-Item $imagePath $newImagePath
[Windows.System.UserProfile.LockScreen,Windows.System.UserProfile,ContentType=WindowsRuntime] | Out-Null
Add-Type -AssemblyName System.Runtime.WindowsRuntime
$asTaskGeneric = ([System.WindowsRuntimeSystemExtensions].GetMethods() | ? { $_.Name -eq 'AsTask' -and $_.GetParameters().Count -eq 1 -and $_.GetParameters()[0].ParameterType.Name -eq 'IAsyncOperation`1' })[0]
Function Await($WinRtTask, $ResultType) {
$asTask = $asTaskGeneric.MakeGenericMethod($ResultType)
$netTask = $asTask.Invoke($null, @($WinRtTask))
$netTask.Wait(-1) | Out-Null
$netTask.Result
}
Function AwaitAction($WinRtAction) {
$asTask = ([System.WindowsRuntimeSystemExtensions].GetMethods() | ? { $_.Name -eq 'AsTask' -and $_.GetParameters().Count -eq 1 -and !$_.IsGenericMethod })[0]
$netTask = $asTask.Invoke($null, @($WinRtAction))
$netTask.Wait(-1) | Out-Null
}
[Windows.Storage.StorageFile,Windows.Storage,ContentType=WindowsRuntime] | Out-Null
$image = Await ([Windows.Storage.StorageFile]::GetFileFromPathAsync($newImagePath)) ([Windows.Storage.StorageFile])
AwaitAction ([Windows.System.UserProfile.LockScreen]::SetImageFileAsync($image))
Remove-Item $newImagePath
----------------
Here is the Regedit to Change Login Screen
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Creative\S-1-0-0]
"RotatingLockScreenEnabled"=dword:00000000
"LockImageFlags"=dword:00000000
"LockScreenOptions"=dword:00000000
"CreativeId"=""
"PortraitAssetPath"="(Path to Image, include double quotes, remember to use \\ in between folders)"
"LandscapeAssetPath"="(Path to Image, include double quotes, remember to use \\ in between folders)"
---------------
Here is the logon bat file
CLS
@echo off
regedit /S (insert path to .reg file here)
IF NOT EXIST (Local Path storing image) (
mkdir (Local Path storing image)
xcopy (From path) (Local Path storing image) /R /Y /I
) ELSE ECHO Applying Lock Screen
Powershell.exe -executionpolicy remotesigned -File (Path to ps1 file)
Exit
EXIT
Cheers!
